摘　　要：目前已经分离鉴定的产甲烷菌已有200多种,Fe、Co、Ni、Mo、Se,维生素B2,维生素B12等微量元素对其活性有促进作用;然而,无机毒性物质(重金属离子、Na+、K+、pH、氧化还原电位等)、有机毒性物质(硝化物、抗生素、氰化物和氯仿、芳香族化合物等)、氨氮,氮氧化物等对产甲烷菌活性有抑制作用。已建立了产甲烷微生物利用H2/CO2、甲醇和醋酸为基质的产甲烷生化代谢模型,产甲烷菌含有氢化酶、辅酶F420、辅酶M、甲基呋喃、四氢甲基喋呤等独特的酶。Activity of methanogenic organisms which were discovered more than 200 kinds was accelerated by trace elements including Fe, Co, Ni, Mo, Se, vitamin B2 and B12, while the activity was inhibited by inorganic matters including heavy metal, Na^＋, K^＋, pH and redox potential, organic matters, ammonium nitrogen and NOx. Biochemical model of methanogenic organism which uses H2/CO2, methanol and acetic acid as substrate was established. Methanogenic organisms contain hydrogenation enzyme, coenzyme F420, coenzyme M, MFR and H4MTP enzyme
