Screening and Identification of High-yield Strain for 2-Phenylethanol

Abstract:

Abstract A strain designated as SH003 with high 2-phenylethanol tolerance and bioconversion properties was selected from 24 yeast strains with different sources. It could grow in the medium containing 4g/L 2-phenylethanol. Under the optimized conditions, the production and productivity of 2-phenylethanol respectively reached to 4.31g/L and 0.18g/L/h. The molar conversion rate of L-phenylalanine to 2-phecylethanol was 72.4%. Identified by the morphological and physiological characteristics and its 18S rDNA sequence, strain SH003 was closely related with Saccharomyces cerevisiae on phylogenesis.
