A Formation of pellicle biofilms by the mutants deficient in biosynthesis of exopolysaccharide EPS (∆epsD) and TasA protein fibers (∆tasA). Cells were incubated in TSB at 30 °C for 24 h before images were taken. Well diameter is 15.6 mm. B Cell numbers in dual-species biofilm. Circle dots represent B. velezensis, triangles represent P. stutzeri. Colors indicate B. velezensis strain genotypes in coculture: WT (blue), ∆epsD (pink), ∆tasA (green). Data presented are the mean ± s.d. (n = 6).
