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).

Do fungi produce cellulase?

Most industrial cellulases are produced by fungi in submerged fermentation. Trichoderma reesei is the most important fungal species used for cellulase production although it produces low levels of β-glucosidase [5].

How is cellulase produced?

Cellulase is any of several enzymes produced chiefly by fungi, bacteria, and protozoans that catalyze cellulolysis, the decomposition of cellulose and of some related polysaccharides. Endogenous cellulases are produced by a few types of metazoan animals, such as some termites, snails, and earthworms.

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.

What does Aspergillus niger look like?

Cultural Characteristics of Aspergillus niger Generally, they have a cottony appearance; initially white to yellow and then turning black. Made up of felt-like conidiophores. The reverse is white to yellow. In microscopy, the conidial heads are radiate with conidiogenous cells biseriate.

Is Aspergillus black?

Aspergillus niger is a fungus and one of the most common species of the genus Aspergillus. It causes a disease called “black mold” on certain fruits and vegetables such as grapes, apricots, onions, and peanuts, and is a common contaminant of food….Genome.

NCBI genome ID 429
Genome size 34 Mb
Number of chromosomes 8

Is fungus and fungi the same?

Fungus, plural fungi, any of about 144,000 known species of organisms of the kingdom Fungi, which includes the yeasts, rusts, smuts, mildews, molds, and mushrooms. There are also many funguslike organisms, including slime molds and oomycetes (water molds), that do not belong to kingdom Fungi but are often called fungi.

Is Aspergillus the same as black mold?

The fungus Aspergillus niger is a type of mould, which can sometimes be attributed to the cause of some cases of pneumonia. It is also the causative agent of ‘black mould’ on the outsides of certain foods, such as apricots, onions, grapes, etc – therefore making Aspergillus niger a food ‘spoilage’ organism.

What kills Aspergillus fungus?

In both disseminated and limited cutaneous aspergillosis, high-dose intravenous amphotericin B, in traditional or liposomal form has been the traditional antifungal used to eradicate the underlying organism.

How long does it take to produce cellulase in Aspergillus niger?

This person is not on ResearchGate, or hasn’t claimed this research yet. Aspergillus niger was used for cellulase production in submerged (SmF) and solid state fermentation (SSF). The maximum production of cellulase was obtained after 72 h of incubation in SSF and 96 h in Smf.

What kind of fermentation is Aspergillus niger used for?

Aspergillus niger was used for cellulase production in submerged (SmF) and solid state fermentation (SSF). The maximum production of cellulase was obtained after 72 h of incubation in SSF and 96 h in Smf. The CMCase and FPase activities recorded in SSF were 8.89 and 3.56 U per g of dry mycelial bran (DBM), respectively.

What is the pH level of Aspergillus cellulase?

Among the various isolates obtained from different sampling sites, three different fungi were selected depending upon the clear zone diameter produced in Carboxymethyl Cellulose (CMC) agar. CMC hydrolysis by all three fungal strains exhibited their activities at pH 5.5-7.5, whereas maximum activity occurred at pH 5.5. Enzymes were also pH stable.

Where can I find cellulase in the soil?

Potential cellulase-producing fungi were isolated from different soil samples, particularly near agro-wastes dumping sites. Among the various isolates obtained from different sampling sites, three different fungi were selected depending upon the clear zone diameter produced in Carboxymethyl Cellulose (CMC) agar.
