Continuous cultures were carried out for methane production from formate, methanol, and acetate by formate or acetate enrichment methanogenic cultures. Substratelimited chemostat cultures could be established at different dilution rates with each substrate. The growth characteristics of enrichment cultures were analysis and compared. The maximum values of specific growth rates and specific methane production rates obtained with formate, acetate, and methanol were 1.3 day^<-1> and 0.5 mol CH_4/g cell/day, 0.2 day^<-1> and 25 mmol CH_4/g cell/day and 1.0 day^<-1> and 0.20 mol CH_4/g cell/day, respectively. Substrate carbons converted to carbons of methane, carbon dioxide and cells were 22.2,70.2,and 5.6% in formate, 46,46 and 11% in acetate, and 60,20 and 13% in methanol, respectively.
