title: Enhancement of inulinase production by Aspergillus niger van Teighem.
abstract: Aspergillus niger van Teighem, a soil isolate, was mutagenized by u.v. light. A mutant strain with 3 times increased productivity was generated on exposure of the parent strain to u.v. for 15 min. This mutant on further exposure to u.v. yielded second generation mutants with only marginal increase in inulinase productivity with respect to the parent mutant, but the best yield of 377 U ml-1 was considered promising for industrial use.
