Abstract

Dextrans is a group of POLYSACCHARIDES (C6H10O5)n with glucose subunits. By consideration of its nonionic criterion, stability and other physico-chemical properties, dextran has a wide-range application in food, pharmaceutical and biochemical industries. In this study, effects of the most important factors affecting on the DEXTRAN PRODUCTION were studied by LEUCONOSTOC MESENTROIDES UTMC118. The results obtained showed that optimum conditions were: pH 9, 32oC, 50g/l sucrose, 20g/l yeast extracts 10% (v/v) inoculum size and there is no need to agitation.In order to find cheap and local media ingredients, DEXTRAN PRODUCTION by various concentration of molasses and baker-yeast were studied.Concentrations of 40g/l and 20g/l molasses and yeast extract found as the best industrial fermentation medium ingredients. Application of optimized condition increased the dextran concentration 3.5 times than that of control. Maximum dextran concentration was 80g/l. These results can reduce the cost of production by using the cheap raw materials.
