Abstract

Abstract:

In order to study absorption characteristics and mechanisms of Lactobacillus plantarum to aflatoxin B1 (AFB1), 14 strains with absorption capability to AFB1 were screened in vitro. Lactobacillus plantarum F22 exhibited the highest absorption to AFB1. Effects of F22 under various incubation times, heating-treatment, mimic gastric intestinal environment treatment, and lyophilization processing on absorption rate to AFB1 were also investigated. Incubation of F22 and AFB1 for 30 min showed the highest absorption (P＜0.01). Heating-treatment promoted absorption capability to AFB1 (P＜0.01). In contrast, mimic gastric intestinal environment caused a significant decrease in absorption to AFB1 (P＜0.05) and no significant effect on absorption to AFB1 was observed during lyophilization processing (P＞0.05). Absorption capability of Lactobacillus plantarum to AFB1 was strain-dependent due to the composition and structure of cell wall.

Key words: Lactobacillus, AFB1, screening, absorption
