土壤微生物群落 meaning in English
phytoedaphon
Examples
- Soil quality - determination of abundance and activity of soil microflora using respiration curves
土质.用呼吸曲线测定土壤微生物群落的个丰度和活性 - It is well known that more than 90 % of the microorganisms existing in nature are refractory to selective enrichment cultures . to overcome these drawbacks , molecular biological techniques especially 16s rdna analysis are increasingly employed in the analysis of microorganisms in their natural habitats
目前已知，自然环境中的微生物有90 - 99是还未能培养，为了克服上述缺点，分子生物学技术尤其是16srdna分析的方法引入土壤微生物群落的分析。 - At the same time , the result of the functional diversity of soil microbial community indicated that soil microbial metabolism quotient ( awcd ) , microbial community richness and shannon index all decreased significantly in red soils polluted by cadmium and lead compared with non - polluted soils . these results suggested the structure of microbial community have changed , decreased the functional diversity of microbial community , and reduced the microbial number utilizing different carbon resources
Biologgn测试结果显示，镉、铅污染红壤微生物群落代谢剖面( awcd )及群落丰富度、多样性指数均显著低于非污染土壤，表明重金属污染引起了土壤微生物群落功能多样性下降，减少了能利用有关碳源底物的微生物数量、降低了微生中义摘要物对单一碳源底物的利用能力，最终导致土壤微生物群落功能多样性发生变化。 - The respiratory intensity of the contaminated soil decreased by 29 . 93 % while ammonification and nitrification increased significantly than that of control soil . 2 . extraction and purification of soil microbial total dna a method of extracting soil total dna was developed , and it can extract dna from g + bacteria
二、土壤微生物总dna的提取和纯化方法研究为了采用不依赖于培养的16srdna分析的方法研究有机磷农药长期污染对土壤微生物群落结构的影响，建立了从土壤中提取总dna的方法，并通过改进使适合于对革兰氏阳性菌的提取。 - The diversity of organophasphate pesticides degrading bacteria and the convention of the degrading genes in organophasphate pesticides polluted soil confirmed the horizontal transfer of degrading genes , revealing the molecular mechanism of the adaptation of soil microbial community to the organophasphate pesticides pollution
有机磷农药污染土壤中降解菌的多样性以及降解基因的保守性，证明了降解基因在污染土壤细菌间发生了水平转移，揭示了土壤微生物群落适应有机磷农药污的分子机制。
