Dissolved inorganic carbon uptake (A) and fixation (B) by T. crunogena cells after resuspension and cultivation in growth medium containing 1 mM DIC. Cells were initially cultivated in the presence of 50 mM DIC, harvested, washed, and resuspended in growth medium containing 1 mM DIC and either dimethyl sulfoxide (DMSO; 0.1% [vol/vol]) or rifampin dissolved in DMSO. Cells were harvested at the indicated times and incubated in the presence of 0.1 mM DIC for the short-term (30-s) incubations whose results are depicted here. Error bars indicate the standard errors of the measurements.
