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 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 کاملProduction of amylases by Aspergillus tamarii in solid state fermentation at high initial glucose concentrations
The effect of glucose and other soluble sugars (xylose, fructose, maltose, cellobiose and lactose) in the production of amylases by Aspergillus tamarii was studied in solid state fermentation (SSF). Wheat bran solid state cultures were resistant to catabolite repression even at high concentration of glucose (10%). Results show the potential of solid state systems to overcome the adverse effects...
متن کاملWhy Solid-State Fermentation Seems to be Resistant to Catabolite Repression?
A critical review of the phenomenon of resistance to catabolite repression of enzyme synthesis by solid-state fermentation (SSF) has been made. The practical and theoretical importance of such phenomenon is commented, together with the current ideas to explain it. Namely, the possible existence of microscopic gradients within the mass of cell aggregates, or the changes in cell permeability to s...
متن کاملGluconic acid production by Aspergillus niger mutant ORS-4.410 in submerged and solid state surface fermentation.
Aspergillus niger ORS-4.410, a mutant of Aspergillus niger ORS-4 was produced by repeated irradiation with UV rays. Treatments with chemical mutagnes also resulted into mutant strains. The mutants differed from the parent strain morphologically and in gluconic acid production. The relationship between UV treatment dosage, conidial survival and frequency of mutation showed the maximum frequency ...
