10. 近年来厌氧氨氧化细菌和氨氧化古菌的发现，提示环境中氨氧化过程及其微生物驱动者的复杂性。
Until recently, the findings of anaerobic oxidizing (anammox) bacteria and ammonia-oxidizing archaea (AOA) indicate that ammonia oxidation and the prokaryotes participate in this process are complex.
Methane-producing archaea (methanogens) are a type of chemolithotroph that can use carbon dioxide and hydrogen to make methane without ever seeing the sun.
Recently, living cells - many of which are Archaea from the Pyrococcus and Thermococcus genera - were found in a mud core taken from 1.6 km below the sea floor off the coast of Newfoundland.
As to importance, when originally identified as distinct, the archaea, too, were regarded as marginal-yet their methane-generating properties are now a factor in climate-change calculations.
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?

15. 这种古生菌是迄今为止发现的最小的生物体中的一种。
The individual archaeans are some of the smallest organisms ever found.
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.

17. 虽然，像细菌一样，古生菌也没有细胞核，但是它们与你我这样的真核生物具有其他共同的特性。
While, like bacteria, archaeans don't have a cell nucleus, they share other traits with eukaryotes like you and me.
In water acidic enough to dissolve metal, archaeans form biofilms that researchers call "blanket strips" because they look like pink fiberglass insulation.
A study published this month in Environmental Microbiology describes a "giant" archaean that grows to 3 centimeters long and is nearly visible without magnification (it's just 0.1 mm thick).

But this doesn't mean there are no viruses that affect the Archaea.
youdao
22. 古生菌还具有完全与细菌和真核生物不同的细胞膜。
Archaeans have cell membranes that are completely different from both bacteria and eukaryotes.
Perhaps Archaea has been relegated to its seemingly second-class status because it is a relatively recent discovery—the separate domain was first proposed in 1977.
youdao
24. 但是将古生菌归在细菌这个类别下面，在生物学上便讲不通。
But lumping Archaea in with Bacteria simply doesn't make biological sense.
The researchers who first identified them, led by Jill Banfield, have found other enigmatic features such as mysterious tubular structures whose function is not yet known.
