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.
但是这也并不意味着没有病毒可以影响到古生菌。
But this doesn't mean there are no viruses that affect the Archaea.
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.
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.
像其他古生菌一样，这种古生菌的基因组同时与真核生物和细菌的基因组具有一些相似性。
Like other archaeans, their genomes share some similarities with both eukaryotes and bacteria.
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.
这是可以理解的：由于古生菌和细菌的细胞膜都是由类脂分子构成的，所以它们在外形上相似。
And understandably so: Archaea are similar to bacteria in appearance, as both have fat-like molecules that make up their membranes.
所有的生命形式可以划分为三大类：真核生物(包括植物，动物，真菌，以及其他生物)、细菌以及古生菌。
All of life can be divided into three domains: Eukarya (including plants, animals, fungi, and other organisms) Bacteria, and Archaea.
为了研究分析嗜盐古生菌物种与细菌视紫红质(BR)蛋白基因资源，分离纯化得到极端嗜盐古生菌ab3。
In order to study and analyze the species and bacteriorhodopsin (BR) protein resource, a strain of extremely halophilic archaea AB3 was isolated.
但需要特别注意的是：他只是统计了真核生物，也就是那些细胞相对复杂的动物，而把细菌以及古生菌排除在外了。
But there are some important caveats: it counts only the eukaryotes, that is, critters with relatively complex cells.
古生菌被归为不太重要的二等类别，或许是因为它是新近才被发现的——首次提议将古生菌作为单独的类别是在1977年。
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.
一项最新研究显示了古生菌的重要性。为了了解所有的生物，可以将生物划分为三大类，古生菌便是这三大类中的一类生物。
NEW RESEARCH SHOWS THE IMPORTANCE OF ARCHAEA, ONE OF THREE DOMAINS INTO WHICH ALL LIVING THINGS ARE CLASSIFIED, FOR UNDERSTANDING ALL OF BIOLOGY.
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。
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.
在足够溶化金属的酸水中，古生菌形成了一层生物膜，研究人员将这层生物膜称为“红毯带”，因为它们看起来就像粉红色的玻璃纤维隔离层。
In water acidic enough to dissolve metal, archaeans form biofilms that researchers call "blanket strips" because they look like pink fiberglass insulation.
最早识别出这种古生菌的研究者吉尔·班菲尔德(JillBanfield)还发现了其他神秘的特征，比如神秘的管状结构，这种结构的功能目前还不清楚。
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.
这个月发表在《环境微生物学杂志》(Environmental Microbiology)上的一篇研究，描述了一个长到3厘米长的“巨型”古生菌，而且几乎不需要放大就能看见(厚度仅有0.1毫米)。
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).
结果表明，柴达木盆地东部地区古生界有机质多为菌、藻类生源，少数有陆源有机质混入。
The results show that in the eastern Qaidam Basin, the Palaeozoic organic matters were mainly from bacteria and algae, and some Palaeozoic source rocks contained terrestrial bio-inputs.
