Table 3.

The calculated time constant by analyzing Fig. 6.

Substrate Time constant (s) for S. aureus Time constant (s) for E. coli O157:H7
-C2NH2 112.4 ± 8.8 187.4 ± 33.9
-C15COOH 18610 ± 3093 74415 ± 90733
-C7CH3 15680 ± 1395 47210 ± 9614
-C9CH3 12590 ± 2982 29270 ± 2328
-C17CH3 9757 ± 1777 26890 ± 4387

The parameters were obtained based on the exponential-decay characterizing a first-order adhesion process all substrates except amino-terminated one, where the diffusion time constant was calculated from Equation 1.
