From: Exploring early steps in biofilm formation: set-up of an experimental system for molecular studies
Total CFU over time in adsorption mode (GW) versus planktonic culture. The LB (A,B) or SM (C,D) cultures were inoculated at 107 (A,C) or 109 (B,D) CFU/mL. One g of GW was inoculated with 5 mL of medium. After incubation, total CFU (planktonic and sessile cells) on GW were compared to CFU contained in 5 mL of planktonic culture. Each point is the mean × SD of biological triplicates. A non-linear time scale was chosen and dotted lines were drawn between experimental points for the sake of clarity.
