Quorum sensing provides an advantage to P.a. in coculture biofilms. (A–C Top) An x–y slice close to the attachment surface. (A–C Bottom) Three-dimensional views. (A) A coculture biofilm of wild-type P.a. and A.t. (B) A coculture biofilm of P.a.-lasRrhlR and wild-type A.t. (C) A coculture biofilm of P.a.-lasRrhlR complemented with pDA1 and wild-type A.t. Red cells, P.a., green cells, A.t. (Scale bars, 20 μm; 1 unit in 3D view = 13.4 μm.) All micrographs were taken at 164 h. (D) comstat determination of the relative amount of A.t. biofilm biomass present in pure and coculture biofilms.
