Growth of, and CO consumption by, bacterial strains. When determining statistically significant consumption of CO during CO tolerance experiments, one-way ANOVA was used to compare all timepoints within a given concentration. A) Growth of C. ulmosensis CV2^T with 5 mM pyruvate combined with varying concentrations of headspace CO (0–10,000 ppmv) (OD₆₀₀). B) Headspace CO (% remaining vs. timepoint 0) during growth with 5 mM pyruvate by C. ulmosensis CV2^T. C) Growth of Pb. terrae COX with 5 mM pyruvate combined with varying concentrations of headspace CO (0–10,000 ppmv) (OD₆₀₀). D) Headspace CO (% remaining vs. timepoint 0) during growth with 5 mM pyruvate by Pb. terrae COX. Bars represent mean values with standard deviation of independent triplicate incubations for each substrate
