By having a cellulase preparation comprising at least a certain amount of endoglucanases derived from two different types of microorganisms, the cellulase preparation can be provided with a higher activity and a wider pH property than those of cellulase preparations each containing one of the endoglucanases alone. Moreover, by introducing and expressing simultaneously two different types of cellulase genes in a single host cell, a cellulase preparation having a high activity and a wide pH property can be produced easily.
