FIG. 8.

Cell attachment patterns and displacement kinetics of a ΔpgaC mutant of TR1-5. The culture was grown for 4 h in CFA medium at ambient (∼24°C) temperature, slides were assembled, and photographs were taken immediately (A), 20 min (B), and 60 min (C) later. FFT spectra are shown to the right of the corresponding images. Cell density versus time under gravitational field was calculated as in Fig. 2 and is shown for the top and bottom surfaces of the slide assembly in panel D.
