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.

现在，许多科学家把早期造成地球变暖的大部分原因归结于厌氧微生物——产甲烷菌——它产生了温室气体甲烷。

Many scientists now attribute much of the warming of early Earth to oxygen-intolerant microbes—methanogens—that produce the greenhouse gas methane.
