Secondary fermenters:key organisms in the conversion of complex organic materials to methane (espacially the H2-producing fatty acid-oxidizing bacteria).23、List two syntrophic microorganisms and describe a bit.

乙醇发酵菌发酵乙醇产生H2和乙酸，产甲烷菌消耗利用乙醇酵解菌产生的H2，总反应为产能反应，产甲烷菌不能直接利用乙醇。

A combination analysis of SIP and in situ microbiological methods was applied on the anaerobic digestion of biomass organics suffering from severe acids inhibition. The studies found that accumulated acids were degraded mainly by Methanosarcina firstly with acetoclastic pathway and then with hydrogenotrophic pathway under mesophilic condition, whereas acids were mainly degraded to methane by the tandem reactions of syntrophic acetate oxidation and hydrogenotrophic methanogenesis under thermophilic condition.

联合应用稳定同位素表征技术和微生态原位表征方法，对高浓度有机酸胁迫条件下的生物质类有机物厌氧发酵甲烷化途径的研究结果表明，面临高浓度有机酸迅速累积的环境，中温发酵条件下，优势菌种为甲烷八叠球菌，依时间次序，通过乙酸发酵和氢营养型途径利用累积的有机酸产生甲烷；而在高温条件下，有机酸则通过乙酸氧化和氢营养型甲烷化途径的串联反应被降解。
