产生细菌的

These five strains were identified as Bacillus cereus、Acinetobacter calcoaceticu、Pantoea agglomrans、Pseudomonas putida and Pantoea ananas by 16S rDNA gene sequence phylogenetic analysis, respectively. These bacteria species is the first reported in oilseed rape rape.

Comparing 20 strains of the PSB in the study, R. azotoformans Y6 was chosen for producing the most lycopene output, which is 8.02×10~(-3) mg/L. Then the effects of pyridine, Triton-x100 Span-20,β-ionone, Isonicotinic acid hydrazide was studied.

利用上述获得的光合细菌类胡萝卜素提取方法和检测方法，对实验室保存的光合细菌菌株产生番茄红素能力进行了比较，得到了番茄红素产生量较高的菌株R.azotoformans Y6，其番茄红素产量为8.02×10~(-3)mg／L。

Commonly,office with air-condition lacks of natural airiness,people breathe out CO2,the fog that is coursed by smoking,some office equipment.These things emante maleficence to bulk in the office.There are wet resorting in the air-condition system,this becomes the "dirt-hiding place".Computers,displays,hand-holding telephone and other electric equipments can produce certain amount of ionization radialization.Some building materials also release certain injurant.

带空调的办公室一般缺乏自然通风，人们呼出的二氧化碳、吸烟产生的烟雾、某些办公设备散发的有害气体积聚其中；空调系统里有水分滞留，成为某些细菌、霉菌病毒的"藏污纳垢"之地；电脑、显示器、手持电话及其他电子设备均产生一定剂量的电离辐射；有的建筑材料本身也释放某些有害物质。

The new findings appear to represent the first known case in which spore formation—also known as vegetative reproduction—depends on the presence of ano the r organism.

研究小组之前的工作曾显示，这种细菌在真菌对水稻幼苗表现出来的毒素方面起到了关键的作用：细菌产生了一种造成幼苗枯萎的植物毒素。

Based on principle of pollen abortion, utilizing tapetum of anther cell, mitochondria of tapetum, callose well, process of cell meiosis during formation process of pollen, we adopt genetic transformation to create plant male sterility, such as, exogenous cytotoxin gene, chaperones, anti-sense RNA, degradation of callose ahead of time, disturbing information intercommunion between mitochondria and nucleolus and affected development of pollen sporule by bacteria.

根据花粉败育的原理，利用花药细胞绒毡层、绒毡层线粒体、胼胝质壁、细胞减数分裂过程等花粉形成过程中的不同环节，采取外源细胞毒素基因、分子伴侣、反义RNA技术、提早降解胼胝质、扰乱线粒体与细胞核之间的信息交流和细菌影响花粉小孢子发育等策略，使花粉不能正常形成，从而产生不育花粉，达到产生雄性不育的目的。

As part of theirnatural digestion process they produce methane; they chew the cud, they have asecond stomach, and inside that stomach there's bacteria that break downcellulose in grass to release energy.

他们在消化过程中会产生甲烷，他们咀嚼反刍的食物，而第二个胃里的细菌会分解植物的纤维素，释放其中的能量，该过程即所谓的厌氧程序，在无氧状态下进行，而所产生的甲烷大多经由打嗝释放。

Cultures from environmental surfaces yielded an average of 12.7 colonies with a range of 1 to 80, while cultures from armpits and groins yielded colonies of bacteria "too numerous to count."

周围物品表面的细菌培养形成的克隆数从1至80不等，平均12.7个；而腋窝及腹股沟的细菌培养所产生的克隆数却&数不胜数&。

Compared with contrasted, the wound healing rate of treatment remarkably improved after 7 days, 14 days, 21 days and 28 days; The histology filleting indicated that the BC could permit the fibroblast and blood capillary to gradually grow into the cellulose pellicle, which interpreted that the BC had therapeutical effect on the skin wound. At last the study of embedding BC under derm indicated that there was no obvious sign of acute immune rejection, slight inflammatory response inducing the organic which lasted short time and gradually extincted till last.

皮下埋植细菌纤维素膜的实验结果表明：细菌纤维素膜植入体内后，未发现明显的排斥反应，早期诱发机体产生的炎症反应轻微，但持续时间短，到后期完全消退。

When the platform of screening β-lactamse inhibitor is constructed,it can not only be used to find new compounds for treating bacteria which resist β-lactam antibiotics, but also be used to screen inhibitors of hydrolase or modifying enzyme which is related to drug resistent bateria.

通过建立β-内酰胺酶抑制剂筛选的平台，不仅为寻找治疗β-内酰胺类抗生素耐药菌开辟一条新途径，并且这一新方法也适用于筛选与细菌耐药有关的其它一些由细菌产生的水解或修饰酶的抑制剂。

Two outstanding fusants SR-7 and SR-T19 were chose out in the fusion group 90-11×FR-008, the former produces not only antibiotics the parents produced but also a new antibiotic effective gainst a wide range of both gram positive and negative bacteria, which the parents could not produce, and its product of the 37℃ fermentation was very effective against the cotton seedling damping off caused by Rhizoctonia sonali while product of the 26℃ was effective agaist the bacterial rots of turnip and Chinese cabbage; the latter have a much stronger activity against a wide range of fungi and yeasts than the parents.

在90-11×FR-008融合组合中，筛选获得2个优良融合子SR-7和SR-T19，前者除产生亲本产生的抗生素外，还产生亲本不产生的一种新的具有广谱抗细菌活性的碱性水溶性抗生素，防病试验表明，其37℃发酵产物对棉花苗期立枯病具有良好的防治效果，28℃发酵产物对萝卜和大白菜具有明显的防腐作用；后者与亲本FR-008的抗菌谱完全一致，但其活性强度都超过了FR-008；采用RAPD分子标记技术检测了SR-7和SR-T19与亲本的同源性及彼此间的差异，从而首次直接从DNA分子水平上验证了链霉菌的原生质体融合子及其遗传重组的多样性。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
