The ability of 16 strains of Yarrowia lipolytica to biotransform acetophenone and its derivatives has been studied. Thirteen of these strains were derived from a wild-type strain Y. lipolytica A-101; six had the invertase gene (SUC2) from Saccharomyc

Dehydroepiandrosterone (DHEA) (10) and its five derivatives: testosterone (1), androstenedione (2), 17α-methyltestosterone (6), progesterone (13) and pregnenolone (14) were subjected to microbial transformation by the filamentous fungus Didymosphaer

α-Tetralone and β-tetralone were subjected to biotransformation by 14 fungal strains. Enantiomeric purity of the products depended on the reaction time. 3-Day transformation of α-tetralone in Absidia cylindrospora culture gave S-(+)-1,2,3,4-tetrah

Enantiospecific microbial reduction of bicyclic ketones was described. Racemic Wieland–Miescher (1) and Hajos–Parrish (2) ketones were used as substrates. In a 4-h biotransformation of Hajos–Parrish ketone (2) using the strain of Didymosphaeria

Biotransformations of steroid compounds: androstenedione, testosterone, progesterone, pregnenolone and DHEA using Chaetomium sp. 1 KCH 6651 strain as a biocatalyst were investigated. The microorganism proved capable of selective hydroxylation of the

Trichoderma hamatum KCh25 was used to study the mode of transformation of a series of 3-oxosteroids. This potential has not been previously examined. The strain promoted 1-dehydrogenation, which have been rarely observed in fungi cultures. The metabo
