Aspergillus niger was subjected to gamma rays mutagenesis at different dose rates (40 to 120 k.Rads). The mutant strains of Aspergillus niger were isolated and selected by random screening method. The selected mutant derived strains were compared with parent type of Aspergillus niger for enhanced production potential of mutarotase. A mutant strain of Aspergillus niger with maximum production potential of mutarotase was finally selected.
