Figure 2. Biofilm formation in nine prophages deletion strains.

Early (A,C,E) and late (B,D,F) biofilm formation of E. coli K-12 BW25113 and nine isogenic prophage deletion mutants were tested in two different media (LB or M9C-glu) at two different temperatures (37 °C or 30 °C), respectively. Each data point is the average of at least ten replicate wells from two independent cultures, and one standard deviation is shown here from (A–F).
