大肠杆菌

"Ironically, foods rich in Neu5Gc are the most common source of Shiga toxigenic Escherichia coli contamination," wrote the researchers .

研究者们写道：讽刺的是，富含 N -乙酰神经氨酸的食物也是普遍存在大肠杆菌志贺毒素基因。

Most countries with systems for reporting cases of food-borne illness have documented significant increases over the past few decades in the incidence of diseases caused by micro-organisms in food, including pathogens such as Salmonella , Campylobacter and enterohaemorrhagic Escherichia coli , and parasites such as cryptosporidium, cryptospora and trematodes.

大多数国家的制度，报告病例经由食物传染的疾病有显着增加记录在过去几十年中的发病率所造成的微生物在食品，包括病原体，如沙门氏菌，弯曲杆菌和大肠杆菌肠，和寄生虫，如隐孢子虫， cryptospora和吸虫。

Complementary DNA encoding 49KD ES antigen of Trichinella spiralis muscle larvae was cloned in E.coli by recombinant DNA technology.

应用DNA重组技术将编码旋毛虫肌幼虫49KDa抗原的基因克隆于大肠杆菌中。

Results Bamboo Vinegar had obvious anti- bacteria and fungal actions for the trichophyton rubrum .Trichophyton actions,and canida albicans,cryptococcus neoformans,aspergillusfumigatus.

目前国内对竹醋液抗真菌作用的研究相对较多，而对抗细菌的报道较少，主要有大肠杆菌、金黄色葡萄球菌和枯草芽孢杆菌，对这三种细菌的MIC和MBC的测定结果也不一致［3，5］。

Here we report the cloning, expression, purification and activity assay of Phenylalanyl-tRNA synthetase from Trypanosoma brucei in Escherichia coli host.

本研究用大肠杆菌成功克隆表达并纯化了布氏锥虫苯丙氨酰-tRNA合成酶并进行了活性测定。

During the stationary phase of fermentation, cell productivity was slightly reduced. MgSO_4 and tryptone have the positive effect on the product synthesis and cell growth respectively. Based on these conclusions, MgSO_4 and tryptone were added to the feed medium to enhance the production of polysialic acid. Variable feed rate policies were applied to the fed-batch fermentation process and the final biomass and polysialic acid production were both increased by 40 percent.

通过摇瓶实验研究了大肠杆菌发酵过程中菌体生长和产物合成的影响因素，结果表明：产物合成与菌体生长是相耦联的过程，菌体生长受到菌体代谢产物的抑制作用，聚唾液酸的合成不受代谢产物的抑制作用；发酵进入稳定期后菌体的生长和生产能力有所降低；硫酸镁和胰蛋白胨分别对产物合成和菌体生长有一定的促进作用。

ColipET32/IL-11/BL(DE21 recombinant human interleukin-11 in the flask were studied by orthogonal experiment design,including the of culture medium(glucose,tryptone,yeast extract and pH),shaking speed,medium volume and inoculum.

为了探讨发酵条件对大肠杆菌表达人白细胞介素-11融合蛋白的影响，利用正交实验设计，对工程菌的生长条件和人白细胞介素-11融合蛋白表达进行优化。

Coli pET32/IL-11/BL(DE21 that expressed recombinant human interleukin-11 in the flask have been studied by orthogonal experiment design, including the components of culture medium (glucose, tryptone, yeast extract and pH), shaking speed, medium volume and inoculum concentration.

为了探讨发酵条件对大肠杆菌表达人白细胞介素-11融合蛋白的影响，利用正交实验设计，对影响工程菌的生长及重组人白细胞介素11融合蛋白的表达因素如培养基中的葡萄糖浓度、蛋白胨浓度、酵母提取物浓度、无机盐浓度、pH及摇床转速、装液量、接种量等在摇瓶中进行了初步的研究。

An unfused protein was expressed in heat-induced E. coli.

对pBV-ung热诱导后，在大肠杆菌宿主细胞中得到了重组表达产物。

The expression of the unfused protein in the strain E.

将PoIFN-α1a插入到原核表达载体pGRW，转化大肠杆菌DH5α，得到的重组菌株经诱导有以包涵体形式表达的目的蛋白条带出现，表达量约10％。

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％。
