Notes: Bicarbonate and CO2 gas were added to methanogen as a carbon source. Acetate was added to sulfate-reducing bacteria as a carbon source (final concentration = 2 mm). Yeast extract and pepton were added to heterotroph as a carbon source. * = difficulty in determining between microorganisms or minerals. † = microorganisms were observed in the culture bottle. ND = not detected.
