Figure 6. Effect of plasmids, O-LPS, and temperature on biofilm formation.

Figure 6

Biofilm formation of different strains were compared at different temperatures: χ7122 and its plasmid derivatives strains: No-plasmids (χ7368), pChi7122-1 (χ7394), pChi7122-2 (χ7392), pChi7122-3 (χ7367), pChi7122-1,2 (χ7561), pChi7122-1-3 (χ7562), and pChi7122-2,3 (χ7274) (A), E. coli K-12 (χ6092) and its derivatives: pChi7122-1 (χ7346), pChi7122-2 (χ7347), and pChi7122-3 (χ7348) (B), and χ7122 and its LPS derivative strains : rough mutant O78(-) (χ7145), smooth strains with either O1-LPS (O1) (χ7193) or O111-LPS (O111) (χ7167) (C) at either 30°C, 37°C, or 42°C.
