The Archaea的意思|示意

The cluster analysis showed that crop type impacts the community structure of soil archaea.

聚类分析结果显示， 作物类型会影响土壤古菌群落结构。

Or are there other biological domains hiding in the shadows—missed, like the archaea were for so long, because biologists have been using the wrong tools to look?

或者是否还有其他的生物“域”隐藏在某个神秘角落？ ——不为人所知，就好像古菌一样，因为生物学家误用观察工具所致，默默无闻多时。

Methane-producing archaea (methanogens) are a type of chemolithotroph that can use carbon dioxide and hydrogen to make methane without ever seeing the sun.

产甲烷古菌（methanogens）是一种化能自养生物，它能利用二氧化碳和氢合成甲烷，而不需要太阳参与。

Researchers hope to shed more light on how these organisms survive in the deep biosphere, but Archaea may also provide insight into life on other planets.

关于这些生物体是如何在深层生物圈中生存的，研究人员希望能够提供更多的线索。

But while bacteria reproduce rapidly, the Archaea population doubles over the course of hundreds, even thousands, of years thanks to a slower metabolism and distinct genetic structure.

尽管细菌繁殖很快，但是由于古生菌新陈代谢较慢，细胞结构截然不同，其数量需要历经几百年甚至几千年的时间才能翻倍。

An archaean converts DNA into proteins very differently from, say, streptococcus-in fact, protein synthesis in archaea is more similar to the human process than to bacteria.

古生菌，比如链球菌，将DNA转录成蛋白质会非常困难——实际上与细菌相比，古生菌的蛋白质合成过程与人类的蛋白质合成过程更相似。
