Abstract

Polypropylene glycol (PPG)-assimilating Sphingobium sp. strain PW-1 was grown on 0.5% PPG 700. PPG and its metabolites were analyzed by MALDI-TOF mass spectrometry. An oxidized form of a terminal alcohol group appeared with each molecular species as a metabolite. Cell-free extract showed PPG dehydrogenase activity. In this way, the oxidative metabolic pathway for PPG was confirmed.
