Alkaline cellulases named K-64, K-19, and K-520; microorganisms of the genus Bacillus producing these alkaline cellulases; and each process for producing them are disclosed. The alkaline cellulases have an optimum pH range at an alkaline region and are stable at a wide pH range. The enzymes of the present invention are not adversely affected by the addition of detergent components such as surfactants, proteases, chelating agents, and the like, and, accordingly, can effectively be used as a detergent component.
