n.【微】产烷生物
The reactor has some zymogen and acetogen, but no methanogen bacteria. 反应器中有一定量的发酵菌和产乙酸菌，但无产甲烷菌。
The present method in studying the distribution of methanogen is MPN(numbers of methanogen). 目前研究地层中产甲烷菌分布的主要技术方法是地层水中产甲烷菌记数法。
Biogenic gas is the product of methanogen in anaoxic environment.Its formation and occurrence is controlled by the distribution of methanogen. 生物气是产甲烷菌代谢的产物,其在沉积地层中形成及分布预测一定程度上要依赖产甲烷菌分布规律的研究。
During anaerobic fermentation process, the methanogen communities changed noticeably.In initial stage methanococcus predominated, but methanobacterium in end stage. 在沼气发酵过程中，微生物菌群的变化也比较明显，初期以球菌占优势，后期则转为杆菌类为优势菌。
According to the literature, sarcina is oneof the methanogen that can produce methane in high performance.The remaining of sarcina willapparently improve methane production. 根据以往的资料显示，八叠球菌是产气较好的甲烷菌之一，这种菌的驻留会使整个产气效果明显提高。
