The effect of some Lactobacillus strains on deoxynivalenol biodegradation

Abstract

Purpose

Some useful bacteria could be used regularly in mycotoxins biodegradation. It is a very good and ecological method, which was tested in experiments when lactobacilli were used. The paper aims to describe this.

Design/methodology/approach

Five strains of lactobacilli in experiments were shown, by direct enzyme‐linked immunosorbent assay (CD‐ELISA) test after their growth in MRS broth, to have decreased in the amount of deoxynivalenol (DON) measured by spectrophotometer. Free DON in the samples and control is allowed to compete with enzyme‐labeled DON (conjugate) for the antibody binding sites. The test was read in a microwell reader to yield optical densities.

Findings

It was found that Lactobacillus plantarum, Lactobacillus rhamnosus and Lactobacillus fermentum were more active than human strain Lactobacillus casei Shirota.

Originality/value

The paper suggests that other lactobacilli should be tested in this research field and could be used for detoxification of some feed kinds contaminated minimally by DON.
