Properties of Aspergillus niger Catalase
The Journal of Biochemistry, 1982Catalase from Aspergillus niger was purified to homogeneity as judged from the results of ultracentrifugation and polyacrylamide gel electrophoresis. The enzyme had a molecular weight of 385,000 as estimated from sedimentation measurements. Carbohydrate analyses showed that the catalase was a glycoprotein containing about 8.3% neutral sugar and 1.9 ...

Phosphoglucomutase activity in aspergillus niger
Archiv f�r Mikrobiologie, 19631. Some of the properties of the phosphoglucomutase of Aspergillus niger have been studied in crude extracts of the mycelium. The results obtained have been compared with the data reported by previous workers for crude and for purified enzyme preparations from animal and plant sources and from yeast. 2.

Aspergillus Niger Infection of Exenterated Orbit
Ophthalmic Plastic and Reconstructive Surgery, 2001To present two immunocompetent patients with Aspergillus niger infection of the exenterated orbit.Case reports.The patients were treated with oral itraconazole and socket irrigation with amphotericin B. The sockets cleared completely; no growth was observed on reculturing.A niger infection of an exenterated socket can be effectively treated with oral ...

Aspergillus niger pectin lyases are encoded by a multigene family. The complete nucleotide sequence of the pectin lyase PLA-encoding gene pelA has been determined. Comparison of the deduced amino acid sequence with the deduced amino acid sequence of the other characterized pectin lyase, PLD, shows that the proteins share 69% amino acid identity.

Folia Microbiologica, 1994
132 microorganisms, isolates from soil and decayed fruits, were tested for phytase production. All isolates intensively producing active extracellular phytase were of fungal origin. The most active fungal isolates with phytase activity were identified as Aspergillus niger. At the end of the growth phase, the extracellular phytase activity produced by A.

Zinc Requirements of Aspergillus niger
Nature, 1951ZINC is indispensable for the growth of all the higher plants, fungi, Actinomycetes and bacteria which have been examined, yet little is known of the role of zinc in metabolism1,2. Evidence has been presented recently, however, that phosphatase of Penicillium chrysogenum, is a zinc-containing enzyme3.

Rassenumwandlung bei Aspergillus niger
Archiv f�r Mikrobiologie, 1935Es wurde versucht, zwei physiologisch durch die Oxalsaurebildung und die dadurch beeinfluste Richtung der Autolyse verschiedene Rassen von Aspergillus niger ineinander uberzufuhren. Dies gelang durch Einwirkung von Trocknen bzw. Erhitzen der Sporen und durch Passage uber Tannin- und Oxalsaurelosung.

THE HEXOSEMONOPHOSPHATE PATHWAY IN ASPERGILLUS NIGER
Canadian Journal of Microbiology, 1958Enzymes of the hexosemonophosphate pathway were demonstrated in extracts obtained from Aspergillus niger grown in two types of media: a fermentation medium (molasses) and a rich growth medium (MYG). Preparations from cells grown in either medium contained a TPN-specific glucose-6-phosphate (G-6-P) dehydrogenase and a TPN-linked 6-phosphogluconate (6-P ...

Degradation of Salicylate by Aspergillus niger
Nature, 1967SALICYLATE continues to be a leading cause of accidental poisoning in the United States; in 1964 there were more than 16,000 cases of accidental aspirin ingestion among all age groups, accounting for 25.8 per cent of all accidental poisonings reported1.
