Methods
E. coli K-12 was cultured at 37 °C for 24 h and diluted to a final concentration of 1.4 X108 CFU/mL
Experimental samples consisted of 60 polystyrene beads in 90 ml of 0.85% saline mixed with 125 ml of E. coli suspension
Bacterial experiments were set up for Microgavity & Ground-Control conditions
Microgravity experiment was on the Endeavour for 15 days, 17 hours
Samples were observed using a Scanning Electron Microscope (SEM).
Biofilms were located and measured by length, width, and thickness using the SEM measuring tool

Biofilm - Wikipedia https://en.wikipedia.org/wiki/Biofilm A biofilm is any group of microorganisms in which cells stick to each other and often these cells adhere to a surface. These adherent cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS).
