Abstract

Eubacterium limosum grew with CO as the sole source of energy and formed acetate and CO 2 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. CO 2 stimulated growth on CO. CO was preferentially utilized when both CO and H 2 were present.
