A process for the saccharification of celluloses is provided. More particularly, a solution obtained after the degradative saccharification of cellulosic materials with cellulases is separated into a liquid portion containing saccharides and a solid matter. Cellulases are recovered from said liquid portion containing saccharides, while said solid matter is treated with an aqueous pH-buffered solution, or an aqueous solution, alcoholic aqueous solution or aqueous pH-buffered solution of polysaccharides or oligosaccharides, or aqueous or aqueous pH-buffered solution of alcohols to recover the cellulases in the solid matter. With the use of this solid matter, newly added cellulosic materials are degradatively saccharified in an aqueous solution or the above-mentioned solutions.
