Advances in the Researches of Soil Microbe by Isothermal Microcalorimetry

土壤微生物是陆地生态系统中分解者亚系统的主要组成部分,参与了包括有机质降解、营养转化、植物生长的促进或抑制以及各种土壤物理过程在内的一系列反应活动.土壤微生物则是土壤质量重要的生物指标,可以用来监控土壤质量的变化.等温微量热法是一种简便、快速地测量微生物活性的方法,在土壤微生物代谢热效应的研究领域中广泛应用.就等温微量热法在土壤微生物活性中的研究进展进行综述:等温微量热法的简介,微量热方法与传统方法的比较,等温微量热法在各种外界环境和土壤条件影响下的土壤微生物活性研究中的应用,并对等温微量热法在土壤微生物和其它方面的研究进行了展望.

Soil microbe is the major part of the decomposers in the continent ecosystem. As well it takes part in several physiologic activities including the decomposition of organic matter, the conversion of nutrition, the stimulation or depression of plant growing, and also all kinds of physical processes in soil. Microorganisms are really important bioindicators of soil quality, and thus they can be used to monitor the changes of soil quality. Isothermal microcalorimetry is a convenient and rapid technique to determine microbial activity, and so it is extensively applied in the measurement of the thermal effect produced by soil microbial metabolism. This article is an overview about the development of isothermal microcalorimetry used in the researches of soil microbial activity. It can be divided into the following parts that are the introduction of the isothermal microcalorimetry, comparison between the isothermal microcalorimetry and conventional methods, study of the influence of many different environmental factors and soil conditions on microbial activity in soil system. And in this overview, the future tendency in soil microbial activity determination and other studies by isothermal microcalorimetry were also discussed.
