Effect of media supplements and culture conditions on inulinase production by an actinomycete strain.

Abstract:

:Streptomyces sp. GNDU 1 produced high levels of extra-cellular inulinase (0.552 IU/ml) after 24 h at pH 7.5, temperature 46 degrees C in the presence of 1% inulin. The optimum temperature and pH for enzyme activity were 60 degrees C and 5.5 respectively. Yeast extract as a nitrogen source was found to be most suitable one for inulinase production whereas ammonium ion was inhibitory to the enzymatic production. All these conditions make Streptomyces sp. GNDU 1, a potential candidate for industrial enzymatic production of fructose from inulin.
