The biotransformation of ethylbenzene to (R)-1-phenylethanol in 97% enantiomeric excess and 67% yield using fungal mycelia of Aspergillus flavus MTCC-9609 has been reported. The mycelia also transform propylbenzene to (R)-1-phenylpropanol in 100%enantiomeric excess and 100% yield. Methylbenzene is converted to benzylalcohol in 97% yield. Thus the mycelia of A. flavus MTCC-9606 hydroxylate atleast methylbenzene, ethylbenzene and propylbenzene at the benzylic positions hydroxylation of which are not convenient by chemical routes.
