Results: Bacterial metabolism nearly ceased after the formation of a sealed environment and when the substance gradient occurred, bacterial metabolism tended to be vigorous. 伴随着封闭环境的形成,细菌代谢近乎停止;伴随着浓度梯度的出现,细菌代谢趋于旺盛。
An antagonistic bacterial strain B21 was isolated from the leaf, could produce large amount of antimicrobial substance, which inhibited the growth of Botrytis cinerea Pers. 本研究以从植物叶片上筛选出的具有强烈抑制番茄灰霉病生长并产生大量颉颃物质的颉颃细菌B21为实验材料。
Methods Observing resistance of different bacterial strains to chemical disinfectants by suspension quantitative germicidal test, bacterial strains with higher resistance were selected to study the effect of organic substance with different concentration on disinfection. 方法采用悬液定量杀菌试验,观察不同菌株对化学消毒剂的抗力。选择抗力较高的菌株,观察在不同浓度有机干扰物存在时对消毒效果的影响。
Co-immobilized Algal-bacterial to Remove Nutrient Substance of Municipal Wastewater 共固定化菌藻对市政污水中氮磷去除的研究
Factors such as different bacterial species, different bacterial carriers and organic substance can influence the germicidal efficacy of plasma. 不同细菌种类,不同染菌载体以及有机物等因素均影响等离子体杀菌效果。
For observing the resistance of clinically isolated gonococcus and the standard bacterial strain to chemical disinfectants, standard strain with relatively high resistance was selected to carry out organic interfering substance test. 观察临床分离的淋球菌和标准菌株对化学消毒剂的抗力,选择抗力较高的标准菌株作有机干扰物试验。
Clinical common resistant bacterial strains and calf serum were used to perform organic substance influence test. 以临床常见的耐药菌株为代表菌,小牛血清为有机物进行有机物影响试验。
Meanwhile, using biological bacterial manure also increase the content of soluble solid substance, eggplant red element and VC, changing it's taste, improved the quality of products. 同时,施用微生物菌剂还可显著提高番茄可溶性固形物、茄红素和Vc含量,改善产品风味,提高农产品品质。
Experiment on Inducing Anti bacterial Substance from Silkworm Eggs 家蚕卵抗菌物质的诱导
The domesticated bacterial can use the mineral as the energy substance more easily, so the sluggish time decreased, and the leaching rate was higher than that of original bacterial. 采用驯化细菌浸出,浸矿细菌能以矿物作为速效能源基质,缩短了生长迟滞期,浸出速度比原始细菌浸出有显著提高。
Biomembrane consists of bacterial and extracellular polymeric substance ( EPS), which can attach to the surface of the implant and form a highly organized multicellular structure, which is the protective growth pattern of bacterial. 可附着在植入物表面形成一种高度组织化的多细胞结构,是细菌的保护性生长方式。
