Growth and whole cell CO₂ fixation rates of WT2321, strain Ω∷RLP and strain Ω∷SDR

Strain	Doubling time* growth condition			Whole cell CO2 fixation† growth condition
	CO2	CO2 + acetate	CO2 + Cys	CO2	CO2 + acetate + pyruvate
WT2321	2.0  ± 0.3	1.9  ± 0.3	ND‡	1,719	514
Ω∷RLP	7.7  ± 2.0	2.9  ± 0.6	2.7  ± 0.4	599	319
Ω∷SDR	1.9  ± 0.3	ND	ND	ND	ND

^*Doubling time in hours. Data are the mean ± standard deviation from three to five independent cultures for each condition. Starter cultures were from the same growth condition and were in mid- to late-logarithm phase (12–16 h old, <100 μg protein ml⁻¹). Cultures were inoculated to a density of 2–4 μg protein ml⁻¹. 

^† nmol CO₂ assimilated (min⋅mg protein)⁻¹. Data is the average of two independent log phase cultures. 

^‡ ND, not determined.
