查询词典 complement-fixing

The Cyanobacteria and soil bacteria such as Azotobacter, which carry out BNF without plant involvement, are examples of free-living nitrogen fixing organisms.

兰细菌和土壤细菌如固氮菌都是自生固氮微生物的代表，它们可以在没有植物介入下进行生物固氮。

Hetertrophic nitrogen-fixing bacteria were the species belonged to Azotobacter and Beijerinckia through preliminary identification.

In order to select high nitrogen-fixing azotobacter strains, nitrogenase activity of 13 strains separated in the rhizosphere in Gansu non-leguminous crop fields were measured by acetylene reduction method. Also the fertilization effect of the strains on spring wheat was investigated via pot experiment.

为挑选具有高固氮能力的自生固氮菌菌株，用乙炔还原法对甘肃省春小麦和玉米等非豆科作物根际土壤中分离所得的13株菌进行固氮酶活性测定，并通过盆栽试验对其进行春小麦肥效试验。

Some are in life transitions, among them a baby-faced 50-year-old Silicon Valley engineer, a recently divorced man, who said that the practice of manually fixing his attention on a tiny spot of a woman's body improves his concentration at work.

其中一位50岁却长着娃娃脸的，不久前离了婚的硅谷工程师声称，手动地将自己的注意力集中在女人身体上某一小部位上，这样做有助于提高工作中的注意力。

To better understand the roles of LsrA protein in nodulation, a series of analyses of nodules using scanning electron microscopy, genetic and biochemical approaches have been carried out. Our analyses suggest that the lsrA1 nodules contain bacteroids in the invasion and establishing zone only. The lsrA gene expression is active early in the invasion zone and activated later than bacA genes. The lost of LsrA protein dramatically reduced the expression of nifA and fixK, and completely blocked the expression of the nifH gene for nitrogenase. LsrA protein functions early in the bacteroid development and it is essential for the development nitrogen fixing bacteroids.

前期的工作中，苜蓿中华根瘤菌Rm1021中90个候选LysR基因已经被定向插入突变，并筛选在自生生长时期、共生生长时期的表型，以期寻找更多在自生状态或共生固氮中有功能的LysR转录因子。1 针对前期鉴定出的共生固氮必需的lsrA基因，我们应用了一系列扫描电子显微镜技术、生物化学、分子遗传学等方法，发现lsrA基因主要在根瘤侵染区开始表达，表达时序也在侵染阶段左右，但晚于bacA基因表达；LsrA蛋白缺失后根瘤固氮区中缺乏具有固氮能力的类菌体，nifA和fixK基因的转录水平降低，nifH基因的转录被完全阻断，因此LsrA蛋白为根瘤发育所必需，是新的根瘤发育信号传导途径成员。2 通过表型筛选我们鉴定了苜蓿中华根瘤菌的oxyR基因，并研究了它的调节特性。oxyR突变后，苜蓿中华根瘤菌对过氧化氢敏感性提高，适应性降低。

A few weeks ago, one of my favorite human beings, a handyman in Malibu, was fixing a balky kitchen cabinet door in my house when he told me excitedly about his new car.

数周前，在Malibu的一位杂物工，也是和我一位特别要好的人，在我家修理一扇运动不畅的厨房柜门时，兴奋地谈起了他的新车。

Results: Over 50% cephalic vein patients had complications, about 30% of whose tubes were pulled out in halfway. Less than 10% basilic vein patients had complications, and about 90% of them completed the treatment plan. Two jugular external vein cases had the catheters taken off because of the inappropriate fixing.
