Three groups of biochemical mutants (<em>leucine</em>, <em>tryptophan </em>and <em>arginine</em>) were obtained. Ema and 7 <em>leucine </em>mutants were used to evaluate whether mutation has any considerable effect for the production of such enzyme. Enzymatic activity was expressed as International Unit (IU). It was found that <em>N. crassa </em>mycelia secrete xylanases to the culture supernatant. Mutant Y10 showed highest xylanase activity (1.663 IU) and wild <em>N. crassa </em>(Ema) showed lowest (0.416 IU) activity.</p> ER -
