Growth of HG001 ∆mpsABC can be complemented with 5% CO₂ and NaHCO₃. a Growth of HG001, ∆mpsABC in atmospheric (A)conditions and 5% CO₂. The growth of the mutant can also be complemented by plasmid pRB473 carrying mpsABC (compl.). Each point shown in the graph represents the mean value ± standard error mean (SEM) from three independent experiments. b Growth of ∆mpsABC in atmospheric (A) and with additions of NaHCO₃ ranging from concentrations of 1 to 50 mM, and 5% CO₂. The growth of ∆mpsABC with addition of 50 mM NaHCO₃ was similar to that under 5% CO₂, as there was no significance difference (ns) between the two conditions (p > 0.05) by unpaired two-sided t-test. Each point shown in the graph represents the mean value ± standard error mean (SEM) from two independent experiments. Source data are provided as a Source Data file
