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.
