Characterization of E. coli biofilm synthesis by genetic manipulation. A The absorption of congo red with different biofilm genes in E. coli MG1655. B Comparing the amount of binding congo red with different biofilm genes in E. coli 1655. C Comparing the biofilm diameter with different biofilm genes in E. coli MG1655. D The osmotic pressure with different biofilm genes in E. coli MG1655. E The changes of CFU with different biofilm genes in E. coli MG1655. F The changes of cell growth with different biofilm genes in E. coli 1655. G Comparing the congo red staining, alcian-congo staining, and TEM with different biofilm genes in E. coli MG1655. H Comparing the different promoters to control biofilm csgA expression in E. coli 1655, “H” is high strength, “M” is medium strength, “L” is low strength. For A–D, n = 3. Error bars, mean ± s.d. Scale bar for congo staining is 1 cm, Scale bar for congo staining is 2 mm, Scale bar for Alcian-Congo staining is 5 μm, Scale bar for TEM is 1 μm
