大肠杆菌

Methods: Thirty extracted human molars whose pits and fissures on the occlussal surface had been inoculated with Escherichia coli were randomly divided into three groups: group A was treated with newly confected phenol-formaldehyde resin which resinified the dental fissure contents, group B was sealed Bis-GMA resin in pits and fissures and group C as the control group was only treated by cleaning.

选择30颗人离体磨牙，在咬合面点隙裂沟接种大肠杆菌，随机分为3组；A组以新配制的酚醛树脂使点隙裂沟内容物树脂化，B组以成品Bis-GMA封闭剂作点隙裂沟封闭，C组仅进行表面清洗作为对照组；各组分别沿裂沟点隙处片切牙齿，放入LB培养基培养，观察大肠肝菌生长情况。

A 16 copy gene was gained and induced to express in E.coli under the driver of P RP L promoters regulated by the temperature sensitive repressors.

将目的基因首尾串联，制备得到的16拷贝基因在温控启动子PRPL调控下于大肠杆菌中获得表达。

The replicon of irp-2 gene was identified by PCR method in 64 of 67 strains (95.5%) hybridized with irp-2 probe.

鉴于在一部分肠侵袭性大肠杆菌中可检测到irp-2基因，因而检测了EIEC的侵袭性基因ipaB基因。

The pZW contains one E. coli replicon and one resistance gene. The length is reduced by 2530bp.

该载体具有一个大肠杆菌复制子，一种抗性基因，比pZMW载体小2530bp。

2The total living bacteria quantity in the fermented feedstuff was close to thecontrol(P＞0.05),but the coliforms and putrefying microbe were inhibited infermented feed by EM.

1EM中的优势菌群为乳酸杆菌，其次是酵母菌；EM发酵饲料中的优势菌也为乳酸杆菌，大肠杆菌、腐败菌受到明显抑制；EM能增加粪便中乳酸杆菌数量，降低沙门氏菌的检出率。

Gene coding for matrix protein (p15) of donkey leukocyte attenuated vaccine strain of equine infectious anemia virus was cloned from its proviral DNA obtained from the vaccine strain infected donkey leukocyte cultures,and expressed in E.coli.

从感染驴白细胞的马传贫驴白细胞弱毒疫苗株前病毒DNA中克隆了编码基质蛋白(p1 5 )的基因，并在大肠杆菌中进行了表达。

By splicing in genes from other bugs, the company was able to engineer synthetic metabolic pathways—ones that do not exist in nature—that enable the bacteria to produce isoprene from the sugars found in plant materials such as sugar cane, corn cobs and switchgrass, a tall-growing variety native to North America.

Genencor的科学家们通过将大肠杆菌的基因与其它菌类基因接合，则能研发出前所未有的代谢合成途径，使细菌能从植物所含的糖类中制造出异戊二烯，这些含糖植物包括甘蔗、玉米棒和北美特有的变异品种柳枝稷等。

Nursing Biqing disinfection fluid, is the world's a better health care products, the use of efficient broad-spectrum disinfectant as a major food-grade raw materials, of such as E. coli, Staphylococcus aureus, Candida albicans, mold, fungi and other bacteria propagule to kill a significant role.

碧清消毒护理液，是目前世界上较为理想的卫生护理产品，采用高效广谱食品级消毒剂作为主要原料，对如大肠杆菌、金黄色葡萄球菌、白色念珠菌、霉菌、真菌等细菌繁殖体有显著杀灭作用。

To explore the biological function of propeptide, NK, pro, pronattokinase and active site-mutated proNK genes were cloned and overexpressed in E.

为研究pro肽的生物学功能，我们分别在大肠杆菌中表达并纯化了pro肽、proNK、Ser221Ala proNK、NK。

In contrast, deletion of the propeptide yields mature but inactive NK, the inclusion bodies of NK or denatured rNK couldn't be renatured in any condition, but with the aid of exogenously purified propeptide or Ser221Ala proNK, the inactive mature protein could be renatured by an intermolecular pathway in vitro.

此外，我们利用融合基因表达系统在大肠杆菌中高效表达了谷胱甘肽S-转移酶／NK和硫氧还蛋白／NK两种融合蛋白，经体外复性、纯化，均获得活性蛋白。以上结果显示，pro肽在体内体外，通过分子内或分子间的方式均能帮助NK分子的折叠与再折叠，作为一种分子内的分子伴侣，pro肽为NK分子正确折叠所必需。

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％。
