Acetone production by methylobacteria

Abstract

An accumulation of acetone was observed during the metabolism of ethane and products of ethane oxidation by washed suspensions of Methylosinus trichosporium OB3B. This strain possessed an acetoacetate decarboxylase and 3-hydroxybutyrate dehydrogenase, and a decline in poly-β-hydroxybutyric acid occurred under the same conditions as acetone formation. A pathway of acetone production from poly-β-hydroxybutyric acid via 3-hydroxybutyrate and acetoacetate was suggested.
