Aspergillus niger is one of the most important microorganisms used in biotechnology. It has been in use already for many decades to produce extracellular (food) enzymes and citric acid. In fact, citric acid and many A. niger enzymes are considered GRAS by the United States Food and Drug Admin...
Safety of the fungal workhorses of industrial biotechnology: update on the mycotoxin and secondary metabolite potential ofAspergillus niger,Aspergillus oryzae, andTrichoderma reesei Abstract This review presents an update on the current knowledge of the secondary metabolite potential of the major fungal spe...
The colour of both could be measured, with a photronic cell. The determination of zinc proved also to be possible with the aid of the Aspergillus, the weight of the mycelium being proportional to the quantity of this element in the culture solution. However great care has to be taken to ...
Cover, Insert, and Table of Contents Photography: Estelle Levetin, PhD & Richard Portman, Biological Science, University of Tulsa. Aspergillus niger is a successful cosmopolitan saprophyte of common occurrence, and perhaps the most abundant species of Aspergillus.1,2 It is isolated from house dust...
Several mutants were isolated from the parent strain of Aspergillus niger CF: the first mutant strain CF-11 was obtained by UV irradiation, and the second mutant strain CF-21 and CF-22 were from NTG (N-methyl-N'-nitroso-N-nitroso-guanidine) treatment on the CF-11. These mutants were cha...
This growth causes esthetic problems and deterioration of its wall coatings. Spores from the fungi also cause health problems to humans. The fungus species studied in this research is Aspergillus niger. The material is made of wood and its finishing is thick wallpaper, thin wallpaper, acrylic ...
Employing Aspergillus niger strain 1617, we have made a kinetic analysis of the region of protease formation in the hypha.When the fungal hyphae, grown by shaking in the ordinary synthetic medium containing sulfate (+S medium), were tran... T Yanagita,Y Nomachi - 《J.gen.appl.microbiol》...
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. ...
