The anaerobic metabolism of deoxycholicacid by Pseudomonassp. NCIB10590 was studied. The metabolic pathway was similar to that operating under aerobic conditions with 12β-hydroxyandrosta-1,4-dien-3,17-dione as the major neutral product an metabolites which are not produced during aerobic metabolism were isolated and evidence is presented for the following structures: 9α-hydroxyandrost-1-en-3,17-dione

the biotransformation of progesterone by whole cells of Brazilian marine-derived fungi. A preliminary screening with 12 fungi revealed that the strains CBMAI 1996, CBMAI 847, sp. CBMAI 1237, CBMAI1185 and CBMAI 935 were efficient in the biotransformation of progesterone in the first days of the reaction, with conversion values ranging from 75 % to 99 %. The fungus CBMAI1185 was employed in the reactions
