Effect of sulfate on the methanogenic activity of a bacterial culture from a brewery wastewater during glucose degradation.
The maximum specific methanogenic activity (SMA) of a sludge originating from a brewery wastewater treatment plant on the degradation of glucose was investigated at various levels of sulfate on a specific loading basis. Batch experiments were conducted in serum bottles at pH 7 and 35 degrees C. A comparison of the values indicates that the SMA of this mixed culture was increased and reached its highest level of 0.128 g CH4 gas COD/(g VSS x d) when biomass was in contact with sulfate at a ratio of 1:0.114 by weight.
