摘要:
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 7 alpha hydroxylation on 3 beta-hydroxy-Delta(5)-steroids, 6 beta, 12 beta, and 15 alpha hydroxylation on steroidal-4-ene-3-ones, side-chain degradation on 17 alpha,21-dihydroxypregnene-3,20-diones, and 15 alpha hydroxylation on estrone. Both strains were shown to perform redox reactions on alcohols and ketones. (C) 1999 Elsevier Science Inc. All rights reserved.
