Abstract: An object is to provide a mutant of a cellulase-producing microorganism which produces a cellulase capable of preferentially producing a cello-oligosaccharide during the selective production of the cello-oligosaccharide through enzymolysis of a cellulosic material in the presence of the cellulase, a method for producing the cellulase and a method for producing a cello-oligosaccharide using the cellulase. The present invention relates to a mutant of a cellulase-producing microorganism, in which cellobiohydrolase and β-glucosidase genes are disrupted.
