An agar plate isolation technique was developed for screening the mutants of Aspergillus niger. Fungal growth in solid media containing carboxymethylcellulose(CMC) was selected within 2-3 days. The mutants selected by the new technique showed a remarkable enhancement of CMCase, FPase, β-glucosidase, xylanase, and β-xylosidase activities. These results clearly show that the new isolation technique is a practical method for the selection of better strains.
