菌栖的

Marine microorganisms could be classified as seawater,sediment,commensal,symbiotic and deepsea groups.

海洋微生物研究依据分离菌的生境来源可分为海水、沉积物、共栖、共生和深海菌群。

Under their theory, it is in these biofilms in the appendix, well positioned to avoid pathogens in the rest of the gut, that commensal bacteria take refuge.

按照他们的理论，正是这些阑尾中的生物薄膜给共栖菌提供了一个避难所，因为阑尾在人体内的有利位置使共栖菌避免受到其他肠道病原体的侵袭。

In the pelagic subsystem,there are 4biological state variables which were represented by functional groups:flagellate,diatom,pelagic bacteria and zooplankton.In the benthic subsystem,there were 5 biological state variables represented also by functional groups:macrobenthos,meiobenthos,aerobic and anaerobic bacteria,and shrimp-which is actually epibenthos.

将浮游亚生态系又划分为4个功能群，分别为：鞭毛藻、浮游硅藻、水体中细菌和浮游动物，将底栖亚生态系划分为5个功能群，分别为大型底栖动物、小型底栖动物、底栖厌氧菌、底栖好氧菌，对于营底上生活的对虾也划分在这一亚生态系中予以考虑。

The structure gene pelA from Thermotoga maritima MSB8 encoding pectate lyase was amplified and ligated into pHsh, resulting pHsh-pelA. Through structural optimization on pHsh-pelA, the ultimate plasmid, pHsh-pelC, which possessed the most appropriate structure and free energy of mRNA, was obtained.

将来源于极端嗜热菌属海栖热袍杆菌Thermotoga maritima MSB8的编码碱性果胶裂解酶的结构基因pelA与新型热激质粒pHsh连接，得到重组质粒pHsh-pelA，运用mRNA二级结构预测软件对pHsh-pelA的翻译起始区的二级结构进行优化，得到了具有最佳mRNA二级结构及自由能的质粒pHsh-pelC。

Saprolegniales An order of the OOMYCOTA containing aquatic or soil-dwelling funguslike microorganisms, e.g.

水霉目：为藻菌纲、卵菌亚纲中的一个目，包括水生和部分土栖种类的真菌样微生物。

The results showed as follows: there was a certain limitary role of specific amino acid default on the growth of R.amylophilus, B.fibrisolvens and P.ruminicola.

结果表明：特定氨基酸缺省对嗜淀粉瘤胃杆菌、溶纤维丁酸弧菌和栖瘤胃普雷沃氏菌的生长限制性作用有所差异。

To obtain thermostable xylose isomerase, the gene xylA from an extremely thermophilic bacterium,Thermus thermophilus HB8 was cloned and its product was overexpressed in Escherichia coli BL21(DE3) with expression vector pET22b.

为获得具有高热稳定性的木糖异构酶，运用基因工程技术，从嗜热栖热菌Thermus thermophilus HB8中克隆到嗜热木糖异构酶基因xylA。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
