Culture substrate composed of cellulose gel, solid medium and cellulase activity assay method using this medium using the same

摘要

This invention improved the fault of the former cellulose gel nutrient medium, the cellulose gel nutrient medium whose visibility of the microbial colony is good, the cellulose gel culture backing material and its production manner in order to produce this, and being quicker, it offers the cellulase production microbe or the screening modulo of cellulase activity whose efficiency is good. As for one feature of this invention, as a nutrient medium solidification component being the culture backing material which consists of the cellulose and cellulose gel which contains with the water, the aforementioned cellulose, the particular cellulose 8% (W/V) it features that it is something where the viscosity in the 26 of the solution which in the dimethyl acetamide which contains lithium chloride is dissolved at the concentration of 2.5mg/mL is 12 - 35mPa S, it is the culture backing material.
