Measurement of oxygen status by resazurin. Oxygen is maximal 1 to 3 h post-inoculation. While in the S. aureus mono-culture, oxgen availability decreases slowly, oxygen depletion occurs faster in co-culture with P. aeruginosa and drops to microaerophilic conditions after 13 h. Shown is the average and the standard deviation (dotted lines) of three independently performed biological replicates. RFU, relative fluorescent units (excitation/emission wavelengths)
