所以一些科学家就在垃圾填埋场进行实地挖掘调查。他们在垃圾填埋场发现了许多叫做巴氏甲烷八叠球菌的产甲烷生物，简称。
So scientists did some digging, literally, to investigate. They found a particularly hearty methanogen called named Methanosarcina barkeri, or just M. barkeri, that can survive at low pH levels.
利用甲醇、H_2+CO_2或乙酸盐作为碳源和能源，从池塘的沉积物取样，经过反复的富集和分离，得到了甲烷八叠球菌的纯培养物。
Samples from pond sediments were inoculated to obtain the pure culture of Methanosarcina sp. by repeated enriching and isolating. Growth was fasted on H_2+CO_2 or methanol.
结果表明，以AM 4为包埋剂对甲烷八叠球菌进行固定化可得到较好的效果。
The results indicate that AM4 is the best entrapment media for Methanosarcina immobilization.
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。
According to the literature, sarcina is one of the methanogen that can produce methane in high performance. The remaining of sarcina will apparently improve methane production.
第二格室，甲烷杆菌为优势菌群，还有少量的球菌，丝状菌几乎没有；
In the No. 2 compartment there are a great many bacillus, little coccus, no filamentous fungus.
