大肠杆菌

Objective:To express Tropic1808 gene in Escherichia coli .

目的：在大肠杆菌宿主系统中表达Tropic1808基因编码的蛋白。

The expression efficiency of codon-optimized amyFF was increased by 12 times in Escherichia coli.

其中的amyFF在大肠杆菌中表达量提高了12倍。

Objective To clone and express thanatin mutant in Escherichia coli and purify it.

目的：在大肠杆菌中克隆表达thanatin突变体蛋白并纯化。

Objective: To express and purify human interleukin-10（IL-10） in Escherichia coli.

目的：在大肠杆菌中表达和纯化人白细胞介素-10（IL-10）。

The change of outer membrane permeability in Mar strains of Escherichia coli plays an important role in multiple drug resistance.

外膜 通透性的改变是大肠杆菌产生多重耐药的机制之一。

What is special about is that it kills bacteria such as typhoid, salmonella, Escherichia coli and cholera from the water.

什么是特别的是，杀死细菌，如伤寒，沙门氏菌，大肠杆菌和霍乱，从水。

Antibacterial activities of the three synthesized compounds against Escherichia coli and Staphylococcus aureus were observed.

同时观察了合成的这3种化合物对大肠杆菌和金黄色葡萄球菌的抑菌活性。

A bacteriocin-like substance producing strain T12 was screened from 212 lactic acid bacteria isolated from intestine of healthy pigs by paper disk test and was identified as Lactobacillus. The supernatant of T12 exhibited strong inhibitory activity against the gram-positive bacteria, including Micrococcus lysodeikticus, Staphylococcus aureus, Bacillus subtilis and Bacillus cereus. A strong activity was also observed against the gram–negative bacteria and some eumycete, such as Escherichia coli, Salmonella typhimurium and Fusarium graminearum.

通过滤纸片法从健康肉猪猪大肠、小肠中分离得到212株抗生物质产生菌，以杯碟法复筛，得到1株对溶壁微球菌、金黄色葡萄球菌、枯草芽孢杆菌、蜡状芽孢杆菌等革兰氏阳性菌和大肠杆菌、鼠伤寒沙门氏菌等革兰氏阴性菌以及部分真菌如禾谷镰刀霉均有强烈抑制作用的乳酸菌。

Observation under Transmission Electron Microscope was carried out and growth curve of E. coli was ploted out. It was indicated that PSPPs might change the permeability of cell membrane, make cell excrescent and inhibit cell division.

透射电镜观察和大肠杆菌生长曲线表明，该色素的抑菌作用可能是通过增强细胞膜的通透性，使细胞异常生长，抑制对数生长期的细胞分裂，使细胞质稀薄、细胞解体。

The TEM analysis indicated that the proper growth of the filament and fimbrial morphology were MrkD adhesin dependent.

而藉穿透式电子显微镜来观察这些重组大肠杆菌表现的纤毛，我们发现mrkD基因型的变异会影响第三型纤毛的长度和型态。

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％。
