Oxygen enhances biofilm development of C. jejuni NCTC 11168 and 81-176 after incubation for 24 and 48 h. (A) The CLSM images represent an aerial view of the biofilm structures in OEC (19% O₂, 10% CO₂, 71% N₂) with the shadow projection at the bottom. (B) The effect of cultivation time (24 h white bars, 48 h black bars) and OEC on biofilm formation of the two C. jejuni strains as expressed by maximum height and biomass volume. Results show the means and standard deviations of three replicates. Statistical data are presented in Supplementary Table 1.
