    • Abstract


      Various anaerobic hydrolytic and methanogenic bacteria active in cattle dung biogas plants are reported in the literature. Anaerobic bacteria with ability to use volatile fatty acids constitute a vital bridge between hydrolytic bacteria and methanogenic bacteria. The present paper describes the isolation ofSyntrophobacter wolinii a propionate degrading bacterium in co-culture with a hydrogen utilizing methanogenviz.,Methanobacterium formicicum from the fermenting slurry of cattle dung biogas plant. Earlier studies on propionate and butyrate degradation indicatedMethanospirillum hungatei as the hydrogen utilizing partner of the co-culture whereas in the present studies this was not the case. Temperature 35° C, pH 7.5 and 20 mM of propionate were found optimal for growth and activity of co-culture.
