Microbial detoxification of aflatoxin.

Yeasts, molds, bacteria, actinomycetes, algae, and fungal spores were screened for their ability to degrade aflatoxin. Some molds and mold spores partially transformed aflatoxin B(1) to new fluorescing compounds. Only one of the bacteria, Flavobacterium (aurantiacum?) NRRL B-184, removed aflatoxin from solution. Both growing and resting cells of B-184 took up toxin irreversibly. Toxin-contamina...

Aflatoxin Detoxification : Hydroxydihydro - Aflatoxin B 1

A large number of microorganisms were screened in shaken-flask culture for their ability to detoxify the fungal toxin, aflatoxin B, (A. Ciegler et al., Appl. Microbiol. 14:934, 1966). We noted formation of a new fluorescing compound with concomitant disappearance of aflatoxin B, when toxin was added to acid-producing mold cultures. Steaming the culture before addition of toxin did not prevent f...

Detoxification of Aflatoxin - Contaminated Agricultural Commodities

Aflatoxin-contaminated commodities can be detoxified by a variety of methods based to some extent on economics and the physical and chemical characteristics of the substance being treated. Electronic and hand sorting of peanuts with ammoniation of contaminated oilseed meals and corn currently appears to offer the most promise. Microbiological decontamination appears to be the least feasible met...

Aflatoxin Detoxification in Rice using Citric Acid

BACKGROUND Aflatoxins cause health hazards to human and animals and has also economical problems. Therefore, the detoxification effect of citric acid was investigated in rice as the main food of Iranian people. METHODS Initially 275 samples of rice were examined for aflatoxins by HPLC. The aflatoxins contaminated samples were later treated by aqueous citric acid and detoxification of aflatoxi...

Decomposition and detoxification of aflatoxin B1 by lactic acid.

BACKGROUND A degradation study of aflatoxin B1 (AFB1) was carried out using a combination of physical and chemical methods. AFB1 was heated at 80 °C in the presence of acetic, citric and lactic acids for various time periods. The cytotoxicity of the degraded AFB1 and its products were determined by MTT assay. RESULTS The results showed that among the three organic acids lactic acid was most e...
