Abstract
Deoxynivalenol (DON) is very harmful to food and feed. Biological detoxification is an effective method to reduce the harmful effect and ensure safety of food and feed. In order to screen the strains that can detoxify DON 10 samples were selected from the mouldy alfalfa silage; and the LB NA and MRS media with DON were used for primary screening and re-screening. The detoxification rate of DON was measured and calculated by ELISA method. The strains with high detoxification rate of DON were identified by morphology and 16S rDNA sequence analysis. The selected strains were combined and used to ferment the bran and the detoxification efficiency of DON in the bran was then determined. Sixteen strains with the ability of detoxification were screened and the results showed that the highest detoxification rate was 66.75. Three strains with high detoxification rate were isolated and identified as Bacillus subtilis Pediococcus acidilactici and Lactobacillus plantarum. The combination of B. subtilis and L. plantarum yielded the highest efficiency of DON detoxification in bran which could reach to 75.98 in 96 h.
