细菌素是细菌核糖体合成产生的一类对同种或亲缘关系较近的物种具有抑制活性的活性多肽或前体多肽,具有无毒、无害、无残留、耐高温、安全有效和无细菌耐药性等优点,目前是人们的关注焦点。研究主要阐述近几十年有关细菌素的研究进展及其在动物饲料中的应用,并对其应用前景提出展望。 Bacteriocins are a class of active polypeptides or precursor polypeptides that are produced by the synthesis of bacterial ribosomes and have inhibitory activity against more or less closely related species of the species or species. They are non-toxic, harmless, non-residue, thermostable, safe and effective, Drug resistance, etc., is currently the focus of attention. The research mainly expounds the research progress of bacteriocin in recent decades and its application in animal feed, and puts forward the prospect of its application.
