Microbial Transformation of Terpenoids. I. Indentification of Metabolites Produced by a Pseudomonad from Citronellal and Citral

Maharashtra Association for the Cultivation of Science, Research Institute, Poona 4, India

ABSTRACT

A bacterium capable of utilizing citronellal or citral as the sole source of carbon and energy has been isolated from soil by the enrichment culture technique. It metabolizes citronellal to citronellic acid (65%), citronellol (0.6%), dihydrocitronellol (0.6%), menthol (0.75%), and 3,7-dimethyl-1,7-octane diol (1.7%). The metabolites of citral were geranic acid (62%), 6-methyl-5-heptanoic acid (0.5%), 3-methyl-2-butenoic acid (1%), and 1-hydroxy-3, 7-dimethyl-6-octen-2-one (0.75%).
