Real-time gas exchange rates in suspension and immobilized cells. A Average steady state net O₂ evolution; B net CO₂ yield; C dark O₂ consumption. The cells were incubated in BG11 supplemented with NaCl and 1 mM IPTG (+ NaCl) to induce sucrose production. As a negative control the cells were incubated in BG11 medium supplemented with 1 mM IPTG, but not NaCl (-NaCl). Error bars represent the standard deviation of three independent biological replicates. Statistical significance between cultures in medium with and without NaCl is marked by * (P = 0.006–0.04)
