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...
متن کاملBiocatalytic 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 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 کاملFungal Protease Production by Aspergillus niger and Aspergillus flavus Using Rice Bran as the Substrate
Micro-organisms are capable of producing extracellular proteases that degrade proteins into amino acids to make their assimilation possible (Zouari et al., 1999). A large number of micro-organisms including bacteria, yeast and fungi produce different groups of enzymes. Selection of a particular strain, however, remains a tedious task, especially when commercially competent enzyme yields are to ...
متن کاملProduction and Evaluation of Chitosan from Aspergillus Niger MTCC Strains
Three different Aspergillus Niger MTCC strains (872, 1785 and 2208) were used for the production of chitosan. Multivariate growth mediums in varying incubation periods were analyzed for the production. The produced chitosan was characterized by its physical appearance, moisture content (by means of gravimetric method), percentage of ash and solubility (through the Association of Official Agricu...
