High-Potency Amyloglucosidase-Producing Mold of the Aspergillus niger Group

High-potency Amyloglucosidase-producing Mold of the Aspergillus Niger Group.

The action of an amyloglucosidase of Aspergillus niger on starch and malto-oligosaccharides.

Earlier reports from a number of laboratories (l-3) have shown that Aspergillus niger produces several enzymes with ability to hydrolyze the a-~-(1 ---f 4) glucosidic linkages in starch and maltooligosaccharides. Important members of this group include a-amylase, amyloglucosidase and maltase. Within recent years there has been considerable interest in the amyloglucosidase group of enzymes since...

Immobilization of polymethylgalacturonase producing Aspergillus niger on Luffa sponge material.

The vegetable sponge of Luffa cylindrica was studied as a matrix for the immobilization of Aspergillus niger 26, producer of polymethylgalacturonase (PMG). Entrapped spores could grow and multiply within the lattice of the sponge. The influence of loofa sponge inoculum content, initial spore inoculum content, and duration of the growth cycle on the enzyme activity and mycelium growth was studie...

Heavy Metals Accumulation Potency of Aspergillus Niger and Aspergillus Flavus Indigenous to Paper Mill Effluent

Heavy metals are categorized based on their high density, atomic weight, atomic number and molecular weight. Lewis acids property of metal ions results in covalent complex formation with different ligands in humans and other living forms which make metals nondegradable and cause toxicity (Duffus, 2002). Pulp and paper mill are categorized as one of the 12 most polluting industries in India whic...

Comparative genomics of citric-acid-producing Aspergillus niger ATCC 1015 versus enzyme-producing CBS 513.88.

The filamentous fungus Aspergillus niger exhibits great diversity in its phenotype. It is found globally, both as marine and terrestrial strains, produces both organic acids and hydrolytic enzymes in high amounts, and some isolates exhibit pathogenicity. Although the genome of an industrial enzyme-producing A. niger strain (CBS 513.88) has already been sequenced, the versatility and diversity o...
