Webb1 juli 2007 · Abstract. The accumulation of storage lipids during the biodegradation of 2,6,10,14-tetramethylhexadecane (phytane) by Mycobacterium ratisbonense strain SD4 grown under nitrogen-starved conditions was investigated. Detailed chemical analysis of intracellular metabolites revealed the existence of (at least) three different pathways for … WebbPhytane in oils is assumed to be mainly a diagenetic product of the phytol side-chain of the ubiquitous plant pigment, chlorophyll. Pristane may be derived from several sources in addition to phytol. Isoprenoids containing fewer than 19 carbons are rare in the biomass and consequently are derivatives of pristane, phytane, or higher molecular weight …
