Calrorimetric Studies on the Ability of Organic Matter Decomposition by Microbes in Different Kinds of Soils

摘要

Using calorimetric method, heat evolutions associated with the growth of soil microbes (growth thermograms) during microbial decomposition of added organic maters (yeast extracts) in various kinds of soils were studied. Soils tested were soils from vegetable garden, from mountain area, from a playground, from tea garden and sea sands from beach. From the actual heat evolution curves (f(t) curves) derived from the growth thermograms, the :apparent growth rate constant (μ')" of soil microbes was determined.
