應用
片球菌素的分子质量约为2,700至4,000 Da。它们是潜在的食品生物防腐剂，可用于控制食源性病原体和腐败变质。
生化／生理作用
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。

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.
