title: Synthesis of steroidal lactone by penicillium citreo-viride.
abstract: The biotransformations of a series of steroids by the fungus penicillium citreo-viride A.C.C.C. 0402 have been investigated, and the conversion to the same product testolactone (1) was observed from progesterone (2), dehydroepiandrosterone (3), 4-androstene-3, 17-dione (4), 5-androstene-3, 17-diol (5) with the exception of pregnenolone (6) and 3beta-hydroxy-5, 16-pregnadien-20-one (7). The possible metabolic pathways of the biotransformations were also discussed in the paper and the fungus penicillium citreo-viride A.C.C.C. 0402 was isolated during screening stains from samples collected from Zhengzhou, Henan province of China.
