Nitrate-dependent oxidation of lactate (A, C) or sulfide (B) by newly isolated oil field NRB Sulfurospirillum sp. strain KW (A, B) and Thauera sp. strain N2 (C). Concentrations of nitrate (), nitrite (), ammonium (), lactate (), acetate (), sulfide () and sulfate (), as well as Eh (----) are shown. All batch cultures were done in duplicate, with average deviation shown when error bars exceeded the size of the symbols.
