微生态制剂(Microbiol ecological agents)是Parker(1974)提出的与“抗生素”相对的新概念,指从动物或自然界分离或通过生物工程人工构建的有益微生物,经培养、发酵、干燥、加工等特殊工艺制成的含有活菌或包含细菌菌体及其代谢产物的制剂。其主要是根据微生态理论,用正常微生物菌群及其代谢产物,用以补充和扶持宿主的正常生理活性,调整微生态失调,维持微生态平衡,以达到调整动植物微生态平衡的目的。
Microbiol ecological agents are new concepts proposed by Parker (1974) as opposed to “antibiotics” and refer to beneficial microorganisms isolated from animal or nature artificially constructed by bioengineering, cultured, fermented, dried and processed Such as special processes made of live bacteria or bacterial bacteria and their metabolites containing preparations. It is mainly based on the theory of micro-ecology, the use of normal microbial flora and its metabolites to supplement and support the host’s normal physiological activity, adjust the micro-ecological imbalance and maintain micro-ecological balance in order to achieve the purpose of adjusting the micro-ecological balance of animals and plants.
