BIOMETHANATION
■ Biomethanation/Methanogenesis upsc : Methanogenesis/ biomethanation is the formation of methane by microbes known as Methanogenesis . Organisms capable of producing methane have been identified only from the domain Archaea , a group phylogenetically distinct from both eukaryotes and bacteria , although many live in close association with anaerobic bacteria. • The production of methane is an important and widespread form of microbial metabolism . In anoxic environments, it is the final step in the decomposition of biomass . Methanogenesis is responsible for significant amounts of natural gas accumulations, the remainder being thermogenic. • In an all India coordinated project, efforts are on to produce bio-gas for kitchen use and quality manure for fields using bio-methanation of rice straw. • Six domestic level paddy straw-based bio-gas plants have been installed in Punjab. •Organic material is microbiologically ...
