3/6/2010, · Theoretically, wastewaters with a COD/sulfate ratio of 0.67 or higher contain enough COD (electron donor) to remove all sulfate by sulfate-reducing bacteria. If the ratio is lower, addition of extra COD, for example, as ethanol or synthesis gas (a mixture of H 2 , CO 2 , and CO) is required.

Desulfobulbus sp. seemed to be important in reactors with carbohydrates and/or volatile fatty acids containing wastewater. In the presence of sulfate these bacteria could play a role in propionate degradation, while in the absence of sulfate they might play a role in lactate and ethanol fermentation.

concrete in wastewater systems has been recognized since 1945. Parker1 described the role of an acid producing bacterium that he called Thiobacillus concretivorous, which he had isolated from corroded concrete from a Melbourne, Australia sewage system. Th. concretivorous was described as a sulfate reducing bacterium (SRB)
