铁素体抗菌不锈钢在与大肠杆菌的作用过程中，能破坏大肠杆菌的细胞壁和细胞膜，使其形体逐渐消瘦，同时伴有组织液流失；在与金黄色葡萄球菌的作用过程中，金黄色葡萄球菌的形体更快地缩小。

Sequence structure of a cloned gene is an important factor to determine its expression level in E.coli. In this paper, we studied the expression of a fragement of HIV-1 gp120 gene and a fragement of choler toxin A subunit gene in E.coli using a new expression strategyoptimizing the gene sequence as a whole.

外源基因的序列结构是影响外源基因在大肠杆菌中表达的重要因素，我们采用基于"外源基因全序列结构优化"的新的表达策略，研究了HIV-1 gp120-801和霍乱毒素A亚单位(CTA-246)基因在大肠杆菌中的表达情况。

The structure of the Schiff base was characterized by FTIR and XRD spectroscopy,which confirmed that the amino groups in chitosan have been reacted with citral to form the Schiff base.

对大肠杆菌、金黄色葡萄球菌和黑曲霉的抗菌实验表明，该产物对大肠杆菌、金黄色葡萄球菌和黑曲霉的最低抑菌浓度分别为1 g/L、1 g/L和5 g/L，其抗菌活性随浓度的增加而增加，且优于壳聚糖。

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.

Genecor的科学家们将其它细菌的基因拼接到大肠杆菌上，从而在大肠杆菌上制造出一种自然界中不存在的代谢物合成途径。它使细菌能从植物材料中的糖分生产出异戊二烯——这些含有糖类的植物包括甘蔗、玉米芯，还有原产于北美洲的高个儿品种柳枝稷。

Finally, silver nanoparticles resulted in the leakage of cytoplasmic component. Moreover, the analysis of agar gel electrophoresis demonstrated that silver nanoparticles could increase the decomposability of genome DNA.

另外，纳米银对大肠杆菌总DNA影响的分析表明，随着纳米银浓度的增高，大肠杆菌总DNA样品降解的程度增大。

Results Ganmaofang had definite bacteriostatic action on standard strain of staphylococcus aureus and escherichia coli, and clinical dissociative strain of staphylococcus aureus, escherichia coli, klebsislla pneumoniae, Staphylococcus epidermidis, Staphylococcus intermedius, Staphylococcus simulans and beta streptococcus in vitro. Its MIC is between 0.075 g/mL and 0.2 g/mL. Ganmaofang could prolong the survival time of mouse infected by staphylococcus aureus and decrease the mortality of ill mouse, meanwhile it could enhance the survival rate of mouse infected by pneumoniae diplococcus.

结果感冒方体外对标准菌株金黄色葡萄球菌、大肠杆菌和临床分离菌株金黄色葡萄球菌、大肠杆菌、肺炎克雷伯菌、表皮葡萄球菌、中葡萄球菌、溶葡萄球菌、乙型链球菌具有一定的抑菌作用，MIC 0.075~0.2 g/mL，体内可延长金黄色葡萄球菌感染小鼠的存活时间和减少感染小鼠的病死率，对肺炎双球菌感染小鼠可提高感染小鼠的存活率。

Furthermore, the results of the antibiotics sensitivity test of 38 isolates to 24 kinds antibiotics show that all isolates have presented antibiotic resistance disparately as well as multi-resistance. All isolates are sensitive to Cephalosporins antibiotics and Aminoglycosides antibiotics such as Amikacin, Cefazolin, Cefradine, Cefoperazone, and Ceftriaxone. Thirty-eight isolates are extremely resistant to Penicillins antibiotics, Lincomycins antibiotics, Tetracyclines antibiotics and Macrolides antibiotics such as Midecamycine, Lincomycin, Carbenicillin, Tetracycline, Amoxicillin and so on. Antibiotics sensitivity test provides guidance for antibiotic application and scientific foundation from poultry farms.

按世界卫生组织推荐的Kirby-Bauer菌液涂布法对38株大肠杆菌进行24种抗生素的药物敏感性试验，结果表明：38株大肠杆菌均有不同程度的耐药，而且均表现多重耐药；较为敏感的抗生素是头孢菌素类和氨基糖苷类抗生素，其中以阿米卡星、头孢唑啉、头孢拉定、头孢哌酮和头孢三嗪最为敏感；对青霉素类抗生素、林可胺类抗生素、四环素类抗生素和大环内酯类抗生素耐药严重，其中以麦迪霉素、林可霉素、氨苄青霉素、四环素和阿莫西林耐药性最为严重；药物敏感试验为保定、秦皇岛和北京三个地区养鸡业提供科学的用药指南，为药物防治提供科学依据。

The recombinant mouse enterokinase light chain could be well expressed in Ecoli, but most of them were inclusion.

利用pET32a/BL21(DE3)表达系统成功地在大肠杆菌中表达了重组鼠源性肠激酶轻链，表达量约占大肠杆菌BL21(DE3)总蛋白的30%，但多以包涵体的形式存在。

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%.
