FIG. 2.

Analysis of the importance of different flu orthologs for the RfaH-dependent increased biofilm formation capacity of E. coli strain 536. (A) Biofilm development of strain 536 and its derivatives in microfermentors after 24 h of growth at 37°C in M63B1 glucose medium. The results of a representative experiment are shown. (B) Average results of at least four experiments plotted as a histogram. The error bars indicate standard errors of the means. The level of biofilm formed by wild-type strain 536 (wt) was defined as 100%.
