甲烷产生菌的种类、生理生化特性及其形态,国外做了大量工作。但甲烷的纯培养应用于生产尚有一定距离。E.A.波尼—奥斯托洛夫斯卡娅把实验室中的纤维分解菌和甲烷菌的纯培养组成人工复合菌,接种发酵没有成功。说明由纯培养物组成的人工复合菌种,目前也不能在生产上应用。很多研究资料指出,沼气发酵微生物是一个极其复杂的微生物群体。McCarty认为,为了使有机物质全部转化成甲烷和二氧化碳,至少 Methanogenic bacteria species, physiological and biochemical characteristics and morphology, a lot of work abroad. However, the pure culture of methane used in production is still a certain distance. E.A. Boni - Ostolovskaya laboratories fibroblasts and pure cultivation of methane bacteria artificial composite bacteria, inoculation and fermentation was unsuccessful. Explain that the pure culture composed of artificial composite strains, at present can not be applied in production. Many research data pointed out that biogas fermentation microorganisms is an extremely complex group of microorganisms. McCarty believes that in order to make all the organic matter into methane and carbon dioxide, at least
