EM(Effective Microorganisms)是日本琉球大学比嘉照夫教授发明的有效微生物群技术及产品,它由光合菌类、乳酸菌类、酵母菌类等三大菌群的多属多种微生物组成。通过发酵工艺将上述好氧及厌氧微生物混合培养,各微生物在其生长过程中产生有用物质及其分泌物,形成相互生长的基质和原料,通过相 EM (Effective Microorganisms) is an effective microbiota technology and product invented by Professor Ryan Kajiu of Ryukyu University in Japan. It is composed of many microorganisms belonging to the three major groups of bacteria such as photosynthetic bacteria, lactic acid bacteria and yeast. Through the fermentation process, the above aerobic and anaerobic microorganisms are mixed and cultured, and each microorganism produces useful substances and secretions during its growth to form mutually growing matrix and raw materials,
