title: Regioselective hydrolysis of acetates in the presence of different yeast strains.
abstract: The model compound, hexane-1,2-diol diacetate, was hydrolyzed in the presence of supernatant obtained after cultivation of 4 yeast strains: Pichia jadinii, Rhodotorula glutinis and Yarrowia lipolytica KKP 379 and Saccharomyces cerevisiae 102 to evaluate the type of catalysis. The regioselectivity of extracellular enzymes as a function of hydrolysis towards primary and secondary acetic acid ester groups was monitored. The enzymes secreted by P. jadinii, R. glutinis and Y. lipolytica KKP 379 exhibited high regioselectivity towards primary position, while those from S. cerevisiae showed practically no discrimination between the ester groups.
