Production of Xylanase on Natural Substrates by Bacillus subtilis
نویسندگان
چکیده
Bacillus subtilis, locally isolated, produced significant level of xylanase activity in the presence of different carbon sources. However, B. subtilis performed well when grown on pretreated natural substrates such as rice straw, wheat straw, bagasse, wheat bran and kraft pulp at 2% concentration. The organism produced higher level of xylanasse activity when bagasse was used as a carbon source followed by rice straw, wheat straw, wheat bran and kraft pulp. Xylanase activity was enhanced when different supplements were added in the bagasse medium. The maximal induction was observed when medium supplemented with 0.2% sucrose.

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 کاملEnhanced Production of Cellulase-free Xylanase by Alkalophilic Bacillus Subtilis Ash and Its Application in Biobleaching of Kraft Pulp
This paper reports high level production of a cellulase-free xylanase using wheat bran, a cost-effective substrate, under submerged fermentation by alkalophilic Bacillus subtilis ASH. Production of xylanase was observed even at alkaline pH up to 11.0 and temperature 60 °C, although the highest enzyme titer was recorded at neutral pH and 37 °C. The enzyme production under optimized fermentation ...
متن کاملSecretory Expression and Characterization of Two Hemicellulases, Xylanase, and β-Xylosidase, Isolated from Bacillus Subtilis M015
Microbial hydrolysis of lignocellulosic biomass is becoming increasingly important for the production of renewable biofuels to address global energy concerns. Hemicellulose is the second most abundant lignocellulosic biopolymer consisting of mostly xylan and other polysaccharides. A variety of enzymes is involved in complete hydrolysis of xylan into its constituent sugars for subsequent biofuel...
متن کاملUV mutagenesis for the overproduction of xylanase from Bacillus mojavensis PTCC 1723 and optimization of the production condition
Objective(s):[p1] This study highlights xylanase overproduction from Bacillus mojavensis via UV mutagenesis and optimization of the production process. Materials and Methods:Bacillus mojavenis PTCC 1723 underwent UV radiation. Mutants’ primary screening was based on the enhanced Hollow Zone Diameter/ Colony Diameter Ration (H/C ratios) of the colonies in comparison with the wild strain on Xyla...
متن کاملA novel halotolerant xylanase from marine isolate Bacillus subtilis cho40: gene cloning and sequencing.
Although several xylanases have been studied, only few xylanases from marine micro-organisms have been reported. We report here a novel halotolerant xylanase from marine bacterium Bacillus subtilis cho40 isolated from Chorao island of mandovi estuary Goa, India. Extracellular xylanase was produced by using agricultural residue such as wheat bran as carbon source under solid-state fermentation (...
