FIGURE 2.
Time course of S. putrefaciens WS13 biofilm production for 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, and 132 h at 4, 15, and 30°C. The images were representative of three independent replicates. (A) Representative CLSM images of biofilm formed by S. putrefaciens WS13 after 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, and 132 h incubation. (B) Representative CLSM images of the mature biofilm formed by S. putrefaciens WS13 at 4, 15, and 30°C. (C) The biovolume of the mature biofilm at different temperature. (D) The mean thickness of the mature biofilm at different temperature. The error bar represents the standard deviation of triplicate experiments.
