What is the significance of Aspergillus flavus in grain products?
What is the significance of Aspergillus flavus in grain products?
Aspergillus flavus is a fungus pathogenic to maize causing an important ear rot disease when plants are exposed to drought and heat stress. The alpha-amylase of A. flavus promoted aflatoxin production in the endosperm of infected maize kernels.
Is Aspergillus flavus a bacteria or fungi?
Aspergillus flavus is a fungal pathogen that causes Aspergillus ear and Kernel rot. The fungus is mostly found in soil as saprophytes, but it has a broad host range as an opportunistic pathogen.
How does Aspergillus flavus affect humans?
Growth of the fungus on a food source often leads to contamination with aflatoxin, a toxic and carcinogenic compound. Aspergillus flavus is also the second leading cause of aspergillosis in humans. Patients infected with A. flavus often have reduced or compromised immune systems.
Is Aspergillus flavus a mycotoxin?
A mycotoxin is a toxic secondary metabolite produced by fungi, one species being Aspergillus flavus. Not all species of Aspergillus produce mycotoxins but A. flavus is among those who do.
What is the importance of Aspergillus?
Aspergillus causes rot of figs and dates, decay of tobacco and cigars. It spoils nuts, bread and other food-stuffs. In humid weather it grows even on leather and cloth fabrics. To cut short this cosmopolitan genus is one of the most frequent contaminants of food.
What is Aspergillus used for?
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 fungus?
Aspergillosis is an infection caused by Aspergillus, a common mold (a type of fungus) that lives indoors and outdoors. Most people breathe in Aspergillus spores every day without getting sick.

What is the pathophysiology of aspergillosis?
The haploid filamentous fungus Aspergillus flavus causes approximately 30% of the cases of aspergillosis, a serious human disease. It also produces the highly carcinogenic mycotoxin aflatoxin. Infestations of grains by this fungus results in large agricultural and economic losses.
