Exocellular Inulinase of Bacillus subtilis Studies on inulinases produced by some bacteria. Methods for characterization of Streptomyces species.

Isolation and characlerization of bacterial strains with inulinase activity.

Oligosaccharides are compounds with great potential of use in food industry particularly interesting are fructooligosaccharids FOSbecause of their favorable functional properties such as low calorie and noncariogenic sweeteners, improvement of the intestinal microbial flora, relief of constipation, decrease of total cholesterol and lipid in the serum and promotion of animal growth Vandamme and Derycke, Therefore, microbial inulinases which can be induced by growing microorganisms, have a potential for industrial use in the production of fructose frminulin Edelman and Jefford, In the present review, various properties of inulin as a potent substrate for inulinase production are summarized.

The production broth medium was optimized for maximum inulinase production by addition of 0. The analysis of the deduced inulinase amino acid sequence revealed the presence of a putative gram-positive signal purificatioj and a cleavage site following purificatioon acid 39 was predicted with the program designed by Nielsen et al.

Besides, various promising applications and aspects of enzymatic hydrolysis for producing important industrial products also have been discussed. Results represented in Table 8 Indicated that the inulinase activity increased with increasing the substrate concentration until 1 mu and the activity was constant between 1- muinulin.

Inulin was the best carbon source for inulinase production, while starch, maltose and lactose were inadequate.

Production, Purification, Characterization and Applications of Fungal Inulinases | BenthamScience

Therefore, this study aimed to collate all information, particularly on fungal sources, characteristics, and applications of inulinases. Effect of pH value on the specific activity of purified inulinase from Streptomyces grisenus. However pure enzyme was stable in the presence of CaCl 2. 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 culture 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.

Purification of the extra cellular inulinase: Problems of Classification of Actinomycetes Antagonists. Production of inulin fructotransferase depolymerizing by Artrobacter sp. Purification and characteristics of two exoinulinases from Chrysosporium pannorum J.
