The effects of substrate composition on the characteristics of substrate removal and biofilm formation in methanogenic phase of anaerobic two phase digestion were investigated by using laboratory-scale anaerobic fluidized bed reactor with packed media of activated carbon. Three kinds of substrates were used. The first one was composed of acetic acid, propionic acid and butyric acid. A small amount of yeast extract or glucose was added to the second and third ones, respectively. In the experiments in which yeast extract of glucose was added to the mixed acid substrates, the substrate removal efficiencies were higher than that in the experiment using acetic acid substrate. The biofilm formation was accelerated by using the mixed substrate to which yeast extract was added.The mechanism of attachement of anaerobic bacteria to packed media was studied by the observation on the seperative condition of bacteria after n-hexadecane was added to the cultures.

采用实验室规模的活性炭填料厌氧流化床反应器，研究了基质组成对厌氧两相消化产甲烷相基质去除特性和生物膜形成的影响。使用了三种基质。第一种由乙酸、丙酸和丁酸组成。将少量酵母提取物或葡萄糖分别添加到第二和第三个中。在混合酸基质中添加葡萄糖酵母提取物的实验中，基质去除效率高于使用乙酸基质的实验。采用添加酵母膏的混合基质促进生物膜的形成，通过观察添加正十六烷后厌氧细菌的分离情况，探讨了厌氧细菌在填料上的附着机理。
