Extracellular xylanase production by the newly isolated Bacillus cereus BSA1 in presence of different nitrogen and phosphate sources and metal ions was optimized under submerged fermentation. The growth of bacteria and its enzyme production were maximum in the presence of beef extract. Maximum enzyme production was done in presence of Na2HPO4 and the most effective concentration was achieved in 0.10%. The most effective salt for xylanase production by the bacteria was NaCl. This article says about the smart and successful production of xylanase from a mesophilic soil bacterium, Bacillus cereus BSA1.
