An inoculum of microbial consortium containing live microorganisms is described. More particularly, the enviro-tolerant methane-producing microbial consortium and a method for the production of biogas having high methane content from organic wastes and biomass slurries are described. The microbial consortium of the present disclosure produces stable biogas production without any seasonal variation impact.

Microbial consortium for enhancing the methane production from feedstock

The present disclosure relates to a process for producing linear alpha olefins in high yield carried out by oligomerization of ethylene in the presence of a novel catalyst composition. The catalyst composition includes Zirconium compound, an organoaluminum compound, and at least one Lewis base selected from cyclic and acyclic ethers (i.e., di-n-butyl ether and diethyl ether). The process for oligomerization of ethylene is carried out in an inert organic solvent in the presence of said catalyst composition. The process as disclosed herein provides significantly high activity of the said catalyst composition resulting in high yield of the alpha olefins (>95 wt. %) as the product and significantly minimum polymer as by-product. The process provides higher yield of C6-C10 fraction with >60 wt. %.
