O2 and N2O profiles from alginate-encapsulated P. aeruginosa. a P. aeruginosa cultured under normoxic conditions (circles) and anoxic conditions with 10 mM NO3− (triangles). Furthermore, a control measurement of N2O on alginate-encapsulated P. aeruginosa grown without NO3− (asterisk). b P. aeruginosa cultured under normoxic conditions supplemented with 10 mM NO3−. O2 profiles (circles) and N2O profiles (triangles). Bars represent average ± standard deviation from 3 to 4 replicates. All measurements were performed at 37 °C in growth medium
