约在35亿年前,地球上就出现了细菌。在与人类和动植物长期的共进化过程中,彼此相互依存,相得益彰。特别是肠道内微生物与肠上皮之间相互依赖、相互作用,形成了一个动态的微生态系统。有益微生物对于保护肠道黏膜结构和屏障功能的完整性、肠道的通透性、免疫调节及正常的微生物区系发挥着重要的作用。21世纪是生物技术的时代,随着生物技术的快速发展及相关的创新型企业的不断涌现,益生菌作为微生物饲料添加剂在全球畜牧水产生产实践中的
About 3.5 billion years ago, bacteria appeared on the earth. In the course of long-term co-evolution with humans, animals and plants, they are interdependent and complement each other. In particular, intestinal micro-organisms and intestinal epithelial interdependence, interaction, the formation of a dynamic micro-ecosystem. Beneficial microorganisms play an important role in protecting the integrity of intestinal mucosal structures and barrier functions, intestinal permeability, immune regulation and normal microflora. The 21st century is the era of biotechnology, with the rapid development of biotechnology and related innovative enterprises continue to emerge, probiotics as a microbial feed additive in the world of livestock and aquaculture production practice
