Purification and properties of a cellulase from Aspergillus niger.
A cellulolytic enzyme was isolated from a commercial cellulase preparation form Aspergillus niger. A yield of about 50mg of enzyme was obtained per 100g of commerial cellulase. The isolated enzyme was homogeneous in the ultracentrifuge at pH 4.0 and 8.0, and in sodium dodecyl sulphate/polyacrylamide-gel electrophoresis but showed one major and two minor bands in disc gel electrophoresis. No car...
متن کاملPurification and Properties of the Glucose Oxidase from Aspergillus Niger.
Glucose oxidase (/3-n-glucose : 02 oxidoreductase, EC 1.1.3.4) has been highly purified from the extracts of three fungi, Penicillium not&urn (1, 2), Penicillium amagasakiense (3, 4), and Aspergillus niger (5, 6). It has also been identified and sometimes partially purified from a number of other sources. Some of these sources are reviewed by Schepartz and Subers (7). Recently Pazur and Kleppe ...
متن کاملCatalytic Properties of Lipase Extracts from Aspergillus niger
Screening of lipolytic strains using Rhodamine-B/olive oil plate technique allowed the selection of Aspergillus niger MYA 135. Lipase production in submerged culture containing 2 % olive oil was enhanced by more than 50 % compared to basal cultural conditions. Optimal catalytic conditions for olive oil-induced lipase were pH=6.5 and 30–35 °C. These values were shifted to the acid region (4.0–6....
متن کاملPurification and properties of a beta-mannosidase from Aspergillus niger.
A beta-mannosidase (beta-D-mannoside mannohydrolase, EC 3.2.1.25) was purified to apparent homogeneity from the culture filtrate of the fungus, Aspergillus niger. The enzyme had an estimated molecular weight of about 120,000 and was a glycoprotein. Radioactive enzyme was prepared by growing the fungus in [14C]fructose, and this enzyme was used for the preparation of 14C-glycopeptides. The glyco...
متن کاملElectrophoretic properties of spores of Aspergillus niger.
This report concerns an investigation of an important aspect of fungal growth, the nature of the spore surface. The spore is the propagative body of the fungus so a knowledge of its germination process is of primary importance. The surface of the spore necessarily plays an integral part in this process since it is the first point of contact between the spore and such factors as water, food, and...
