Production of amylases by Aspergillus tamarii in solid state fermentation at high initial glucose concentrations
نویسندگان
چکیده
The effect of glucose and other soluble sugars (xylose, fructose, maltose, cellobiose and lactose) in the production of amylases by Aspergillus tamarii was studied in solid state fermentation (SSF). Wheat bran solid state cultures were resistant to catabolite repression even at high concentration of glucose (10%). Results show the potential of solid state systems to overcome the adverse effects of high sugar concentrations in the media. The ability to prevent catabolite repression appear to be related with the content moisture of solid state systems: less content moisture of cultures means less catabolite repression caused by glucose.

Nine Aspergillus and three of Trichoderma strains were grown on wheat bran (WB) medium under solid state fermentation (SSF) for amylase production. Aspergillus oryzae LS1 produced the highest level of the enzyme. The thermal stability profile of its crude enzyme revealed the half-life time of more than 2 h at 50 and 60ºC. The enzyme production was affected by strain type, incubation periods, le...
