Methanotrophic bacteria

Article Abstract:

Methanotrophs are a diverse group of gram-negative bacteria that obtain carbon and energy from methane metabolism. On the basis of utilization of formaldehyde, these bacteria are classified into three groups. The type 1 and type X methanotrophs use the ribulose monophosphate pathway to assimilate formaldehyde. The type II methanotrophs use the serine pathway. The type I methanotrophs grow best in conditions of low methane concentration while the type II grow best in the presence of high methane levels.

Ether polar lipids of methanogenic bacteria, structures, comparative aspects, and biosynthesis

Article Abstract:

About 40 ether polar lipids have been identified in recent years. Polar head groups include ethanolamine, serine, inositol, N-acetylglucosamine, dimethyl- and trimethylaminopentanetetroll and glucosaminylinositol. Glucose is the only hexose identified in most methanogens. Results of chromatography analysis and in vivo studies done were presented to understand better the mechanisms of biosynthesis of the ether lipids.

Biosynthesis of ether-type polar lipids in archaea and evolutionary considerations

Article Abstract:

The review deals the in vitro biosynthesis of the characteristics of polar lipids in archaea along with preceding in vivo studies. It is proposed that common phospholipid polar head groups were present in precells before the differentiation into archaea and bacteria.
