Flagellar motility during e. coli biofilm formation provides a competitive disadvantage which recedes in the presence of co-colonizers

HIGHLIGHTS

SUMMARY

In these threedimensional structures, the aggregated cells prosper in a self-produced polymer extracellular matrix that protects them from shear stress, grazers and biocides (Hall-Stoodley et_al, 2004; Karygianni et_al, 2020). Early research determined that motility was crucial for biofilm development in Pseudomonas aeruginosa (O`Toole and Kolter, 1998), Listeria monocytogenes (Lemon et_al, 2007) and Escherichia coli (Pratt and Kolter, 1998; Wood et_al, 2006). Motility per se can support aerotaxis, inducing interface accumulation which indirectly promotes biofilm formation (O`Toole and Kolter, 1998; Suchanek et_al, 2020). This happens only at a reduced distance of . . .
