From: Role of bicarbonate as a pH buffer and electron sink in microbial dechlorination of chloroethenes
Methanogenesis and homoacetogenesis during active evolvement of reductive dechlorination. Methane (A) and acetate (C) production during reductive dechlorination in medium buffered with 2.5 (circles), 5 (triangles), 10 (squares), and 30 (diamonds) mM HCO3−. The error bars are standard deviations of triplicate cultures and the arrows represent the 2nd and 3rd addition of 8.2 mmol L−1 H2. Quantification of methanogens, Archaea (B), and homoacetogens, FTHFS (D) using qPCR. The error bars are standard deviations of triplicate analytical runs.
