Abstract

Aspergillus flavus, in solid culture, was exposed to individual selected, commercially obtained volatile compounds that were similar to volatile cotton leaf-derived components. The radial growth pattern of A. flavus and the production of aflatoxin were determined on these volatile exposed cultures. The most bioactive compounds C6-C9 alkenals, completely inhibited the growth of the fungus. Unexpected results demonstrated that 3-methyl-1-butanol and 3-methyl-2-butanol inhibited A. flavus growth by 20% but increased production of aflatoxin B1 by 1.5 to 2-fold. Other relationships of growth and aflatoxin production resulting from exposure to the bioactive volatiles are discussed.

Aspergillosis (ASM)

Aspergillosis is the name given to a wide variety of diseases caused by infection by fungi of the genus Aspergillus. Aspergillosis occurs in chronic or acute forms which are clinically very distinct. Most cases of acute aspergillosis occur in patients with severely compromised immune systems. Chronic colonization or infection can cause complications in people with underlying respiratory illnesses. Discover the latest research on aspergillosis here.
