Biotransformation Of Cis/Trans 3,7-Dimethyl-2,6-Octadien-1-Ol Mediated By Saccharomyces Cerevisiae

Biotransformation of geraniol and nerol mediated by Saccharomyces cerevisiae was performed. Linalool and geraniol were mainly obtained from nerol using growing cells but only isomerisation to geraniol occurred using resting cells. Reductive biotransfomation of geraniol to citronellol was apparently...
