Signal intensity analysis of OCT images of P. aeruginosa ATCC 39324 biofilms grown in LB and ASM medium. (A) Schematic presentation of P. aeruginosa biofilms grown in LB and ASM medium (see Table 1) and measured thickness and volumetric bacterial density. Note that due to growth in a CDFF, thicknesses are identical. (B) Intensity as a function of biofilm height (%) for P. aeruginosa biofilms grown in LB or ASM medium in auto-scaling analysis. (C) Same as (B), but now in re-scaling analysis. Error bars indicate standard deviations over triplicate experiments with separate bacterial cultures.
