ABSTRACT:
The disclosed in an invention directed to carrying out accurate and easy evaluation of microbial-degradability of organic matters objectively. To carry out a method for evaluating microbial-degradability of an organic matter, an organic matter as an evaluation subject is placed together with a certain prescribed microbial source into a reaction column maintained constantly at a fixed temperature to effect decomposition of the organic matter by microorganisms contained in the prescribed microbial source under feeding of CO.sub.2 -free saturated water vapor into the reaction column and to measure the weight of carbon dioxide formed by the decomposition. A cellulose as a evaluation reference is also decomposed likewise to measure the weight of carbon dioxide formed by the decomposition, and then comparative discussion of these two measured values is carried out so as to evaluate degradability of the organic matter.
