CotA laccase, a novel aflatoxin oxidase from Bacillus licheniformis, transforms aflatoxin B1 to aflatoxin Q1 and epi-aflatoxin Q1

Food Chemistry, 2020
In the present study, the CotA protein from Bacillus licheniformis ANSB821 was cloned and expressed in Escherichia coli. Apart from the laccase activities, we found that the recombinant CotA could effectively oxidize aflatoxin B1 in the absence of redox mediators.

Aflatoxin and chromosomal studies [PDF]

Bulletin of Environmental Contamination and Toxicology, 1966
Aspergillus flavus is known to be a common fungal contaminant on groundnuts, groundnut cake, and meal, Four metabolites have been designated as comprising the toxins produced by the fungus. Collectively, the B1, B2, G1, and G2 toxic factors have come to be called aflatoxin; the B1 form being considered the most common naturally occurring form.

Aflatoxins and Disease

The American Journal of Tropical Medicine and Hygiene, 1981
These days it is widely believed by experts that most cancers are caused by environment factors. The epidemiology of most of these suspected factors is still equivocal. One such factor which has been widely studied is aflatoxin, a chemical produced by the fungus Aspergillus flavus.

Influences of climate on aflatoxin producing fungi and aflatoxin contamination

International Journal of Food Microbiology, 2007
Aflatoxins are potent mycotoxins that cause developmental and immune system suppression, cancer, and death. As a result of regulations intended to reduce human exposure, crop contamination with aflatoxins causes significant economic loss for producers, marketers, and processors of diverse susceptible crops.

Incidence of aflatoxins and aflatoxin producing fungi in animal feedstuffs

Mycopathologia, 1979
Fifty four samples including 5 of broken rice, 8 of corn grains, 8 of corn gluten feed, 13 of cottonseed cake and 4 each of rice polish, corn gluten, sesame oil cake, guar meal and wheat bran were screened for the presence of aflatoxins. Among all the samples, 14 were damaged and 40 apparently undamaged.

Ecology of aflatoxin producing fungi and biocontrol of aflatoxin contamination

Mycotoxin Research, 2006
Aflatoxins, highly toxic and carcinogenic compounds that frequently contaminate foods and feeds, are produced by several genera in the genusAspergillus. Aspergillus flavus, the most common species causing crop contamination, is a common inhabitant of the Sonoran desert of North America where it resides in complex communities composed of diverse ...

Biotransformation of Aflatoxin

Food Biotechnology, 1989
Abstract Food grade fungi were screened for their capacity to degrade aflatoxin B1 (AFB1) in order to develop a biological detoxification process for contaminated feeds. An agar technique based on defluorescence of AFB1 was used for this purpose.
