Lipase Activity Enhancement by SC-CO2 Treatment
Original language description
The activity of lipases from porcine pancreas, Candida antartica recombinant from Aspergillus oryzae, Candida cylindracea (immobilized), Penicilium roqueforti, Aspergillus niger, Rhizopus arrhizus, Mucor miehei (two types of immobilization), and Pseudomonas cepacia (two types of immobilization) was studied after using them as biocatalysts of blackcurrant oil hydrolysis under SC-CO2 conditions. The reaction was performed at 40 degrees C and 15 MPa in a continuous-flow reactor. Increased relative activityof all used lipases after the hydrolytic reaction was observed. The most remarkable increase in the activity was noted for the lipase from Rhizopus arrhizus which was increased by more than 50 times. The highest activity was shown by Lipozyme (R), lipase from Mucor miehei immobilized on macroporous resin. Both treated and untreated Lipozyme(D were used as biocatalysts in hydrolytic resolution of the racemic cis- or trans-isomers of 2-(4-methoxybenzyl)cyclohexyl acetates. Satisfactory re

Zvýšení aktivity lipas účinkem superkritického oxidu uhličitého
Czech description
Byla studována aktivita lipas z vepřového pankreatu, mikrooorganismů Candida antarctica, Aspergillus oryzae, Candida cylindracea, Penicilium roqueforti, Aspergillus niger, Rhizopus arrhizus, Mucor miehei a Pseudomonas cepacia jako katalyzátorů hydrolýzyoleje z černého rybízu za podmínek v superkritickém oxidu uhličitém. Byl objeven vzrůst hydrolytické aktivity všech lipas.
