Effect of purkfication or partly soluble dietary fibres supplementation on absorption and balance of calcium, magnesium, iron and zinc in healthy young men. These authors concluded that inulin induces inulinase production, where as cultivation using starch, maltose and lactose as carbon source s restrains the production of this enzyme by optimizing inulinade conditions for maximum inulinase production, purification of streptomyces grisenius crude inulinase in cell free extracts was the aim of further research in order to increase its specific enzyme activity.

Effect of different substrate concentration on the purified inulinase produced by Streptomyces grisenus.
