CELLULASE PREPARATION CONTAINING ENDOGLUCANASES DERIVED FROM TWO DIFFERENT TYPES OF MICROORGANISMS

摘要

By having a cellulase preparation contain at least a fixed amount of endoglucanases derived from two different types of microorganisms, the preparation can be imparted with higher activity and broader pH characteristics than cellulase preparations containing the microorganisms individually. Further, by introducing the two types of different cellulase genes into the same host cell and having said genes express simultaneously, it is possible to easily produce a cellulase preparation having high level of activity and broad pH characteristics.
