土壌に存在する糖質分解酵素の種類とその起源

抄録

Since it is made to be the index which clarifies biological activity or metabolism activity of the general soil, type and quantity of the carbohydrate-degrading enzymes were measured on several organisms and the soil. The high and active β-N-acetylglucosaminidase was included for mold, mushroom, congograss, Japanese black pine seed and root black pine. In addition, the high activities of the enzyme also existed in the soil in which congograss and black pine grew. Therefore, β-N-acetylglucosaminidase existing in the soil is considered with the enzyme in which mold, mushrooms or plants produce intermingles. Then, biological activity and metabolism activity seem to be generally high for the soil of which this enzymatic activity is high. In the growth soil of congograss and black pine, the principal enzyme was the β-glucosidase, and the especially high value in the enzyme except for the β-N-acetylglucosaminidase was shown. This enzyme also existed for the myceria of Aspergillus and fruit body of mushroom. Because the β-glucosidase was few for the root of the congograss and black pine the β -glucosidase of the soil in which congograss and black pine, grew derive from other source. Therefore, there is the high possibility that the mold which lives in the soil accumulates β -glucosidase in this soil.
