Title
Stereoselective hydroxylation of ethylbenzene to (R)-1-phenylethanol using mycelia of Aspergillus niger as catalyst
Abstract

The mycelia of Aspergillus niger MTCC-404 have been shown to act as a biocatalyst for the transformation of ethylbenzene to (R)-1-phenylethanol in 99% enantiomeric excess. 72% of the products are (R)-1-phenylethanol. The conversion yield is dependent on pH, temperature and mycelia concentration in suspension. A. niger MTCC-404 facilitates methylbenzene transformation to benzylalcohol, and propylbenzene to 1-phenylpropanol. Therefore, A. niger serves as a biocatalyst for hydroxylation of alkylbenzene's benzylic position.
