From: Baltic Sea methanogens compete with acetogens for electrons from metallic iron
Incubations (9th transfer) replacing Fe0 with H2 as the electron donor for a Baltic-methanogens vs. b Baltic-acetogens. To generate culture conditions favorable only for Baltic-methanogens, we added kanamycin and ampicillin to inhibit the acetogens. To generate culture conditions favorable only for Baltic-acetogens, we added BES a specific inhibitor for the methanogens
