What is produced using 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).

Which fungi produce lipase?

Some important lipase-producing fungal genera include Aspergillus, Penicillium, Rhizopus, Candida, etc. Current fermentation process techniques such as batch, fed-batch, and continuous mode of lipase production in submerged and solid-state fermentations are discussed in details.

Which enzyme got from Aspergillus?

Aspergillus Enzymes for Industries

Enzyme Source Function
α-Amylase Aspergillus spp. Wheat starch hydrolysis
Amyloglucosidase Aspergillus niger Hydrolysis of starch dextrins to glucose
Cellulase Aspergillus niger Hydrolysis of cellulose
β-Glucanase Aspergillus spp. Hydrolysis of β-glucan

Which test is used to detect the ability of microorganisms to produce lipase?

Tributyrin agar
Tributyrin agar is a differential medium that tests the ability of an organism to produce an exo-enzyme, called lipase that hydrolyzes tributyrin oil.

Is Aspergillus 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 diseases does Aspergillus niger cause?

Aspergillus niger causes several diseases including black mold (or black rot) of onions and garlic, crown rot of peanuts, and vine canker of table grapes. In black rot of onions and garlic, A. niger develops between the outer (dead, flaky) skin and the first fleshy scales of the bulb which become water soaked.

What is fungal lipase?

Fungal lipases constitute an important group of biotechnologically important enzymes because of the versatility of its properties and ease of mass production. Fungal lipases are versatile in its enzymatic properties and substrate specificity, which make it very attractive for industrial applications.

How is lipase used in industry?

The physiologic role of lipases is to hydrolyze triglycerides into diglycerides, monoglycerides, fatty acids, and glycerol. The most significant industrial applications of lipases have been mainly found in the food, detergent, and pharmaceutical sectors.

Where is Aspergillus nidulans found?

nidulans is not common in foods, and has not been implicated in actual spoilage, but has been isolated from a wide variety of sources. The most common reports are from cereals and cereal products (wheat, flour and bread, barley, rice, maize, and sorghum), nuts (peanuts, hazelnuts), dried beans and spices.

How are Aspergillus infections caused?

Usually, aspergillosis is caused by inhaling Aspergillus spores. Most people inhale these spores every day without being affected. But if the immune system is weak, infection is more likely because aspergillosis is an opportunistic fungal infection (one that takes advantage of a weakened immune system).

How do you test lipase activity?

A lipase test is usually in the form of a blood test. During a blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial.

How do you test for lipase activity?

The presence of lypolitic activity is detected by the appearance of a transparent halo around the colonies. This assay is indicated for the detection of esterase activity. If you want to confirm the presence of a “true” lipase you have to use a long chain triglyceride.
