Biocatalytic activity of Aspergillus niger xylanase in paper pulp biobleaching
Xylanase is a hemicellulase enzyme that catalyses the hydrolysis of xylan to xylose which is widely used in processing of feed, pulp and paper. It is produced by many microorganisms especially filamentous fungi like Trichoderma and Aspergillus. A potential xylanolytic fungal isolate Aspergillus niger was isolated from forest soils of Tirumala, AP, India, and its crude enzyme was checked for its...
متن کاملBiobleaching of Bagasse Pulp with Xylanase Enzymes and Hydrogen Peroxide
The effect of the operating conditions (temperature, time, pH, enzyme level and pulp consistency) used in the enzymatic step of a XP (Cartazyme-hydrogen peroxide) sequence for bleaching Kraft pulp from bagasse on various properties of the resulting pulp and paper sheet products was studied. The quality of bagasse used, was examined by its yield, brightness,viscosity and the Kappa number. Finall...
متن کاملXylanase Production from Aspergillus niger
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. Th...
متن کاملBioprocess 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...
متن کاملBiobleaching of Wheat Straw Pulp using Laccase and Xylanase
Wheat straw pulp can be considered to be one of most important raw materials for specialty and functional paper products. Bleaching sequences involving laccase and xylanase were applied to bleach wheat straw pulp. The bleached pulp properties after a sequence of xylanase (X), laccase (L), and extraction (E), i.e. XLE, were compared with those of LE and LEX sequences. It was found that the XLE b...
