The oceans were populated by anaerobic microbes.

海洋中栖息着厌氧生物。

So when we dry the soil, that anaerobic microbial that's living in that soup, that mushy soil, either dies or goes dormant.

所以当我们使土壤干燥时，那些生活在潮土壤中的厌氧生物要么死亡，要么进入休眠状。

Anaerobic organisms make a lot of  gas, so James has learned the hard way to make sure he's keeping track of any  signs of pressure building up in the jar.

厌氧生物会产生大量气体，所以詹姆斯不得不通过实践学会密切关注罐子里任何压力增大的迹象。
