Abstract

Biogas is a methane-rich gas produced from microbial digestion of waste (agricultural, sewage, and landfill) which can be used for power production. The low rate of biogas production from an anaerobic digester becomes a problem in cow manure processing increasing. Biogas production is influenced by the biomass of methanogenic bacteria in the conversion of organic matter contained in a digester, so other methanogenic bacteria are needed to accelerate the rate of biogas production, namely methanogenic bacteria from the anaerobic digester of cow manure. Bacterial isolation was carried out by isolating samples of the anaerobic digester of cow manure in fluid thioglycolate media using the pour plate method in a vial tube. Those samples were incubated at 37 ℃ in an anaerobic chamber where after isolation, the bacteria were identified through several biochemical tests. Based on research conducted, a single colony of methanogenic bacteria is gram negative bacterium where the results of the isolates show that the bacteria of the Methanobacterium genus. The highest biogas production was obtained from the addition of 15%v/v of bacterial isolate. It can be seen from the volume of biogas produced with the volume 40 mL for 14 days of the fermentation process.
