From: Role of bicarbonate as a pH buffer and electron sink in microbial dechlorination of chloroethenes
Chloroethenes dechlorination at different HCO 3 −concentrations. Time course of chloroethenes dechlorination to ethene in cultures amended with H2 as the sole electron donor and with HCO3− buffer (graphs A, C, E, and G) and a combination of HCO3− and HEPES buffers (graphs B, D, F, and H). The arrows represent the 2nd and 3rd addition of 8.2 mmol L−1 H2. The error bars are standard deviations of triplicate cultures.
