The organic material will be anaerobic decomposed by methane bacteria when municipal solid waste (MSW) is processing in landfills, thus methane will be emitted to the atmosphere.

城市固体废弃物(MSW)在填埋处理时，甲烷菌将使废弃物中的有机物质发生厌氧分解，从而会有甲烷排放到大气中。

However, the methane-oxidizing bacteria and anaerobic cellulose-decomposing bacteria were found high in quantity, and SRB low in quantity at the outer edge of the gas field.

气田外缘甲烷氧化菌、厌氧纤维素分解菌数量较高，而硫酸菌还原菌较低。

First, the hog waste is placed in an anaerobic digester, which contains bacteria that consume the manure and release methane gas.

Methane is the final product of the anaerobic metabolic pathway of clostridium bacteria breaking down organic matter in the absence of oxygen, primarily cellulose.

Anaerobic microbes--bacteria that live without oxygen--were generating the methane.
