title: Steroid transformations with Fusarium oxysporum var. cubense and Colletotrichum musae.
abstract: The utility of two locally isolated fungi, pathogenic to banana, for steroid biotransformation has been studied. The deuteromycetes Fusarium oxysporum var. cubense (IMI 326069, UAMH 9013) and Colletotrichum musae (IMI 374528, UAMH 8929) had not been examined previously for this potential. In general, F. oxysporum var. cubense effected 7alpha hydroxylation on 3beta-hydroxy-delta5-steroids, 6beta, 12beta, and 15alpha hydroxylation on steroidal-4-ene-3-ones, side-chain degradation on 17alpha,21-dihydroxypregnene-3,20-diones, and 15alpha hydroxylation on estrone. Both strains were shown to perform redox reactions on alcohols and ketones.
