Abstract

The formation of alcohols from amino acids during surface culture of Cladosporium cladosporioides No. 9 in a synthetic medium has been studied. In this investigation the authors found that not only alcohols but also their acetates were remarkably much produced in culture solution when amino acids were added in a synthetic medium including either glucose or ethanol or acetic acid as a carbon source. Thus, isobutyl alcohol and isobutyl acetate were produced from L-valine, isoamyl alcohol and isoamyl acetate from L-leucine and β-phenylethyl alcohol and β-phenylethyl acetate from L-phenylalanine, respectively.
