Development of a novel calorimetric method for analyzing microbial properties of soil including VBNC microbes.

发展了一种新的分析土壤微生物功能特性的量热方法，包括VBNC微生物。利用土壤样品直接观测了土壤微生物同化碳源的放热过程，并对土壤样品和碳源的每种组合进行了表征放热过程的量热参数计算。结果表明，通过对这些参数的分析，可以定量地评价土壤微生物的功能特性，如微生物对化学物质的抵抗力和土壤微生物的功能多样性。

A novel calorimetric method for analyzing functional properties of soil microbes including VBNC microbes was developed. Exothermic processes of carbon-source assimilation by soil microbes were directly observed using soil samples as they were, and calorimetric parameters which characterize the exothermic procedures were evaluated for each combination of soil sample and carbon source. It was shown that functional properties of soil microbes, such as resistibility of microbes against chemicals and functional diversity of soil microbes, can be quantitatively evaluated on the basis of the analysis of the parameters.
