大肠杆菌

Secondly, the genomic DNA is extracted from Zostera marina L. and then amplified by PCR with two oligonucleotide primers synthesized to obtain the partial nucleotide sequences of the Na~+/H~+ antiporter gene. The Na~+/H~+ antiporter gene clone was obtained after a series of manipulation: purificatioin of PCR product, ligation and transformation of recombinant plasmids, blue-white selection and so on. DNA sequence analysis shows that its DNA sequence is highly homologous with the genomic DNA sequence of E.

其次，通过提取大叶藻基因组DNA，根据设计的简并性引物进行PCR扩增，纯化PCR产物，连接，重组质粒转化，蓝白斑筛选等操作，并测序，提交测定序列到NCBI进行BLASTN，结果表明：该序列与大肠杆菌的基因组序列相似性较高，而与其它物种的Na~+/H~+逆向转运蛋白基因没有相似性。

In this experiment,the conditions of breaking cell-wall of E.coli, extraction techniques of aspartic acid 1-C decarboxylase and the cell's zymologic Properties were studied.

本论文研究了大肠杆菌的破壁条件、天门冬氨酸α-脱羧酶的提取条件及其细胞的酶学性质，并将其纯化。

The 12 representative HVRls were back-translated into corresponding nucleotide sequence according to the E. coli favorable condon respectively.

按照大肠杆菌表达外源基因的优势密码子，人工合成了12条代表性HVR1的基因的寡核甘酸片段。

According to the amino acid sequence of monellin and the bias in coden choice in Escheria coli,a single chain monellin gene was synthesized and subcloned into a Escheria coli expression vector pET-28a.

根据已报道的单链Monellin甜蛋白的氨基酸序列，按大肠杆菌基因偏爱密码子，设计和人工合成了单链monellin基因。

Through dietary choices, therefore, humans may expose themselves to an increased risk of infection with the E. coli bacteria and simultaneously sensitise themselves to the potentially lethal actions of the toxin it produces.

因而，由于食谱的选择，人们更易被大肠杆菌感染，同时也对它所产生的可能致命的毒素更加敏感。

And neither particularly has an advantage over the other in surviving the next million years. Actually, some pessimists give E. coli 100-to-1 odds on outliving humans, even though E. coli can currently live only in our guts.

不管是现代人类还是大肠杆菌，都是进化的幸存者，是经历了亿万年淘汰后胜利的佼佼者。

The results that CK was pulled down by bacteria and agglutinated with bacteria indicated that CK bind to bacteria directly.

Far-western blotting和Co-IP试验证明了大肠杆菌通过OmpA，OmpX，OmpW三个外膜蛋白和CK直接结合。

Because the blobs attract bacteria and viruses, including E.

因为这些黏液团吸引细菌和病毒，包括大肠杆菌。

For example, in certain cases of food poisoning caused by bacteria, say E.coli, clostridia or salmonella, the bacteria produce a toxin that damages epithelial cells.

比方说，一些由细菌所引起的食物中毒事件，像是大肠杆菌、肉毒杆菌或是沙门氏菌会分泌出伤害上皮细胞的毒素。

Chemist Sid Nelson, Ph.D., and colleagues, of the University of Washington in Seattle, tested the effects of acetaminophen and caffeine on E. coli bacteria genetically engineered to express a key human enzyme ( cytochrome P450 3A4 ) in the liver that detoxifies many prescription and nonprescription drugs.

化学家学会纳尔逊博士和同事，在西雅图华盛顿大学的，经测试的影响，对乙酰氨基酚和咖啡因对大肠杆菌基因工程表达的一个关键人力酶（细胞色素p450 3a4 ）在肝脏中说， detoxifies许多处方和还敦促毒品。

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％。
