Solid State Fermentation for Production of Chitosan by Aspergillus Niger
The effect of Solid State Fermentation (SSF) on Chitosan production by A. niger was investigated. A. niger BBRC 20004 from Biochemical and Bioenvironmental Research Centre of Sharif University of Technology (Tehran, Iran), was grown on corn residue. Chitosan was extracted from the fungal mycelia using hot alkaline and acid treatment. A. niger was incubated for 12 days on corn residue with moist...
متن کاملProduction of Bacterial - Xylanolytic Enzyme using Agricultural Waste by Solid State Fermentation
Xylanases (E.C.3.2.1.8) are key enzymes, which play an important role in the breakdown of xylan. Wheat bran and corn cob are a rich source of xylan (28%) and xylose (23%). Therefore these are attractive substrates for production of xylanase & ßxylosidase enzyme. Xylan, a major component of hemicelluloses, is a heterogeneous polysaccharides consisting of ß-1, 4 linked to D-xylosyl residues on th...
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 کاملCellulolytic Enzymes Production via Solid-State Fermentation: Effect of Pretreatment Methods on Physicochemical Characteristics of Substrate
We investigated the effect of pretreatment on the physicochemical characteristics-crystallinity, bed porosity, and volumetric specific surface of soybean hulls and production of cellulolytic enzymes in solid-state fermentation of Trichoderma reesei and Aspergillus oryzae cultures. Mild acid and alkali and steam pretreatments significantly increased crystallinity and bed porosity without signifi...
متن کاملA Comparative Study of New Aspergillus Strains for Proteolytic Enzymes Production by Solid State Fermentation
A comparative study of the proteolytic enzymes production using twelve Aspergillus strains previously unused for this purpose was performed by solid state fermentation. A semiquantitative and quantitative evaluation of proteolytic activity were carried out using crude enzymatic extracts obtained from the fermentation cultures, finding seven strains with high and intermediate level of protease a...
