Abstract

The microbial transformation of racemic diisophorone was investigated using the plant pathogen Aspergillus niger as a biocatalyst. Incubation of diisophorone with Aspergillus niger gave 8α‐hydroxy‐diisophorone, 10‐hydroxydiisophorone and 17‐hydroxydiisophorone on the basis of their spectroscopic data including two‐dimensional NMR analysis, nOe and an X‐ray crystallographic study. The antifungal activity of diisophorone against Aspergillus niger was also examined. Copyright © 2004 Society of Chemical Industry

No intracellular enzyme possessing milk-clotting activity was found in the mycelium of Aspergilha niger. There was a time-lag in the clotting stage on using small amounts of the culture filtrate in the reaction mixture. Dilution of milk caused a decrease in the milkclotting activity and this was att
