查询词典 microbial

Inoculating the three protozoa reduced soil microbial biomass C. But corn straw decomposition was not decreased, even increased when inoculating Colpoda cucullus. The protozoa, in particular, Colpoda cucullus also had some effects on N and P transformation.

向土壤接种原生动物，虽然减少了土壤微生物生物量，但却促进了玉米秸秆分解，还对土壤有效磷含量、氮素转化产生显著的影响，其中Colpoda cucullus效果最明显。

Influence of phenanthrene on change processes of culturable microbial populations, and the enzyme activities in submerged paddy soil were studied using traditional incubation method.

本文全面探讨了菲污染对淹水稻田土壤的微生物生态毒性效应并分离到两株菲降解细菌，对其进行了鉴定以及系统发育研究，同时进行了降解特性和降解基因克隆及表达方面的研究，为建立有效的菲污染预警指标体系和菲降解微生物的有效利用提供有益的参考。

Culturable microorganisms provide very limited information on soil microbial diversity,because only 0.1%-10% of soil microorganisms can be cultured under conventional laboratory conditions.

传统的基于培养的研究方法只能反映土壤中少数(0.1%～10%)微生物的信息，而大部分微生物目前还不能培养，因而这部分微生物资源尚难以被有效地开发利用。

Experimental results showed that the microbial immobilization could sustain longer decolorization periods than ones of suspended culture system.

由实验结果显示，固定化系统，可维持较久的脱色能力。

Different kinds of flocculants have different capabilities. The flocculants produced by Aspergillus parasiticus is not steady for heat. The flocculating effect is best at acid conditions, and it is not acute for Ca〓. The flocculant can decolorize soluble dyestuff, even the active gorgeous red X-3B which is difficult to be decolorized, the decolor rate is 62. 1%. The flocculant produced by A-9 is steady for heat. It can flocculate Gaolin suspension well without synergistic effects of CaCl〓, and the dose is only 0.05ml/L. The obvious character of A-9's medium cultured for 3days is very viscosity, and viscosity is a mark for microorganism producing microbial flocculants.

不同的微生物絮凝剂具有不同的性能，寄生曲霉产生的絮凝剂对热不稳定，在酸性条件下絮凝效果好，对Ca〓不敏感，该絮凝剂对可溶性染料具有良好的脱色性能，即使是最难脱色的活性艳红X-3B，脱色率也达到62.1％。A-9产生的絮凝剂对热稳定，絮凝高岭土悬浮液时用量小，仅为0.05ml/L，且不需添加CaCl〓等助凝剂，明显优于其它微生物絮凝剂。A-9菌株培养3天的培养液的明显特征是粘性高，试验发现培养液的粘性与微生物絮凝剂性能有较好的对应关系，因此培养液的粘性可以作为微生物产生絮凝剂的重要标志。

PCR-DGGE analysis indicated that the diversity of the microbial community structure was slightly reduced resulting in an optimized one. The dominant genera were Desulfovibrio and Desulfomicrobium .

PCR-DGGE种群结构分析表明，与接种菌源相比，种群丰度略有降低，群落结构得以优化，优势菌群为脱硫弧菌属和脱硫微菌属。
