چکیده

Xylanase execute a large variety of function and have many important in biotechnological application. Its application in paper industry, pulp industry, increases the self life of bread, food ndustry. The production of xylanase was investigated in submerged culture of Aspergillus niger. This study was carried out in isolation and screening of xylanase enzyme from the Aspergillus niger fungus. This fungus is isolated from agricultural soil, decayed bread and waste material. The maximum concentration of xylanase enzyme found at 25 0 c and also maximum production occurred when the pH was controlled at 6.0 during the fermentation. It have the maximum concentration. It has lot of industrial application.

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...

Xylanase production by a newly isolated Aspergillus niger SS7 in submerged culture.

Xylanase production by a newly isolated Aspergillus niger SS7 was studied in submerged culture. The optimum initial pH for xylanase production was found to be 7.0. Different agricultural and industrial wastes were evaluated for their ability to induce xylanase production by this isolate. The best xylanase production (293.82 IU/ml) was recorded at 3% (w/v) corn cob hulls after 120 h of incubatio...

Bioprocess and biotecnology: effect of xylanase from Aspergillus niger and Aspergillus flavus on pulp biobleaching and enzyme production using agroindustrial residues as substract

This study compares two xylanases produced by filamentous fungi such as A. niger and A. flavus using agroindustrial residues as substract and evaluated the effect of these enzymes on cellulose pulp biobleaching process. Wheat bran was the best carbon source for xylanase production by A. niger and A. flavus. The production of xylanase was 18 and 21% higher on wheat bran when we compare the xylan...

Improvement of Xylanase Production by a Parasexual Cross between Aspergillus niger strains

A diploid strain (D4) isolated via parasexual recombination between two Aspergillus niger xylanase overproducing mutants was characterised in terms of enzyme production and catabolite repression by glucose. This strain increased xylanase production (607 nkat/ml), which was nearly 100% higher than titers achieved by the wild type strain (305 nkat/ml) and 28% higher than the best mutant used to i...
