What is produced by Aspergillus niger?
What is produced by Aspergillus niger?
Aspergillus niger is a fungal microbe of great industrial importance. This mold is used extensively in the production of citric acid and in the production of several enzymes such as amylases, pectinases, and proteases (Godfrey and West, 1996).
What is Aspergillus niger fermentation?
Aspergillus niger fermentation has provided the chief source of industrial citric acid for over 50 years. The parent citric acid-producing strain of A. niger, ATCC 1015, has been described previously by a genome-scale metabolic model that encapsulates its response to ambient pH.
Is Aspergillus niger toxic?
Aspergillus niger can produce a variety of fungal metabolites, termed mycotoxins, depending upon growth conditions and the strain of the organisms. The mycotoxins range from moderately to highly toxic in terms of acute toxicity.
Why is Aspergillus niger important?
Aspergillus niger is a filamentous ascomycete fungus that is ubiquitous in the environment and has been implicated in opportunistic infections of humans. In addition to its role as an opportunistic human pathogen, A. niger is economically important as a fermentation organism used for the production of citric acid.
What is the role of Aspergillus niger?
Which is wild type of Aspergillus produces xylanase?
This person is not on ResearchGate, or hasn’t claimed this research yet. Xylanase production by wild-type Aspergillus niger ANL301, newly isolated from wood-waste, was monitored at 24 h intervals for a period 168 h in media containing different carbon sources.
What kind of substrate does Aspergillus niger use?
Xylanase production by Aspergillus niger via Solid State Fermentation was carried out using various substrates in an economically low operational cost in solid state cultivation offers advantages over liquid cultivation, especially for fungal cultures.
What are the carbon sources of Aspergillus niger ANL 301?
Xylanase production by wild-type Aspergillus niger ANL301, newly isolated from wood-waste, was monitored at 24 h intervals for a period 168 h in media containing different carbon sources. The carbon sources were oat-spelt xylan (Fluka) and three agro-wastes (sawdust, sugarcane pulp and wheat bran).
Which is more active in the production of xylanase?
Generally, A. niger is more active in xylanase production compared with T. viride when grown on 1.0 g barley bran with moisture levels of 1:3 (75%), at pH 5.5 and 35°C after 2.0 days incubation in absence of additive nitrogen source.
