The objective of this study was to investigate the effect of pediocin A in in vitro caecal fermentations. Pediococcus pentosaceus FBB61, pediocin A producer (bac+) and its isogenic mutant (bac-) Ped. pentosaceus FBB61-2 were added to fermentation vessels. Pediocin A did not alter the normal activity of caecal microflora. Nevertheless, the presence of pediocin A producer strain reduced proteolysis compared to the mutant strain as indicated by ammonia concentrations (P < 0.05), and isobutyric and isovaleric molar proportions (P < 0.05).
本研究的目的是调查片球菌素A在体外盲肠发酵中的作用。将戊糖片球菌FBB61（片球菌素A产生菌，bac+）及其同基因突变体（bac-）戊糖片球菌FBB61-2添加到发酵容器中。片球菌素A未改变盲肠微生物群的正常活性。然而，如氨浓度（P<0.05）、异丁酸和异戊酸摩尔比例（P<0.05）所示，与突变菌株相比，片球菌素A产生菌的存在降低了蛋白水解作用。
