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.

Biotransformation of (-)-Maalioxide by Aspergillus niger and Aspergillus cellulosae
HETEROCYCLES, 2004A sesquiterpene cyclic ether, (-)-maalioxide (1) from the liverwort Plagiochila sciophila was biotransformed by Aspergillus niger and A. cellulosae to afford the structurally interesting compounds The stereostructures of the metabolites were established by a combination of high resolution NMR spectrum, X-Ray crystallographic analysis and the chemical ...

Differentiation of the Polygalacturonases of Aspergillus niger
Nature, 1952IT has been long known that there is no close relationship between the physically and chemically measured action of polygalacturonase1. Jansen and MacDonnel2, Matus3, McColloch and Kertesz4, Reid5, Schubert6 and others have, from very different observations, suggested that the polygalacturonase preparations extracted from micro-organisms and plants ...

THE SUCCINOXIDASE SYSTEM INASPERGILLUS NIGER [PDF]
The succinoxidase system of Aspergillus niger differs from that of avian and mammalian tissues in its greater lability during preparation and storage but is similar in its sensitivity to malonate, cyanide, azide, and B.A.L., its association with cell particles, and its single pH optimum at pH 7.3.

Biotransformation of Turmerones by Aspergillus niger
Journal of Natural Products, 2010Biotransformation studies conducted on (+)-(S)-ar-turmerone (1) and (+)-(S)-dihydro-ar-turmerone (2) by the fungus Aspergillus niger have revealed that 1 was metabolized to give four oxidized metabolites, (+)-(7S)-hydroxydehydro-ar-todomatuic acid (3), (+)-(7S,10E)-12-hydroxydehydro-ar-todomatuic acid (4), (+)-(7S,10E)-7,12-dihydroxydehydro-ar ...

Cellulase of Aspergillus niger
1988Publisher Summary Cellulases play an important role in maintaining the carbon balance in nature. In most cellulolytic microorganisms, several cellulase components secreted into the culture filtrate together constitute a “cellulase system,” and insoluble cellulosic materials are converted to soluble sugar by their synergistic action.

OTOMYCOSE ASPERGILLAIRE À ASPERGILLUS NIGER
Maroc médical, 2013L’otomycose aspergillaire à Aspergillus Niger est une pathologie rare au regard du faible nombre de cas publiés dans la littérature mondiale. Elle se caractérise par la formation d’un bouchon mycélien au niveau du conduit auditif externe. Dans ce travail, nous rapportons deux observations d’otomycose aspergillaire à Aspergillus Niger.
