Abstract
This study was aimed to isolate Aspergillus niger locally and mutagenesis by ultraviolet radiation. The optimal environmental conditions of temperature, pH, incubation period and shaking were studied in order to get the best inulinase productivity. The optimal conditions for the enzyme production was found to be at temperature of 20° C and the pH 4 for 3 day with shaking at 100 rpm. The maximum enzyme activity of 26.82 U/ml was found for D mutant strain.
The inhibition action of the Aspergillus niger strain metabolites including inulinase enzyme was also tested .It was found that there is an inhibition action against pathogenic bacterial species which included, Staphylococcus aureus , Pseudomonas aeruginosa , Klebseilla pneumoniae, Escherichia coli , Proteus valgaris and Citrobacter freeundii.
