查询词典 microorganisms

Indirect harm Cockroach carries a variety of pathogenic microorganisms such as bacteria, virus, protozoon, parasitic ovum and fungi, etc.

蟑螂能携带多种细菌、病毒、原虫、寄生虫卵、真菌等病原微生物。

The main mechanism of nitrogen in wetland systems is the action of microorganisms,while the removal efficiency will increase with the protraction of HRTin wetland,and also the action has a close relationship with the alternant changes of DO formed by the undee flowing.

湿地系统除氮的主要机制在于微生物的作用，随停留时间的延长湿地系统对氮的去除效率增加，且该作用与波形水流状态所形成的溶解氧交替变化有关。

Fermentation is a decomposition action on carbohydrate materials; putrefaction relates to the general action of microorganisms on proteinaceous materials.

发酵作用是对碳水化合物的一种分解作用；腐败作用则涉及微生物对蛋白性物质的全面综合的作用。

Kojic acid [2-hydroxmethyl-5-hydroxy-γ-pyrone] is a kind of metabolite produced by some microorganisms.

曲酸是微生物产生的一种具有抗菌作用的弱酸性代谢产物，自古存在于酱类与酒类的酿造中。

Breeding technology of industrial useful microorganisms was developed from conventional mutation and screening technology to mutagenesis breeding ,cross reeding,metabolic control breeding,gene engineering breeding and so on.

工业有益微生物的育种技术已从常规的突变和筛选技术发展到诱变育种、杂交育种、代谢控制育种和基因工程等。

In purplish soil, the number of dominant microbial populations in the rhizosphere was greater than in the other two soils, and the population diversities of bacteria and actinomycetes were even greater and more constant, suggesting that the community structures of microorganisms in neutral purplish soil were more reasonable than in both yellow earth and yellow rendzina, which was probably related to the low incidence of tobacco bacterial wilt in the neutral purplish soil.

烤烟根际微生物的种群多样性及其变化在不同土壤中表现也不一样，相对于黄壤和黄色石灰土，在中性紫色土中，根际微生物的优势种群数目较多，根际细菌和放线菌种群更具多样性，而且较稳定，表明其群落结构更为合理，这可能与中性紫色土上的烟草青枯病发生率较低有一定关系。

The sum of BCOD of BODst test and XH measured through batch respirometer is consistent with the BCOD of BODlt test and the ratio between them was in the range of 0.88-1.02 with average 0.94. The BODlt test is time-consuming and the microorganisms'population and their metabolic characteristic are different from that of the actual activated sludge process. So the respirometry has the advantage of time-validity and representation for the actual activated sludge system.

6呼吸测量法测得的BCOD明显小于长期BOD测试方法的结果，这是由于后者得到的BCOD包括所有的活性微生物COD组分；短期BOD测试得到的BCOD与异养菌COD之和与长期BOD测试得到的BCOD比较接近，两者之比在0.88-1.02之间，平均值为0.94；长期BOD测试耗时长，测试用的微生物种群及其代谢类型都与实际活性污泥过程明显不同，因此，从测试结果的时效性和代表性方法考虑，短期BOD测试更具优势。

Inhibition to activated sludge process by 2-naphthol was also investigated by Warburg respirometer to verify the conclusion drawn from Rank Cell respirometer test. 2-Naphthol in low concentration was biodegradable, hence resulted in the acceleration of respiration, while in higher concentration 2-naphthol would dramatically inhibit microorganisms respiration on account of high K〓 and electron density.

用Warburg呼吸仪研究了2-萘酚对活性污泥过程的抑制作用，验证了RankCell呼吸仪的研究结论，发现低浓度下2-萘酚自身能被生物降解而使活性污泥中微生物呼吸速率升高；浓度增加后2-萘酚因良好的脂溶性和强亲核能力而对活性污泥过程产生强抑制。

After ultraviolet radiation disinfection of the effluent from WWTP,microorganisms can revivify due to the photoreactivation effects.

污水厂出水经紫外线消毒后在排放过程中会出现微生物的复活现象，为此考察了采用UV—氯和UV—过氧乙酸控制光复活的效果。

The rhizosphere is the narrow region of soil that is directly influenced by roots and associated soil microorganisms.

根际微生物是指在植物根系直接影响的土壤范围内生长繁殖的微生物。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
