    • ‘After overnight incubation in selective media, recombinants were plated onto MM agar containing 20 g/ml kanamycin and maintained at 25°C in a sealed gas jar under microaerophilic conditions.’
    • ‘When O2 is supplied to the cells under the microaerophilic conditions, the aerobic respiration will be stimulated.’
