The application of Penicillium notation genus for biotransformations of steroids has been investigated. The reactions observed include insertion of an oxygen atom into D-ring of steroids, 15 alpha-hydroxylation of 17 alpha-methyl testosterone derivatives, ester bond hydrolysis, and degradation of a testosterone derivatives side chain.Microbial production of testolactones, the biologically active compounds. was also achieved using this strain in up to 98% yield.

of steroid compounds is a promising, environmentally friendly route to new pharmaceuticals and hormones. One of the reactiontypes common in the metabolic fate of steroids is Baeyer-Villiger oxidation, which in the case of cyclic ketones, such as steroids, leads to lactones. Fungal enzymes catalyzing this reaction, Baeyer-Villiger monooxygenases (BVMOs), have been shown to possess broad substrate scope
