古生菌

阿尔金山盐湖极端嗜盐古生菌的分离及16Srdna序列分析

Isolation and 16S rDNA sequence analysis of extremely halophilic archaea from Saline in Altun region

虽然从蛋白质合成器官上来看，古生菌在许多方式上与真核生物最为相似；但是古生菌还会与自己身上寄居的细菌共享并交换DNA物质。

Although based on its protein-synthesis apparatus Archaea is in many ways most similar to the Eukarya domain , archeans can also share and exchange DNA with the denizens of the Bacteria domain .

嗜盐古生菌br基因的遗传分析

Genetic analysis of the br gene in halophilic archaea isolated from Xinjiang region

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 .

Rhomboid蛋白家族是近些年来才发现的，已经在古生菌、细菌、酵母菌、蜾蝇、哺乳动物，包括人，甚至植物等生物中都发现了Rhomboid蛋白同源物。

Rhomboid protein family is found in the recent years . We have found the homologue of rhomboid protein in archaea , bacteria , yeast , fruit flies and mammals , including humans , even plants and other organisms .

极端嗜盐古生菌启动子序列缺失突变的微量热研究

Microcalorimetric Study on Deletion Mutagenesis of the Gene Promoter Sequences from the Extremely Halophilic Archaea

回到实验室后，向沉积物输入甲烷，激活了古生菌的生长，以及寄生它们的病毒。

Back in the lab , the sediments were fed methane , which triggered archaea growth - along with their viral parasites .

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 .
