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.

CONTROL OF ASPERGILLUS NIGER IN HYACINTHS
Acta Horticulturae, 1997During the 2-5 years of cultivation of hyacinth bulbs there are many occasions for an infection by Aspergillus niger. The most important factors are cultivar, bulbsize, damage, temperature, relative humidity, multiplication method and disinfection. The time of grading (= damaging) has a big influence on the number and the type of infections.

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.

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 ...

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.

Some observations on the aspergillin of Aspergillus niger
Archives of Biochemistry and Biophysics, 1968Abstract The presence of a general inhibitor of enzymes has been established from several strains of Aspergillus niger, although the amount present showed wide variations. The inhibitor is identical with or closely related to the black pigment aspergillin, and is absent from all but black-colored spores.
