大肠杆菌

Coli can overproduce 38 000 antigen of Mycobacterium tuberculosis. Inclusion bodies are easy to purify and can protect the recombinant antigen from protease, on the other hand, it has not biological activity unless the denatured protein is accurately folded.

Results showed that 0.01g/mL extract of Oxalis corniculata L. had obvious antimicrobial effect on S. aureus, but all extract of Oxalis corniculata L has not any antimicrobial effect on E.

结果表明，0.01g/ml的提取物对摇床培养的金黄色葡萄球菌生长具有明显的抑制作用；但各种浓度的提取物对摇床培养的大肠杆菌生长均无抑制作用。

Propenediol oxidoreductase isoenzyme is one of the key enzymes in biotransformation systhesis of 1,3-propenediol,and is encoded by the yqhD gene.

大肠杆菌1，3-丙二醇氧化还原酶同工酶被yqhD的基因编码，能催化羟基丙醛生成1，3-丙二醇。

The major route of β-alanine production for pantothenate in Escherichia coli is through the α-decarboxylation of L-aspartate, which is catalysed by the enzyme L-aspartate-α-decarboxylase. The panD mutant of E. coli is β-alanine auxotrophy.

在大肠杆菌中，用于泛酸生物合成的的β-丙氨酸主要是由L-天冬氨酸α位脱羧而产生，这个生化反应由panD基因编码的L-天冬氨酸-α-脱羧酶催化。

The team found that a bacterium called Mycobacterium paratuberculosis releases a molecule that prevents a type of white blood cell from killing E.coli bacteria found in the body.

该小组发现，一种称为结核杆菌的细菌杆菌释放的分子，防止一种白血细胞杀死大肠杆菌中发现的细菌在体内。

Pasteurization, which is often used for milk or waste milk, can be used to reduce bacteria levels and has been shown to be very effective at killing a variety of pathogenic bacteria including Salmonella, E. coli, Mycobacterium avium subspecies paratuberculosis, Mycobacterium californicum, Mycobacterium bovis, and Listeria monocytogenes.

巴氏灭菌常使用于牛奶或牛奶废料，它可以用来降低细菌水平，并已被证明能有效的杀死多种致病细菌，其中包括沙门氏菌、大肠杆菌、副结核分枝杆菌亚种、californicum分枝杆菌、牛分枝杆菌和李斯特菌。

The E. coli ClpQY is an ATP-dependent protease that consists of an ATPase large subunit and a peptidase small subunit. The function of ClpQY protease is as a chaperon in refolding of misfolded peptides and as a protease to catalyse the degradation of abnormal proteins as well.

大肠杆菌ClpQY是一个ATP依赖的蛋白酶，ClpQY蛋白酶包含了具ATPase活性的大蛋白分子和一个小分子的peptidase，ClpQY蛋白酶作为一伴随蛋白质扮演分解错误摺叠的蛋白质，也为一催化分解不正常的蛋白质的蛋白酶角色。

This research successfully constructed an engineered E. coli, which could express the catalase gene perA from Bacillus stearothermophilus under the control of the tac promoter, then the fermentation condition of engineered E. coli and purification, properties of its produce catalase were studied.

本文成功构建在tac启动子控制下表达嗜热脂肪芽孢杆菌过氧化氢酶基因perA的大肠杆菌工程菌，并对其发酵条件、重组过氧化氢酶的纯化及酶学性质进行了研究。
