纤维素酶酶活测定方法的研究与评价

In order to form a integrated standard for industrialized Cellulase，this experiment analyzed several commonly used enzyme activity test standard such as IUPAC standard, Chinese agriculture industry standard and many enterprises' norms. The results indicated that the enzyme activity measurements of endoglucanases and total cellulase suggested by IUPAC standard were the optimal for the reason of simple operations and favorable stability and repeatability. Furthermore, some domestic enterprises' products were also calibrated and analyzed, this action was conducive for the establishment of integrated industrial cellulase activity test system.
