查询词典 amonifying bacteria

Some strains of the nematode-bearing bacteria were bioassayed for their parasitism. All these bacteria can totally not grow or grows badly on the media incorporating the extracts of pine trees, indicating some substances existing in the trees will harmful to the bacterial strains, which is further convinced by preliminary inoculation showing that single bacterial species will not infect Pinus thugbergii. Hence, the growth and reproduction of the nematode-carrying bacteria, which could produce toxic substances causing the death of the tree cells, is closely related to the nematodes, when they first enter to the trees. In the same time, the activity of bacteria improved the circumstances for which nematodes are living, which in turn will beneficial to the growth of nematodes. Thus, there is a complicated interaction among nematodes, bacteria, and pine trees.

对松材线虫携带的细菌的部分菌株进行了寄生性测定，表明这些细菌在添加松树提取液的细菌培养基中不能生长或基本不能生长，这说明松树体内可能存在某些不利于细菌生长的物质，同时初步的接种试验证实，单独的细菌接种不能感染健康的黑松，因此，线虫携带的致病细菌在最初进入树体时，其生长和繁殖与线虫密切相关，结合细菌产生的毒性物质可造成黑松细胞死亡的情况，说明细菌的生长与线虫有关，同时，细菌的活动改变了线虫在松树内的生长环境，使环境变得有利于线虫的生活，因此，线虫、细菌和松树三者存在着复杂的生物关系。

Results indicate that the number of bacteria grown in media LB, CSEA and WSA was 14.84×10^7, 10.27×10^7 and 6.91×10^7 CFU per gram dry soil, respectively, after 192 h of incubation. The diversity index of soil bacteria was the highest in WSA, while the lowest in LB. Certain similarity was discovered in bacteria community between the three media, i. e. the Jaccard index was 57.69% between LB and CSEA, 53.13% between LB and WSA and 66.67% between CSEA and WSA. Phylogenetic analysis suggests that the dominant bacterial groups in the soil belong to β-Proteobacteria,γ-Proteobacteria and Actinobacteria. The sequence of 16S rDNA of some OTUs was found to have high homology with Burkholderiaceae bacterium, Rhodococcus and Mycobacterium, so it is presumed that the cells of these bacteria can secrete Resuscitation-Promoting Factors, which may effectively improve culturability of soil microorganisms.

结果表明，LB、CSEA、WSA培养基192h后每g干土获得的细菌数量分别为14.84×10^7、10.27×10^7和6.91×10^7CFU，但微生物多样性指数以WSA为最高，LB多样性指数最低；三种培养基培养的细菌菌群有一定的相似性，LB和CSEA培养基间的Jaccard指数为57.69%，LB和WSA培养基之间为53.13%，而CSEA和WSA培养基的相似性指数达66.67%；16SrDNA测序结果表明，所获得的土壤细菌优势种群在分类方面主要属于γ-和β-变形杆菌以及放线菌亚门，其中某些OTUs中的16SrDNA序列与Burkholderiaceae bacterium、Rhodococcus和Mycobacterium属具有较高的同源性，推测其细胞能够分泌复苏促进因子，有效地提高土壤细菌的可培养性。
