WebAnaerobic bacteria survive in a broad range of temperatures, but there are two broad categories of methanogens. Medium-temperature (mesophilic) bacteria thrive between 20 and 45 °C (68 and 113 °F), and anaerobic digestion using mesophilic bacteria takes place between 30 and 38 °C (86 and 100 °F). WebDec 16, 2024 · Biogas is a combustible gaseous fuel that is collected from the microbial degradation of organic matter in anaerobic conditions. Biogas is principally a mixture of methane (CH 4) and carbon dioxide (CO 2) along with other trace gases. Biogas can be collected from landfills, covered lagoons, or enclosed tanks called anaerobic digesters.
