The below mentioned article provides a note on methanogenesis. Methane producing prokaryotes are a group of archaea which are capable of reducing carbon dioxide or low molecular weight fatty acids to produce methane. The methanogens are strictly anaerobic active at redox potential between - 350 and - 450 mv. They can use CO2 as an electron acceptor. They reduce CO2 [...]

In this article we will discuss about the unique characteristics of cell membrane of archaea. A unique characteristic of Archaea is the presence of ether linkages in the lipids of their cytoplasmic membranes which distinguishes archaea form eukaryotes and most bacteria. The structure of cytoplasmic membranes of many archaea is a lipid bilayer composed of glycerol diether lipids which is [...]
