One was the pqsA' positive expression plasmid constructed by cloning the pqsA'-lacZ fusion digested from pYHP441 into miniCTX-1, whose sequence was then integrated into wild type PAO-1 chromosome by biparental mating procedure. The other was pqsA-E operon knock-out plasmid whose sequence between pqsD and pqsE operon was inserted by tetracycline cassette by the site specific insertion mutagenesis strategy and the mutant constructed by biparental mating of S17-1 that harbored the plasmid and pqsA' positive expression mutant.

一种是酶切质粒pYHP441获得pqsA'-lacZ片段后，亚克隆入质粒miniCTX-1中，构建成PqsA'的阳性表达质粒，随后将构建的质粒，通过双亲交配过程整合入野生型铜绿假单胞菌株PAO-1染色体组中；另一种是通过点特异插入诱变策略，将四环素基因盒插入启动子pqsD和pqsE之间，构建的阴性质粒转化入大肠杆菌S17-1株后，和上述pqsA'阳性表达突变株进行双亲交配过程。

Ramie fibers contain a "plant antibiotic element", after trimming by isunte ecologic and hygienical process, and inspect by the authoritative disease control center, can control and kill many bad bacteria, such as staphylococcosis, enteric bacilli, blastomyces albicans, and epiphyte arousing skin disease, this is the reason that many western developed countries choose ramie garments to wear.

麻纤维含有一种&植物杀菌素&，且通过-生态保健整理，经权威疾病控制中心检测，能有效地抑制和杀死多种有害菌，如金色葡萄球菌、白色念珠菌、大肠杆菌和引起皮肤病的真菌。这是许多西方发达国家选择着装麻料的重要原因。

ASES is 59% identical to Artemisia cyclase cDNA clone cASC125, 50% identical to epi-cedrol synthase from A. annua, 48% identical to amorpha-4, 11-diene synthase from A. Annua, 39% identical to the 5-epi-aristolechene synthase from tabacco, 38% identical to vetispiradiene synthase from H. Muticus, 41% identical to the δ-cadinene synthase from cotton. The coding region of cDNA was cloned into procaryotic expression vector pET30a and overexpressed in E. coli BL21 (DE3). The cyclase proteins extracted from bacterial culture were found largely in the insoluble protein fraction. The tissue specific expression patterns were analyzed by RT/PCR.

克隆的倍半萜合酶氨基酸序列与烟草马兜铃烯合酶、莨菪岩兰螺旋二烯合酶、棉花杜松烯合酶的一致性分别为39％，38％和41％；与青蒿柏木脑合酶、紫穗槐二烯合酶和一个推测的倍半萜合酶克隆cASC125的一致性为50％，48％和59％。cDNA编码区序列被克隆进原核表达载体pET-30a，并在大肠杆菌BL21（DE3）中诱导表达，但过量表达的蛋白主要是以不溶性蛋白形式存在。

Six piglets of each group were selected on 42-d-old to measure the caecal and colonic microflora population and PH. The result showed that caecal and colon E.

试验开始第7天，每组各随机选6头仔猪，麻醉后剖腹取肠道内容物以测定盲肠和结肠大肠杆菌、乳酸杆菌及双歧杆菌浓度和pH。

By screening on plate, 64 strains of bacteria with antagonism to E.coli were isolated from Rabbit caecum.

本研究旨在从健康兔肠道内分离出一株对大肠杆菌有拮抗活性的菌株，并对其鉴定到属。

The contents of caecum and rectum of 30 healthy broilers were collected by aseptic method.

无菌采取30只健康鸡的盲肠、直肠内容物，以大肠杆菌O_8为宿主，从这些样品中分离到一株能裂解其它细菌的细菌。

Coli.Methods The cDNA encoding CP was amplified by RT-PCR using the mRNA extracted from premature Carica papaya as a template,and inserted into vector pET22-b.

方法从生番木瓜中提取mRNA后进行反转录，得到木瓜凝乳蛋白酶的cDNA，PCR产物克隆到pET22-b载体中，重组质粒转化至大肠杆菌BL21，进行诱导表达及表达产物的检测。

Of special interest is a suigeroxide dismutase[7] from E.Coli which contains Mnat an unknown binding site and redox catalyses the disproportionation of O2 to yield O2 and H2O.
