Biochem/physiol Actions
片球菌素是一种IIa类细菌素，由 乳酸小球菌产生。它们是分子量约2700至4,000 Da的阳离子肽， 对病原菌如 单增李斯特菌、产气荚膜梭菌、粪肠球菌和 金黄色葡萄球菌表现出强烈活性。4 片球菌素的这种抗微生物活性是基于与胞质膜的相互作用，从而导致孔形成和细胞死亡。这些相互作用还会引起膜电位的变化，从而导致质子动力的损失和细胞内离子的流出，最终导致细胞死亡。 它们被证明可以抑制 单增李斯特菌。

The bacteriocin produced by Pediococcus acidilactici PAC 1.0, previously designated PA-1 bacteriocin, was found to be inhibitory and bactericidal for Listeria monocytogenes. A dried powder prepared from PAC 1.0 culture supernatant fortified with 10% milk powder was found to contain

Monoclonal antibody (MAb) R2-AR against pediocin RS2 was developed. Mice were immunized for 12 weeks with pediocin RS2 conjugated to a polyacrylamide gel. Two hybridoma fusions yielded an MAb that in Western blots (immunoblots) reacted only with pediocins RS2 and

Pediococcus pentosaceus LBM 18 has shown potential as producer of an antibacterial and antifungal bacteriocin-like inhibitory substance (BLIS). BLIS inhibited the growth of spoilage bacteria belonging to Lactobacillus, Enterococcus and Listeria genera with higher activity than Nisaplin used as control.
