外文摘要：The objective of this study was to determine the effects of a high salt culture medium (fish sauce and salted fish) on the detoxification capacity of Lactobacillus acidophilus (L.a), L. bulgaricus (L.b), and L. casei (L.c). These lactic acid bacteria (LAB) strains were mixed with dried fish and fish sauce containing aflatoxin B1 (AFB1) and T-2 toxin (T-2) and cultured at room temperature for 24 h. The toxin concentrations in the media were quantified using LC-MS/MS following the incubation. Compared with the MRS broth, the growths of L.a, L.b, and L.c were inhibited in the salted fish and fish sauce media. As the toxin concentration in the MRS broth increased, the toxin removal rates for L.a, L.b, and L.c increased, especially those for the mixed L.a, L.b, and L.c (L.abc). Moreover, the abilities of L.a, L.b, and L.c to remove AFB1 in the MRS broth was significantly stronger than that for T-2, indicating the mycotoxin toxicity enhanced the detoxification ability of LAB. Unlike the MRS broth, salted fish and fish sauce can enhance the removal rates of T-2 for L.a, L.b, and L.c. This indicates that high-salt stress could promote the synthesis of a detoxification factor in LAB. ? 2020 Elsevier Ltd
