The quantitative and structural analysis of biofilm were determined using CVS and SEM respectively.
The proteomic profiles of biofilm and planktonic cells were developed.
Twenty-eight of differential expression proteins were firstly identified between biofilm and planktonic cells.
PPIase, FlgE and DsbC was expressed only in biofilm cells.
Other proteins such as LuxS, ompC, TolB, MglB were also increased in biofilm cells.
