Abstract
The objective of this study was to investigate the effect of pediocin A in in vitro caecal fermentations. Pediococcus pentosaceus FBB61, ped iocin A producer (bac +) and its isogenic mutant (bac -) Fed. pentosac eus FBB61-2 were added to fermentation vessels. Pediocin A did not alt er the normal activity of caecal microflora. Nevertheless, the presenc e of pediocin A producer strain reduced proteolysis compared to the mu tant strain as indicated by ammonia concentrations (P < 0.05), and iso butyric and isovaleric molar proportions (P < 0.05).
