AB  - Organska geohemija je multidisciplinarna nauka koja kombinuje aspekte analitičke organske hemije i hemije prirodnih proizvoda sa aspektima geologije, petrologije i okeanografije u praćenju sudbine organskog materijala u različitim delovima geosfere tokom geološke istorije.
Jedna od naznačajnijih oblasti ove nauke je primena geohemijskih tehnika u ispitivanju naftnih basena. U tom cilju koriste se analize biomarkera i aromatičnih ugljovodonika za određivanje porekla i maturisanosti, karakterizaciju depozicione sredine, utvrđivanje stepena biodegradacije i u korelacijama nafti kao i nafti i njihovih pretpostavljenih izvornih stena. Svi ovi rezultati, kombinovani sa rezultatima geoloških i geofizičkih analiza pružaju značajne podatke na osnovu kojih se mogu proceniti preostale rezerve, predvideti buduća proizvodnja nafte i gasa i poboljšati ukupna eksploatacija ispitivanih naftnih basena.
Cilj ovog rada bio je da se na osnovu detaljne analize biomarkerskih jedinjenja tipa n-alkana, izoprenoidnih alifatičnih alkana, sterana i hopane, utvrdi poreklo, paleosredina taloženja, stepen maturisanosti stratigrafska pripadnost nafti iz naftnog polja Rus koje se nalazi u srpskom delu Panonskog basena. Nafte su primenom hromatografije na mikrokoloni razdvojene na tri frakcije, zasićenu, aromatičnu i polarnu (NSO), na osnovu čega je određen grupni sastav. Za analizu bioloških markera u zasićenoj frakciji korišćena je gasna hromatografija sa masenom spektrometrijom.

AB  - Phenol and amino groups were introduced into alginate to different degrees via oxidation with 2.5, 5, 10, 15 and 20 mol% of periodate and reductive amination by tyramine. Modification of alginate with tyramine was confirmed by FTIR spectroscopy and UV-VIS spectroscopy, while concentration of phenol and ionizable groups was determined using absorbance at 275 nm and acid-base titration. All tyramine-alginates were able to form hydrogels after cross-linking with horse radish peroxidase (HRP) and hydrogen peroxide. Tyramine-alginates oxidized with up to 10 mol% of periodate were also capable of forming hydrogels with calcium ions. Tyramine-alginates were tested for HRP immobilization within micro-beads obtained by peroxidase catalyzed droplet polymerization using internal delivery of hydrogen peroxide via glucose oxidase and glucose. Highest activity of immobilized peroxidase was obtained with 20% (w/v) tyramine-alginate obtained via 20 mol% periodate oxidation. Immobilized enzyme was not leaking from the micro-beads and was further kinetically characterized for pyrogallol oxidation. Km for pyrogallol was increased after immobilization from 1.93 mM for soluble HRP to 734 mM for immobilized HRP. The optimum pH was also increased from pH 7.0 to 8.0. Temperature and organic solvent stability improved significantly after immobilization, so that half-life at 70 degrees C increased around four times, while half-life in 80% (v/v) dioxane increased 22 times. After repeated use of 6 times in batch reactor for pyrogallol oxidation immobilized HRP retained 45% of original activity.
