Growth of Eubacterium limosum with Carbon Monoxide as the Energy Source

Genthner, B. R. Sharak

RESUMO

Eubacterium limosum grew with CO as the sole source of energy and formed acetate and CO2 as the major products. The generation time on CO was 7 h. Uninhibited growth occurred in cultures containing 50% CO or less, but growth occurred at all concentrations tested (i.e., up to 75% CO). The pH optimum for growth was 7.0 to 7.2, whereas growth was poor at a pH below 6.7. CO2 stimulated growth on CO. CO was preferentially utilized when both CO and H2 were present.
