Purification and Characterization of Alkaline Xylanases from Bacillus polymyxa.
By applying different classical and fast protein liquid chromatographic techniques, three xylanases (beta-1,4-d-xylan xylanhydrolase) were purified to homogeneity from the extracellular enzymatic complex of Bacillus polymyxa. The three enzymes (X(34)C, X(34)E, and X(22)) were small proteins of 34, 34, and 22 kDa and basic pIs 9.3, >9.3, and 9.0, respectively. X(34)C and X(34)E are closely relat...
متن کاملProduction of 2,3-butylene glycol from citrus wastes. II. The Bacillus polymyxa fermentation.
The conditions required for production of levo 2,3-butylene glycol by Bacillus polymyxa from citrus molasses were studied. Starter cultures required acclimatization to the substrate prior to inoculation of the fermentation medium. Maximal production of butylene glycol with minimal residual sugar was obtained with a medium consisting of molasses, diluted to 20 degrees Brix, and 0.4% urea. Optima...
متن کاملProduction of Xylanases and Cellulases by Aspergillus Fumigatus Ms16 Using Crude Lignocellulosic Substrates
Xylanolytic and cellulolytic potential of a soil isolate, Aspergillus fumigatus (MS16) was studied by growing it on a variety of lignocellulosics, purified cellulose and xylan supplemented media. It was noted that carboxymethyl cellulose, salicin and xylan induce the production of endoglucanase, β-glucosidase and xylanase, respectively. The study revealed that Aspergillus fumigatus (MS16) co-se...
متن کاملComparison of growth and pectolytic enzyme production by Bacillus polymyxa.
Nagel, Charles W. (University of California, Davis) and Reese H. Vaughn. Comparison of growth and pectolytic enzyme production by Bacillus polymyxa. J. Bacteriol. 83:1-5. 1962.-Studies were made of pectolytic enzyme production by Bacillus polymyxa during growth. It was found that elaboration of enzyme occurred during logarithmic growth and ceased when the stationary phase was reached. The speci...
متن کاملEnhanced Endoglucanase Production by Bacillus aerius on Mixed Lignocellulosic Substrates
Selected carbon sources including soluble carboxymethyl cellulose (CMC), insoluble microcrystalline cellulose (MCC), and single (SS)/mixed lignocellulosic substrates (MS), were evaluated for endoglucanase production by B. aerius S5.2. The lignocellulosic substrates of oil palm empty fruit bunch (EFB), oil palm frond (OPF), rice husk (RH), and their mixture (MS) supported growth of the strain be...
