AB  - The combination ofb-oligosaccharides from enzymatically hydrolysed barleyb-glucan has attracted inter-est recently due to its positive effects on human health. This study aimed to assess the impact of theendo-b-1,3-1,4-glucanase enzyme fromBacillus  subtilis168 on improving the nutritional and bioactiveproperties of barleyb-glucan. A new procedure for the isolation ofb-glucan was developed, at a lowertemperature (45°C), enabling purity from starch contamination, without affecting the yield (6 gb-glucanfrom 100 g of barley flour). The endo-b-1,3-1,4-glucanase is cloned intoE. colipQE_Ek enables the highproduction and purification (82% yield, 1.8 mg mL 1and 440 U mg 1) of an enzyme identical to thenatural one (25.5 kDa). The enzymatic reaction showed high efficiency ofb-glucan degradation by recom-binant enzyme, giving a mixture of products (of which 3-O-b-cellobiosyl-D-glucose and 3-O-b-cellotriosyl-D-glucose are the most abundant), the reduction of viscosity (17%) and increase in antioxidant capacitiesby 15.2%, 30.9% and 44.0% assessed by ABTS, DPPH and ORAC, respectively. These results indicatethe possible application of endo-b-1,3-1,4-glucanase enzyme in improving the properties of barleyb-glucan used as functional foods.

AB  - Bioethanol is one of the main bio-based molecules produced mainly from sugar cane, molasses and corn. Its environmental advantages allow it to be considered as safe and the cleanest fuel alternative. Starch is a widespread renewable carbohydrate conventionally used for bioethanol production via energy demanding liquefaction and saccharification processes. Raw starch hydrolysis using enzymes capable of degrading it below the gelatinization temperature significantly simplifies the process and reduces the cost of starch processing. In this study, an innovative modified simultaneous saccharification and fermentation process is proposed for the production of bioethanol from highly concentrated raw corn starch (30 % w/v). A two-step synergistic hydrolysis and fermentation was carried out in a single bioreactor vessel. To ensure high process efficiency, factors influencing the hydrolysis of concentrated raw corn starch by raw starch degrading α-amylase from Bacillus paralicheniformis ATCC 9945a (BliAmy) and commercial glucoamylase were investigated. Box–Behnken experimental design was used to predict the effects of different ratios of added enzymes, glucoamylase addition time, incubation time, and pH on hydrolysis yield. Optimal conditions for the highest yield of hydrolysis of raw corn starch (90 %) were obtained after 8 h using 5.0 IU BliAmy per mg of starch and 0.5 % (v/v) glucoamylase at pH 4.5 and 60 °C. Obtained glucose was further fermented with Saccharomyces cerevisiae at 30 °C in the same vessel for bioethanol production. Bioethanol concentration at 129.2 g/L, with productivity of 2.94 g/L/h and ethanol yield (YP/S) at 0.50 g EtOH/g total sugar, equivalent to 87.8 % theoretical yield, was obtained by modified simultaneous saccharification and fermentation. This work enriches the information of bioethanol production and offers a novel strategy for raw starch hydrolysis under industrial conditions.

AB  - Finding a pollen substitute for honey bees that is nutritionally adequate and affordable is a scientific and practical challenge. We attempted a new rational approach and tried to exploit honey bees’ natural cannibalistic behavior. We tested processed insect larvae as a food source that is nutritionally similar to bee brood, and which can easily be produced on a large scale. In cage experiments, monitoring bee mortality, food consumption and changes in bee body parts’ weights showed that flour obtained by grinding dried yellow mealworm larvae has the potential to become an excellent component for pollen substitution. Bees from the cage group fed Tenebrio molitor patties (TG) demonstrated overall best results in comparison to sugar patties fed bee group (CG), yeast patties fed bee group (YG) and pollen patties fed bee group (PG). They did not lose weight as rapidly as the CG, did not defecate inside cages as the YG, nor show increased mortality as the PG. At the same time, TG consumed less food (mean 13.7 g/cage) than CG (16.8 g/cage), YG (20.4 g/cage) and PG (23.9 g/cage) within the period of 28 days. Bees’ gut increase in weight was lowest in the CG, followed by TG and PG and was the highest in the YG which resulted in diarrhea after 14 days. Bees from TG did not lag behind other bees in head, thorax and abdomen weight after 28 days. We demonstrated that processed yellow mealworm larvae (T. molitor) can be used as an ingredient for honey bee feed.

AB  - Production of fructooligosaccharides (FOS) is a trending topic due to their prebiotic effect becoming increasingly important for the modern human diet. The most suitable process for FOS production is the one using fungal inulinases. Introduction of new fungal inulinase producers and their implementation in production of inulinase enzymes is therefore gaining interest. This study provides a new approach to FOS synthesis by fungal enzyme complex without prior separation of any specific enzyme. Inulinase enzyme complexes could be used for the synthesis of FOS in two possible ways – hydrolysis of inulin (FOSh) and transfructosylation process of sucrose (FOSs), as demonstrated here. Depending on the fungal growth inducing substrate, a variety of inulinase enzyme complexes was obtained – one of which was most successful in production of FOSh and another one of FOSs. Substrates derived from crops: triticale, wheat bran, Jerusalem artichoke and Aspergillus welwitschiae isolate, previously proven as safe for use in food, were utilized for production of inulinase enzyme cocktails. The highest FOSs production was obtained by enzyme complex rich in β-fructofuranosidase, while the highest FOSh production was obtained by enzyme complex rich in endoinulinase. Both FOSh and FOSs showed antioxidant potential according to ABTS and ORAC, which classifies them as a suitable additive in functional food. Simultaneous zymographic detection of inulinase enzymes, which could contribute to expansion of the knowledge on fungal enzymes, was developed and applied here. It demonstrated the presence of different inulinase isoforms depending on fungal growth substrate. These findings, which rely on the innate ability of fungi to co-produce all inulinases from a cocktail, could be useful as a new, easy approach to FOS production by fungal enzymes without their separation and purification, contributing to cheaper and faster production processes.

AB  - Pectinases are widely used in the fruit juice industry for clarification, liquefaction and stabilization of juices1. One of the biggest problems in the production of fruit juices is the turbidity of the juice, which is mainly caused by the presence of pectin polysaccharides. Therefore, pectinase is used in juice clarification, which breaks down the pectin structure and reduces unwanted cloudiness and sediment2. In this work, the production of pectinases was optimized by solid state fermentation using Aspergillus tubingensis strain, which proved to be an efficient producer of these enzymes. Statistical method Design of Experiment was used to optimize the medium and conditions for enzyme production. The total pectinase activity obtained was determined by the DNS method (47 U/mL). Endo-pectinases activity is determined by reduction of viscosity of pectin solutions. The resulting complex of pectinase enzymes was used for the liquefaction of apricot and blueberry pulp, with a juice yield of 72% and 81%, respectively. Also, apricot juice treated with enzymes was clarified by 77% compared to juice that was not treated with enzymes. Blueberry juice obtained after treatment with pectinase enzymes has a higher antioxidant activity than the untreated juice, as determined by the DPPH assay.

AB  - One of the most abundant natural polymers with multidimensional and multifaceted application is starch. Due to energy fuel sustainability concern, the world is focusing on renewable energy including energy from renewable biological materials like starch1. The importance of the enzymatic hydrolysis of granular starch below the temperature of gelatinization has been well recognized, mainly due to energy savings and the effective utilization of biomass, which reduces the overall cost of starch processing2. A new α-amylase gene (Amy35) was cloned from newly isolated thermophilic Anoxybacillus sp. ST4 and expressed in Escherichia coli. The purified recombinant α-amylase had an wide pH optimum range from 4.5 to 8.5 and optimum temperature of 75°C. The enzyme retained 95% of its activity after 3h of incubation at 50 and 60°C. Hydrolysis rates of potato, horseradish and corn starches, at 1% concentration were 20, 70 and 65%, respectively, in a period of 16 h. Analysis of the enzyme properties proved its high efficacy for the digestion of diverse raw starches below gelatinization temperature and, therefore, its potential commercial value for use as an industrial enzyme.

AB  - There is an urgent need to increase the daily intake of insoluble dietary fiber, and at the same time to find new sources and new production technologies. We hypothesized that fungal enzymes directly involved in lignocellulosic material hydrolysis (Aspergillus and Trichoderma enzyme cocktails) will change the fiber structure particularly efficiently after the action of laccase (Trametes versicolor enzyme cocktail). Enzymes production on an inducing substrate (same as starting material for obtainment of insoluble dietary fibers) and their usage resulted in obtainment of novel insoluble dietary fibers with better characteristics, 24% higher swelling, 43% higher WRC and 57% higher ORC compared to insoluble dietary fibers from triticale (already proven to be a good food additive). Changes in structure were analyzed by FTIR and microscopic analysis. Antioxidative performance of the obtained products, new insoluble and released soluble dietary fibers, was analyzed in detail. Newly obtained soluble dietary fibers demonstrated up to 20 times higher antioxidant activity compared to untreated fibers (ABTS and DPPH tests). These results suggest their good performance as a future food additive. At the same time, they prove the hypothesis that the use of enzyme cocktails rich in laccase is a good choice for biological pretreatment in this process.

AB  - Duckweed (L. minor) is a cosmopolitan aquatic plant of simplified morphology and rapid vegetative reproduction. In this study, an H. paralvei bacterial strain and its influence on the antioxidative response of the duckweeds to phenol, a recalcitrant environmental pollutant, were investigated. Sterile duckweed cultures were inoculated with H. paralvei in vitro and cultivated in the presence or absence of phenol (500 mg L−1), in order to investigate bacterial effects on plant oxidative stress during 5 days. Total soluble proteins, guaiacol peroxidase expression, concentration of hydrogen peroxide and malondialdehyde as well as the total ascorbic acid of the plants were monitored. Moreover, bacterial production of indole-3-acetic acid (IAA) was measured in order to investigate H. paralvei’s influence on plant growth. In general, the addition of phenol elevated all biochemical parameters in L. minor except AsA and total soluble proteins. Phenol as well as bacteria influenced the expression of guaiacol peroxidase. Different isoforms were associated with phenol compared to isoforms expressed in phenol-free medium. Considering that duckweeds showed increased antioxidative parameters in the presence of phenol, it can be assumed that the measured parameters might be involved in the plant’s defense system. H. paralvei is an IAA producer and its presence in the rhizosphere of duckweeds decreased the oxidative stress of the plants, which can be taken as evidence that this bacterial strain acts protectively on the plants during phenol exposure.

AB  - α-Amylase from Bacillus paralicheniformis (BliAmy), belonging to GH13_5 subfamily of glycoside hydrolases, was proven to be a highly efficient raw starch digesting enzyme. The ability of some α-amylases to hydrolyze raw starch is related to the existence of surface binding sites (SBSs) for polysaccharides that can be distant from the active site. Crystallographic studies performed on BliAmy in the apo form and of enzyme bound with different oligosaccharides and oligosaccharide precursors revealed binding of these ligands to one SBS with two amino acids F257 and Y358 mainly involved in complex formation. The role of this SBS in starch binding and degradation was probed by designing enzyme variants mutated in this region (F257A and Y358A). Kinetic studies with different substrates show that starch binding through the SBS is disrupted in the mutants and that F257 and Y358 contributed cumulatively to binding and hydrolysis. Mutation of both sites (F257A/Y358A) resulted in a 5-fold lower efficacy with raw starch as substrate and at least 5.5-fold weaker binding compared to the wild type BliAmy, suggesting that the ability of BliAmy to hydrolyze raw starch with high efficiency is related to the level of its adsorption onto starch granules.

The ability of some α-amylases to hydrolyze raw starch is related to the existence of surface binding sites (SBSs) for polysaccharides that can be distant from the active site. Crystallographic studies performed on BliAmy in the apo form and of enzyme bound with different oligosaccharides and oligosaccharide precursors revealed binding of these ligands to one SBS with two amino acids F257 and Y358 mainly involved in complex formation. The role of this SBS in starch binding and degradation was probed by designing enzyme variants mutated in this region (F257A and Y358A). Kinetic studies with different substrates show that starch binding through the SBS is disrupted in the mutants and that F257 and Y358 contributed cumulatively to binding and hydrolysis. Mutation of both sites (F257A/Y358A) resulted in a 5-fold lower efficacy with raw starch as substrate and at least 5.5-fold weaker binding compared to the wild type BliAmy, suggesting that the ability of BliAmy to hydrolyze raw starch with high efficiency is related to the level of its adsorption onto starch granules.

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  - Invertases are glycosidases applied for synthesis of alkyl glycosides that are important and effective surfactants. Stability of invertases in the environment with increased content of organic solvent is crucial for increase of productivity of glycosidases. Their stabilityis significantly influenced by N-glycosylation. However, yeast N-glycosylation pathways may synthesize plethora of N-glycan structures. A total natural crude mixture of invertase glycoforms (EINV) extracted from Saccharomyces cerevisiae was subfractionatedby anion-exchange chromatography on industrial monolithic supports to obtain different glycoforms (EINV1–EINV3). Separated glycoforms exhibited different stabilities in wateralcohol solutions that are in direct correlation with the amount of phosphate bound to N-glycans. Observed differences in stability of different invertase glycoforms were used to improve productivity of methyl β-d-fructofuranoside (MF) synthesis. The efficiency and yield of MF synthesis were improved more than 50% when the most stabile glycoform bearing the lowest amount of phosphorylated N-glycans is selected and utilized. These data underline the importance of analysis of glycan structures attached to glycoproteins, demonstrate different impact of N-glycans on the surface charge and enzyme stability inregard to particular reaction environment, and provide a platform for improvement of yield of industrial enzymatic synthesis by chromatographic selection of glycoforms on monolithic supports.

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  - 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  - Binding of three ruthenium(ii) compounds of general formula mer-[Ru(L3)(N-N)X][Y] (where L3 = 4-chloro-2,2:6,2-terpyridine (Cl-tpy); N-N = 1,2-diaminoethane (en), 1,2-diaminocyclohexane (dach) or 2,2-bipyridine (bipy); X = Cl; Y = Cl) to human serum albumin (HSA) has been investigated by nano-LC/nano-ESI MS and docking studies. A bottom-up proteomics approach has been applied for the structural characterization of metallated proteins and the data were analyzed in both the positive and negative ion mode. The negative ion mode was achieved after the post-column addition of an isopropanol solution of formaldehyde that enabled sample ionization at micro-flow rates. The negative ion mode MS has been proved to be beneficial for the analysis of binding sites on ruthenated protein in terms of ion charge reduction and consequent simplification of target sequence identification based on isotopic differences between ruthenated and non-ruthenated peptides. Moreover, the negative ion mode ESI MS shows the advantage of singly charged ion formation and, unlike MALDI MS, it does not cause complete ligand fragmentation, merging the benefits of each method into a single experiment. Six target sequences were identified for the binding of en and dach compounds, and four sequences for the binding of bipy. All compounds have been found to bind histidine and one aspartate residue. Docking studies showed that the identified sequences are the constituents of five distinct binding sites for en and dach, or two sites for the bipy complex. The selection of binding sites seems to be dependent on the chelate ligand and the form of the complex prior or after hydrolysis of the leaving chloride ligand.

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.

AB  - Binding of three ruthenium(ii) compounds of general formula mer-[Ru(L3)(N-N)X][Y] (where L3 = 4-chloro-2,2:6,2-terpyridine (Cl-tpy); N-N = 1,2-diaminoethane (en), 1,2-diaminocyclohexane (dach) or 2,2-bipyridine (bipy); X = Cl; Y = Cl) to human serum albumin (HSA) has been investigated by nano-LC/nano-ESI MS and docking studies. A bottom-up proteomics approach has been applied for the structural characterization of metallated proteins and the data were analyzed in both the positive and negative ion mode. The negative ion mode was achieved after the post-column addition of an isopropanol solution of formaldehyde that enabled sample ionization at micro-flow rates. The negative ion mode MS has been proved to be beneficial for the analysis of binding sites on ruthenated protein in terms of ion charge reduction and consequent simplification of target sequence identification based on isotopic differences between ruthenated and non-ruthenated peptides. Moreover, the negative ion mode ESI MS shows the advantage of singly charged ion formation and, unlike MALDI MS, it does not cause complete ligand fragmentation, merging the benefits of each method into a single experiment. Six target sequences were identified for the binding of en and dach compounds, and four sequences for the binding of bipy. All compounds have been found to bind histidine and one aspartate residue. Docking studies showed that the identified sequences are the constituents of five distinct binding sites for en and dach, or two sites for the bipy complex. The selection of binding sites seems to be dependent on the chelate ligand and the form of the complex prior or after hydrolysis of the leaving chloride ligand.
