Última Evaluation of microorganisms with sulfidogenic metabolic potential under anaerobic conditions BABT Sakamoto,Isabel Kimiko; Maintinguer,Sandra Imaculada; Hirasawa,Julia Sumiko; Adorno,Maria Angela Tallarico; Varesche,Maria Bernadete Amâncio. The aim of this work was to identify groups of microorganisms that are capable of degrading organic matter utilizing sulfate as an electron acceptor. The assay applied for this purpose consisted of running batch reactors and monitoring lactate consumption, sulfate reduction and sulfide production. A portion of the lactate added to the batch reactors was consumed, and the remainder was converted into acetic, propionic and butyric acid after 111 hours of operation These results indicate the presence of sulfate-reducing bacteria (SRB) catalyzing both complete and incomplete oxidation of organic substrates. The sulfate removal efficiency was 49.5% after 1335 hours of operation under an initial sulfate concentration of 1123 mg/L. The SRB concentrations...
