Microbial production of hydroxy and oxo fatty acids by several microorganisms as a model of adipocere formation.

Abstract

Some varieties of aerobic or anaerobic microorganisms from the human stool and adipocere were separated and identified. These separated microorganisms together with other authentic ones produced 10-hydroxystearic acid from oleic acid. Some bacteria could convert oleic acid to 10-oxostearic acid as well as 10-hydroxystearic acid. These findings indicate that the microbial enzyme(s) catalyzes the hydration of oleic acid and probably the oxidation of this hydrated product. Aerobic bacteria as well as anaerobic microorganisms were found to be involved in the formation of adipocere.
