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...
متن کاملMicrobial 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...
متن کاملDetoxification 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...
متن کاملAflatoxin 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...
متن کاملAflatoxin detoxification by manganese peroxidase purified from Pleurotus ostreatus
Manganese peroxidase (MnP) was produced from white rot edible mushroom Pleurotus ostreatus on the culture filtrate. The enzyme was purified to homogeneity using (NH4)2SO4 precipitation, DEAE-Sepharose and Sephadex G-100 column chromatography. The final enzyme activity achieved 81 U mL(-1), specific activity 78 U mg(-1) with purification fold of 130 and recovery 1.2% of the crude enzyme. SDS-PAG...
