Xylanase 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 کاملPartial Purification and Properties of Cellulase-Free Alkaline Xylanase Produced by Rhizopus stolonifer in Solid- State Fermentation
Rhizopus stolonifer was cultivated in wheat bran to produce a cellulase-free alkaline xylanase. The purified enzyme obtained after molecular exclusion chromatography in Sephacryl S-200 HR showed optimum temperature as 45o C and hydrolysis pHs optima as pH 6.0 and 9.0. Xylanase presented higher Vmax at pH 9.0 (0.87 μmol/mg protein) than at pH 6.0 and minor Km at pH 6.0 (7.42 mg/mL) than at pH 9.0.
متن کاملMultiple Parameter Optimization for Maximization of Pectinase Production by Rhizopus sp. C4 under Solid State Fermentation
A novel strain Rhizopus sp. C4 was isolated from compost for the production of pectinase. Cultivation of Rhizopus sp. C4 on orange peel substrate under various solid-state fermentation (SSF) conditions was evaluated for pectinase yield along with the enzyme activity profile as a potential, low-cost alternative to submerged-liquid fermentation. Response surface methodology (RSM) was employed to ...
متن کاملOptimization of Xylanase Production fromPenicillium citrinum in Solid-State Fermentation
Solid-state fermentation of sugarcane bagasse by Penicillium citrinum MTCC 2553 was optimized to maximize the yield of xylanase. Preliminary experiments carried out with various lignocellulosic materials revealed sugarcane bagasse to be the most suitable substrate for producing xylanase. Response surface methodology was used in the optimization. Xylanase activity was maximized in a 5-day batch ...
متن کاملXYLANASE from STREPTOMYCES HYGROSCOPICUS under Solid State Fermentation
The objectives of the present study were isolation, identification, and characterization of xylanase producing actinomycetes, optimization of medium composition and cultural conditions for xylanase production, production using cheaper sources and extraction of extra cellular xylanase from a potential strain. Streptomyces hygroscopicus was selected and optimized for xylanase production in solid ...
