摘要: 寻找抗生素替代品是养殖业面临的一大课题。片球菌(Pediococcus)是饲料添加目录中允许的益生菌之一,它是一种革兰氏阳性乳酸菌。大量研究表明,片球菌在食品、医疗和养殖行业中有着巨大的应用价值,它们在宿主肠道黏膜细胞表面具有的良好的定植能力,减少了其他细菌的黏附。同时,片球菌能够产生包括片球菌素、有机酸和过氧化氢在内的许多抗菌物质,因而在抑制病原菌生长、改善肠道微生物群落结构、刺激宿主免疫、促进养殖动物生产健康并提升动物生长性能等方面表现出良好的益生性能,但是相比较其他益生菌而言其关注程度不高。作者总结了片球菌产生抑菌物质的种类及其抑菌机制,介绍了片球菌的黏附和免疫调控作用方式,以及片球菌在猪和鸡等畜禽养殖动物生产上的应用,旨在为其在动物生产中的合理应用提供理论参考。片球菌具有广谱、稳定的抑菌效果,丰富的益生性能,它们有利于畜禽动物健康生长,预防病原菌感染,减少疾病发生,因此值得加大推广和应用的力度。

Abstract: Finding antibiotic alternatives is a major issue in the breeding industry.Pediococcus, a kind of Gram-positive lactic acid bacteria,is one of the probiotics allowed in the feed addition catalogue.A large number of studies have shown that Pediococcus has great application value in the food,medical and breeding industries.Their good colonization ability on the surface of the host intestinal mucosal cells reduces the adhesion of other bacteria.Meanwhile,Pediococcus is able to produce many antibacterial substances including pediocin,organic acids and hydrogen peroxide.Therefore,it's showing their good probiotic performance in inhibiting the growth of pathogenic bacteria,improving the intestinal microbial community structure,stimulating the host's immunity,promoting the health of farmed animals,and improving animal growth performance,However,compared with other probiotics,its degree of attention is not high.This article summarizes the types of bacteriostatic substances produced by Pediococcus and their bacteriostatic mechanisms,introduces Pediococcus's adhesion and immune regulation,and the application of Pediococcus in the production of animals such as pigs and chickens.The aim was to provide a theoretical reference for Pediococcus's reasonable application in animal production.The results discussed in this article indicated that Pediococcus had broad-spectrum,stable bacteriostatic effects and rich probiotic properties.It's beneficial to the healthy growth of livestock and poultry,prevents pathogenic bacterial infections,and reduces the incidence of diseases.Therefore,Pediococcus is worth increasing its promotion and application.

Key words: Pediococcus; pediocins; antibacterial mechanisms; probiotics; livestock breeding
