查询词典 nitric bacteria

The bioassay results showed that the quaternary ammonium salt had a good intihtion against typical microorganisms such as heterotrophic bacteria,ammonifying bacteria,denitrifying bacteria and nitrosation bacteria with its inhibition rate was above 90%. Inhibition of the quaternary ammonium salt to fungi and sulfate reducting bacteria was above 85% after 30 min. Inhibition of the quaternary ammonium salt to black mold was about 84% after 30 min,and the to algae was totally inhibited after 24 h.

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。

The nitric oxide released process of nitrosyl metalloporphyrins in vitro was detected with diazotization assay at room temperature, the four nitrosyl metalloporphyrinsbCo-NO、bFe-NO、a_(Co-NO、a_were good nitric oxide donors, the nitric oxide released efficiency is attained about seventy percent.

Positive nerve fibers are in pedal nerve cords and visceral nerve cords. There are no neuronal nitric oxide synthase or inducible nitric oxide synthase positive cells or fibers in the nervous system. A few of endothelial nitric oxide synthase strongly positive nerve cells are identified in pedal ganglia and visceral ganglia. Weakly positive cells and nerve fibers of eNOS can be seen in all of the ganglia and nerve cords.
