AB  - Biocatalytic oxidations mediated by laccases are gaining importance due to their versatility and beneficial environmental effects. In this study, the oxidation of 1,4-dihydropyridines has been performed using three different types of bacterial laccase-based catalysts: purified laccase from Bacillus licheniformis ATCC 9945a (BliLacc), Escherichia coli whole cells expressing this laccase, and bacterial nanocellulose (BNC) supported BliLacc catalysts. The catalysts based on bacterial laccase were compared to the commercially available Trametes versicolor laccase (TvLacc). The oxidation product of 2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate was obtained within 7–24 h with good yields (70–99%) with all three biocatalysts. The substrate scope was examined with five additional 1,4-dihydropyridines, one of which was oxidized in high yield. Whole-cell biocatalyst was stable when stored for up to 1-month at 4 °C. In addition, evidence has been provided that multicopper oxidase CueO from the E. coli expression host contributed to the oxidation efficiency of the whole-cell biocatalyst. The immobilized whole-cell biocatalyst showed satisfactory activity and retained 37% of its original activity after three biotransformation cycles.

AB  - The consumption of dyes is increasing worldwide in line with the increase of population and demand for clothes and other colored products. However, the efficiency of dyeing processes is still poor and results in large amounts of colored effluents. It is desired to develop a portfolio of enzymes which can be used for the treatment of colored wastewaters. Herein, we used genome sequence information to discover a dye-decolorizing peroxidase (DyP) from Pseudomonas fluorescens Pf-01. Two genes putatively encoding for DyPs were identified in the respective genome and cloned for expression in Escherichia coli, of which one (Pf DyP B2) could be overexpressed as a soluble protein. Pf DyP B2 shows some typical features known for DyPs which includes the ability to convert dyes at the expense of hydrogen peroxide. Interestingly, t-butyl hydroperoxide could be used as an alternative substrate to hydrogen peroxide. Immobilization of Pf DyP B2 in calcium-alginate beads resulted in a significant increase in stability: Pf DyP B2 retains 80% of its initial activity after 2 h incubation at 50◦ C, while the soluble enzyme is inactivated within minutes. Pf DyP B2 was also tested with aniline and ethyl diazoacetate as substrates. Based on GC-MS analyses, 30% conversion of the starting material was achieved after 65 h at 30◦ C. Importantly, this is the first report of a DyP-catalyzed insertion of a carbene into an N-H bond.

AB  - Lignocellulosic plant biomass is the world’s most abundant carbon source and has consequently attracted attention as a renewable resource for production of biofuels and commodity chemicals that could replace fossil resources. Due to its recalcitrant nature, it must be pretreated by chemical, physical or biological means prior to hydrolysis, introducing additional costs. In this paper, we tested the hypothesis that fungi which thrive on lignocellulosic material (straw, bark or soil) would be efficient in degrading untreated lignocellulose. Wheat straw was used as a model. We developed a fast and simple screening method for cellulase producers and tested one hundred Trichoderma strains isolated from wheat straw. The most potent strain—UB483FTG2/ TUCIM 4455, was isolated from substrate used for mushroom cultivation and was identified as T. guizhouense. After optimization of growth medium, high cellulase activity was already achieved after 72 h of fermentation on raw wheat straw, while the model cellulase overproducing strain T. reesei QM 9414 took 170 h and reached only 45% of the cellulase activity secreted by T. guizhouense. Maximum production levels were 1.1 U/mL (measured with CMC as cellulase substrate) and 0.7 U/mL (β-glucosidase assay). The T. guizhouense cellulase cocktail hydrolyzed raw wheat straw within 35 h. Our study shows that screening for fungi that successfully compete for special substrates in nature will lead to the isolation of strains with qualitatively and quantitatively superior enzymes needed for their digestion which could be used for industrial purposes.

AB  - In this study we investigated physiological parameters of stress (enzymatic and non-enzymatic) in lettuce (Lactuca sativa L.) and its hairy roots induced by water solution of phenol. Two varieties of lettuce were examined, Ljubljanska ledenka and Nansen. Plants were grown in water with phenol concentration of 200 mgL(-1), during 10 days. We monitored activity of peroxidases, catalases, polyphenol oxidase and superoxide dismutase, as well as proline and chlorophyll content. We observed a decrease in peroxidases, and increase in activity of catalase, polyphenol oxidase and superoxide dismutase compared to control plants. The concentration of praline was constantly increasing in both lettuce varieties over the course of the experiment. We detected an increase in activity of all monitored enzymes, except polyphenol oxidases, in hairy roots. The hydroponic system provides a useful framework for studying the effect of different harmful substances and its elimination. In such a system, as used in this work for the study of physiological processes in antioxidant protection activated when plant was exposed to phenol, lettuce and its hairy roots can be viewed as tools for water remediation.

abstract = "In this study we investigated physiological parameters of stress (enzymatic and non-enzymatic) in lettuce (Lactuca sativa L.) and its hairy roots induced by water solution of phenol. Two varieties of lettuce were examined, Ljubljanska ledenka and Nansen. Plants were grown in water with phenol concentration of 200 mgL(-1), during 10 days. We monitored activity of peroxidases, catalases, polyphenol oxidase and superoxide dismutase, as well as proline and chlorophyll content. We observed a decrease in peroxidases, and increase in activity of catalase, polyphenol oxidase and superoxide dismutase compared to control plants. The concentration of praline was constantly increasing in both lettuce varieties over the course of the experiment. We detected an increase in activity of all monitored enzymes, except polyphenol oxidases, in hairy roots. The hydroponic system provides a useful framework for studying the effect of different harmful substances and its elimination. In such a system, as used in this work for the study of physiological processes in antioxidant protection activated when plant was exposed to phenol, lettuce and its hairy roots can be viewed as tools for water remediation.",

AB  - BACKGROUND: The need to increase the daily intake of dietary fibres opens a new chapter in the research of functional foods enriched with fibres. The potential application of an innovative product - insoluble dietary fibres from triticale in yoghurts - was deployed by characterising their food application and evaluating physico-chemical, rheological and sensory properties and was the aim of this research. RESULTS: Detailed characterisations of these fibres are presented for the first time and showed very good hydration properties, optimal pH ( slightly acidic), optimal chemical composition, high antioxidant capacity which was proven by phenolics contents. Besides, these fibres showed negligible calorific value, with no phytates and high antioxidant capacity, mainly from ferulic acid. Therefore they could be successfully added to yoghurt. Enrichment of yoghurt having different milk fat content (1.5 and 2.8% w/w) with triticale insoluble fibre (1.5% and 3.0% w/w) significantly influenced the syneresis level, its apparent viscosity, yield stress and thixotropic behaviour. The overall sensory quality scores indicated that yoghurt enriched with 1.5% triticale insoluble fibres was recognised as 'excellent' and had enhanced antioxidant activity. CONCLUSIONS: Insoluble triticale fibre could therefore be used as a supplement to produce functional yoghurt. (c) 2017 Society of Chemical Industry

AB  - We investigated the removal of phenol from water solutions (200 mg L-1) using two varieties of lettuce (Lactuca sativa L) and their hairy roots. Experiments were done in a hydroponic system where adult plants were grown in phenol solutions for 10 days. The solution was refreshed every two days in order to maintain the constant concentration of phenol. Hairy roots were also cultivated in a solution containing phenol at concentrations varying from 25 to 125 mg L-1 in order to determine the maximum concentration of phenol that can be removed by hairy roots. Both varieties of lettuce reduced the concentration of phenol below the detection limit after six days at the initial phenol concentration of 200 mg L-1. Transformed roots completely removed phenol at the initial concentrations of 100 mg L-1, but were not able to remove phenol at constant concentration above 25 mg L-1. Lettuce plants and hairy roots are excellent candidates for the process of phenol removal from wastewaters. This plant is good choice for bioremediation of water and represents a potentially efficient and inexpensive system for water purification. The performance of lettuce plants and hairy roots to remove phenol from water solutions under real conditions, depleted nutrients or presence of other compounds should be examined further.

AB  - Use of foodomics, mostly proteomic and genomic based methods, for study of allergens in food is presented. Immunological methods and nucleic acid-based methods are still most frequently used for diagnosis of allergies and for qualitative and quantitative determination of food allergens. They are sensitive, and can be used for the determination of allergens in trace concentrations. However, lack of specificity and cross-reaction of some antibodies can still be a relevant source of bias. The epitopes of protein allergens with posttranslational modifications and their changes originated during food processing cannot be traced by use of nucleic acid-based strategies. Recent developments of both antibody and nucleic acid-based biosensors, their miniaturization and increasing application of nanotechnology, significantly supported further use of both strategies. Regarding accuracy, reliability and sensitivity, mass spectrometry-based methods bring important advantage over both above presented strategies. Furthermore, the increasing use of mass spectrometry (MS) is discussed. Combined with proper sample preparation, liquid chromatography (LC) and/or different electrophoretic methods, targeted approach in mass spectrometry-based allergen analysis brings an additional strategic advance. However, MS is still rarely used for high-throughput analyses and detection and quantification of allergens for the reasons of price and relatively long time necessary for analysis. Recent developments of new high-resolution instruments are encouraging and enable development in the direction of a high-throughput strategy. Consequently, fast, very sensitive, reliable and accurate detection and quantification of allergens in highly complex samples such as food matrices, and the use of MS in routine determination of allergens can be reached in near future.

AB  - The exclusive properties of monolithic supports enable fast mass transfer, high porosity, low back pressure, easy preparation process and miniaturisation, and the availability of different chemistries make them particularly suitable materials for high-throughput (HTP) protein and peptide separation. In this review recent advances in monolith-based chromatographic supports for HTP screening of protein and peptide samples are presented and their application in HTP sample preparation (separation, enrichment, depletion, proteolytic digestion) for HTP proteomics is discussed. Development and applications of different monolithic capillary columns in HTP MS-based bottom-up and top-down proteomics are overviewed. By discussing the chromatographic conditions and the mass spectrometric data acquisition conditions an attempt is made to present currently demonstrated capacities of monolithic capillary columns for HTP identification and quantification of proteins and peptides from complex biological samples by MS-based proteomics. Some recent advances in basic monolith technology of importance for proteomics are also discussed.

AB  - The exclusive properties of monolithic supports enable fast mass transfer, high porosity, low back pressure, easy preparation process and miniaturisation, and the availability of different chemistries make them particularly suitable materials for high-throughput (HTP) protein and peptide separation. In this review recent advances in monolith-based chromatographic supports for HTP screening of protein and peptide samples are presented and their application in HTP sample preparation (separation, enrichment, depletion, proteolytic digestion) for HTP proteomics is discussed. Development and applications of different monolithic capillary columns in HTP MS-based bottom-up and top-down proteomics are overviewed. By discussing the chromatographic conditions and the mass spectrometric data acquisition conditions an attempt is made to present currently demonstrated capacities of monolithic capillary columns for HTP identification and quantification of proteins and peptides from complex biological samples by MS-based proteomics. Some recent advances in basic monolith technology of importance for proteomics are also discussed.

AB  - Fortification of fermented dairy products with insoluble dietary fiber is an interesting way to increase consumers' fiber intake. The objective of this study was to evaluate the sensory characteristics and consumer acceptance of low-fat unsweetened yoghurt, fortified at levels of 15 and 30 g/kg, with insoluble triticale, wheat or oat fibers. The addition of insoluble triticale fiber resulted in yellowish-brown color, grainy flavor, and pronounced sandiness/grittiness of the fortified yoghurts. The products were classified into the 'very good' quality category, despite the lower quality scores given to the 30 g/kg fiber fortified yoghurts, caused primarily by a gritty/sandy texture and some bitterness. Three distinct consumer subgroups were revealed by the clustering analysis, one of which showed a preference for the triticale-yoghurts. Insoluble dietary fiber from triticale showed promising potential to be used as a fortifying ingredient in the production of fiber-enriched fermented dairy products such as yoghurt.

AB  - The aim of this study was to investigate the impact of dyes on DNA before and after enzymatic decolorization by acidic horseradish peroxidase (HRP-A). The comet assay is easy and feasible method widely used to measure DNA damage and repair. The medium-throughput comet assay was employed for assessment of genotoxic effects of 8 dyes in BEAS-2B cells. We have incorporated a digestion with bacterial endonuclease (formamidopyrimidine DNA glycosylase, FPG) to detect oxidized bases in the case of single and double azo dyes, Orange II (OR2) and Amido Black 10B (AB), respectively. This allowed detection 8-oxo7,8-dihydroguanine, one of most abundant oxidized bases in nuclear DNA. In the case of AB there was no indication of DNA damage, either strand brakes or FPG-sensitive sites before and after decolorization. The OR2 induced DNA damage (in terms of percentage of DNA in comet tails). Also, the frequency of FPG-sensitive sites increased with OR2 concentration. After decolorization no DNA damaging effects was seen at all. The interaction studies of OR2 and AB, before and after decolorization, with calf thymus DNA has been investigated by absorption and fluorescence spectroscopy. The results provide support for the idea that in some cases enzymatic decolorization contributes to lower genotoxicity potential. (C) 2016 Elsevier B.V. All rights reserved.

AB  - Peroxidases (EC 1.11.1.7) have enormous biotechnological applications. Usage of more abundant, basic isoforms of peroxidases in diagnostic kits and/or in immunochemistry has led to under exploitation and disregard of horseradish peroxidase (HRP) acidic isoforms. Therefore, acidic horseradish peroxidase (HRP-A) isoenzymewas used for the preparation of a biocatalyst with improved ability in dye decolorization. Ten biocatalysts were prepared by covalent binding of enzyme to chitosan and alginate, adsorption followed by cross-linking on inorganic support (aluminum oxide), and encapsulation in spherical calcium alginate beads via polyethylene glycol. Model dyes of 50 to 175 mg l(-1) were removed by the biocatalysts. Among the tested biocatalysts, the three with the highest specific activity and biodegradation rate were further studied (Chitosan-HRP, Al-GelHRP and Al-HRP-Gel). The impact of hydrogen peroxide concentration on dye decolorization was examined on the Chitosan-HRP biocatalyst, since the HRP is susceptible to inhibition/inactivation by high H2O2. On the other hand, H2O2 is needed as a co-substrate for the HRP, and the H2O2/dye ratio can greatly influence decolorization efficiency. Concentrations of H2O2 ranging from 0.22 to 4.4 mM showed no difference in terms of impact on the biocatalyst decolorization efficiency. The high decolorization efficiency of the biocatalysts was validated by the removal of 25 and 100 mg l(-1) anthraquinone (Remazol Brilliant Blue R (RBBR)), triphenylmethane (Coomassie Brilliant Blue CBB)), acridine (Acridine Orange (AO)), and formazan metal complex dye (Reactive Blue 52 (RB52)). After the seven consecutive decolorization cycles, the decolorization was still 53, 78, and 67% of the initial dye for the Al-HRP-Gel, Al-Gel-HRP, and Chitosan-HRP immobilizate, respectively.

abstract = "Peroxidases (EC 1.11.1.7) have enormous biotechnological applications. Usage of more abundant, basic isoforms of peroxidases in diagnostic kits and/or in immunochemistry has led to under exploitation and disregard of horseradish peroxidase (HRP) acidic isoforms. Therefore, acidic horseradish peroxidase (HRP-A) isoenzymewas used for the preparation of a biocatalyst with improved ability in dye decolorization. Ten biocatalysts were prepared by covalent binding of enzyme to chitosan and alginate, adsorption followed by cross-linking on inorganic support (aluminum oxide), and encapsulation in spherical calcium alginate beads via polyethylene glycol. Model dyes of 50 to 175 mg l(-1) were removed by the biocatalysts. Among the tested biocatalysts, the three with the highest specific activity and biodegradation rate were further studied (Chitosan-HRP, Al-GelHRP and Al-HRP-Gel). The impact of hydrogen peroxide concentration on dye decolorization was examined on the Chitosan-HRP biocatalyst, since the HRP is susceptible to inhibition/inactivation by high H2O2. On the other hand, H2O2 is needed as a co-substrate for the HRP, and the H2O2/dye ratio can greatly influence decolorization efficiency. Concentrations of H2O2 ranging from 0.22 to 4.4 mM showed no difference in terms of impact on the biocatalyst decolorization efficiency. The high decolorization efficiency of the biocatalysts was validated by the removal of 25 and 100 mg l(-1) anthraquinone (Remazol Brilliant Blue R (RBBR)), triphenylmethane (Coomassie Brilliant Blue CBB)), acridine (Acridine Orange (AO)), and formazan metal complex dye (Reactive Blue 52 (RB52)). After the seven consecutive decolorization cycles, the decolorization was still 53, 78, and 67% of the initial dye for the Al-HRP-Gel, Al-Gel-HRP, and Chitosan-HRP immobilizate, respectively. The results obtained showed potential of otherwise neglected acidic HRP isoforms as a cost-effective biocatalyst with significant potential in wastewater dyestuff treatment.",

AB  - Yeast Saccharomyces cerevisiae is the most significant source of enzyme invertase. It is mainly used in the food industry as a soluble or immobilized enzyme. The greatest amount of invertase is located in the periplasmic space in yeast. In this work, it was isolated into two forms of enzyme from yeast S. cerevisiae cell, soluble and cell wall invertase (CWI). Both forms of enzyme showed same temperature optimum (60 degrees C), similar pH optimum, and kinetic parameters. The significant difference between these biocatalysts was observed in their thermal stability, stability in urea and methanol solution. At 60 degrees C, CWI had 1.7 times longer half-life than soluble enzyme, while at 70 degrees C CWI showed 8.7 times longer half-life than soluble enzyme. After 2-hr of incubation in 8M urea solution, soluble invertase and CWI retained 10 and 60% of its initial activity, respectively. During 22hr of incubation of both enzymes in 30 and 40% methanol, soluble invertase was completely inactivated, while CWI changed its activity within the experimental error. Therefore, soluble invertase and CWI have not shown any substantial difference, but CWI showed better thermal stability and stability in some of the typical protein-denaturing agents.

AB  - The aim of this study was to determine the enzymatic profile of esterases and peroxidases during early stages of somatic embryogenesis of Fritillaria meleagris L. Somatic embryogenesis was induced using the leaf base as explant on a medium supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D). Zymography showed the presence of different moieties, six isoforms of esterases and peroxidases, during morphogenesis as compared to control explants. One isoform of esterases was detected only during the process of somatic embryogenesis, and one isoform was detected in control explants. Analysis of esterases with 1-naphthyl butyrate proved that esterases, which participate in somatic embryogenesis of F. meleagris, belong to the family of aryl esterases. For the first time it was proved that five isoforms of esterases, which are involved in morphogenesis of F. meleagris, belong to the family of aryl esterases, while two isoforms are carboxyl esterases. One isoform of carboxyl esterases was visible in control explants. This is also the first description of peroxidases during the morphogenetic process, and of the difference between aryl and carboxyl esterases. More isoforms of esterases during morphogenesis as compared to control explants are probably responsible for some early physiological process during somatic embryogenesis of F. meleagris.

AB  - Use of foodomics, mostly proteomic and genomic based methods, for study of allergens in food is presented. Immunological methods and nucleic acid-based methods are still most frequently used for diagnosis of allergies and for qualitative and quantitative determination of food allergens. They are sensitive, and can be used for the determination of allergens in trace concentrations. However, lack of specificity and cross-reaction of some antibodies can still be a relevant source of bias. The epitopes of protein allergens with posttranslational modifications and their changes originated during food processing cannot be traced by use of nucleic acid-based strategies. Recent developments of both antibody and nucleic acid-based biosensors, their miniaturization and increasing application of nanotechnology, significantly supported further use of both strategies. Regarding accuracy, reliability and sensitivity, mass spectrometry-based methods bring important advantage over both above presented strategies. Furthermore, the increasing use of mass spectrometry (MS) is discussed. Combined with proper sample preparation, liquid chromatography (LC) and/or different electrophoretic methods, targeted approach in mass spectrometry-based allergen analysis brings an additional strategic advance. However, MS is still rarely used for high-throughput analyses and detection and quantification of allergens for the reasons of price and relatively long time necessary for analysis. Recent developments of new high-resolution instruments are encouraging and enable development in the direction of a high-throughput strategy. Consequently, fast, very sensitive, reliable and accurate detection and quantification of allergens in highly complex samples such as food matrices, and the use of MS in routine determination of allergens can be reached in near future.

Endocellulase wasdetected on polyacrilamide gel with copolymerized carboxymethyl-cellulose andexocellulase were detected using 4-metillumberiferil-β-D-celobioside as a substrate.Reuse of spent mushroom compost as a new substrate for the production ofcellulase enzymes by 6 isolates Trichoderma spp. was examined here too. Significantamount of endocellulase and β-glucosidase were produced, while the amount of initialsubstrate decreased by 30%.The regulation mechanism of protein production of isolate UB483FTH2 analysedas a correlation of transcribed level of mRNA for genes xyr1 and lae1 as a regulators ofproduction of cellulase enzymes. It was found that expressed genes xyr1 and lae1 have apositive effect on the production of cellulases proteins and total proteins.",

AB  - Bacterial laccases have proven advantages over fungal and plant counterparts in terms of wider pH optimum, higher stability and broader biocatalytic scope. In this work, Bacillus licheniformis ATCC 9945a laccase is produced heterologously in Escherichia coli. Produced laccase exhibits remarkably high temperature optimum at 90 degrees C and possess significant thermostability and resistance to inactivation by organic solvents. Laccase has an apparent melting temperature of 79 degrees C at pH 7.0 and above 70 degrees C in range of pH 5.0-8.0, while having half-life of 50 min at 70 degrees C. Presence of 10% organic solvents such as acetonitrile, dimethylformamide, dimethylsulfoxide or methanol reduces melting temperature to 45-52 degrees C but activity remains practically unimpaired. With 50% of acetonitrile and methanol laccase retained similar to 40% of initial activity. EDTA and 300 mM sodium -chloride have positive effect on activity. Enzyme is active on syringaldazine, ABTS, phenols, amines, naphthol, lignin and lignin model compounds and mediates C-C bond formation via oxidative coupling after one electron oxidation of phenolic group. Successful polymerization of 2 -naphthol was achieved with 77% conversion of 250 mg/L 2-naphtol in only 15 min which may further expand substrate scope of this enzyme towards polymer production and/or xenobiotics removal for environmental applications.

AB  - Dye-decolorizing peroxidases (DyPs) represent a new class of oxidative enzymes for which the natural substrates are largely unknown. To explore the biocatalytic potential of a DyP, we have studied the substrate acceptance profile of a robust DyP peroxidase, a DyP from Thermobifida fusca (TfuDyP). While previous work established that this bacterial peroxidase is able to act on a few reactive dyes and aromatic sulfides, this work significantly expands its substrate scope towards lignin related compounds, flavors, and various dyes.
