Biological degradation of aflatoxin M₁ by Bacillus pumilus E-1-1-1.

ABSTRACT: Aflatoxin M₁ (AFM₁ ) is a potent mycotoxin which causes serious health concerns in developing countries, where it is mainly found in milk, meat, and other foods. Biological detoxification is a promising method for eliminating AFM₁ . The aim of this work was to search for AFM₁ -degrading bacterial strains from animal waste, soil, and activated sludge. High-performance liquid chromatography and Fourier-transform infrared spectroscopy were used to analyze the AFM₁ degradation products. A strain designated E-1-1-1 was obtained from African elephants feces, with the degradation ratio of AFM₁ reaching 89.55% in 12 hr. Based on morphology, physiological and biochemical tests, and 16S rRNA gene sequence analysis, strain E-1-1-1 was
