The role of sulphate reducers in the conversion of those substrates was minor although sulphate-reducing bacteria were present with a viable count similar to that of methane-producing bacteria in the sludge. Neutral spent sulphite liquor was partially converted to methane (40% of chemical oxygen demand) under these conditions. Molybdate (20 mM) inhibited methanation of both synthetic waste-water and neutral spent sulphite liquor. Acetate accumulated in glucose plus molybdate media. Molybdate had a direct inhibitory effect on enriched acetoclastic methane-producing bacteria. Molybdate was bacteriocidic to sulphate-reducing bacteria and bacteriostatic to methane-producing bacteria.
