Effect of Medium Composition on Xylanase Production by Bacillus subtilis using Various Agricultural Wastes
In the present study a strain of Bacillus subtilis-BS05 was grown in submerged fermentation of agricultural wastes for xylanolytic activity. Various agricultural wastes such as sugarcane bagasse, wheat straw, rice husk, soybean meal, corn cobs and wheat bran were evaluated for xylanolytic acitivity using different media (M-I, M-II, M-III & M-IV). Among all these tested substrates maximum xylano...
متن کاملBioprocess and biotecnology: effect of xylanase from Aspergillus niger and Aspergillus flavus on pulp biobleaching and enzyme production using agroindustrial residues as substract
This study compares two xylanases produced by filamentous fungi such as A. niger and A. flavus using agroindustrial residues as substract and evaluated the effect of these enzymes on cellulose pulp biobleaching process. Wheat bran was the best carbon source for xylanase production by A. niger and A. flavus. The production of xylanase was 18 and 21% higher on wheat bran when we compare the xylan...
متن کاملXylanase Production under Solid State Fermentation by Aspergillus niger
Central composite orthogonal design was applied to quantify relations of xylanase production, loss of dry matter and change of pH with four critical variables during solid state fermentation of a mixture of wheat bran and wheat straw on which Aspergillus niger CCUG 33991 was cultivated. The studied variables included the percentage of wheat straw, temperature, moisture content, and fermentati...
متن کاملProduction of Cellulases and Xylanase by Thermophilic and Alkaliphilic Bacterial Strains Isolated from Agricultural Wastes
Seven agricultural wastes named wheat bran (WB), rice straw (RS), wheat straw (WS), corn cob (CC), sugarcane bagasse (SCB), potato peal (PP) and banana peal (BP) were used for isolation of bacterial strains and as substrate for cellulases (CMCase, FPase and avicelase) and xylanase production. Five of the isolated strains were thermophilic and alkaliphilic. These bacterial isolates were tested t...
متن کاملStudies on an alkali-thermostable xylanase from Aspergillus fumigatus MA28
An alkalitolerant fungus, Aspergillus fumigatus strain MA28 produced significant amounts of cellulase-free xylanase when grown on a variety of agro-wastes. Wheat bran as the sole carbon source supported higher xylanase production (8,450 U/L) than xylan (7,500 U/L). Soybean meal was observed to be the best nitrogen source for xylanase production (9,000 U/L). Optimum medium pH for xylanase produc...
