ABSTRACTDeoxynivalenol (DON) poses a health risk to animals and humans consuming contaminated food and feed. Currently, no effective method had been established to detoxify DON. Obtaining strains for the detoxification of DON from probiotic strains and ascertaining the mechanisms of detoxification will be helpful for assuring food safety in food processing. In this research, two Bacillus strains possessing the capability of detoxifying DON were picked out from 59 probiotics by using a two‐run screening. The strategy of adjusting pH and eightfold dilution was successfully applied to eliminate the interferences caused by MRS and nutrition broth in DON determination in competitive indirect enzyme‐linked immunosorbent assay (ELISA)...
To study the antibiotic susceptibility of eleven vaginal probiotic lactobacilli, the disc diffusion method in LAPTg agars was performed. The results had shown that all strains were resistance to tobramycin, lomefloxacin, nalidixic scid, ofloxacin, enoxacin, ciprofloxacin, norfloxacin and fleroxacin. Thereof eight were resistance to sparfloxacin, six were resistance to gentamicin and netilmicin. All...
