Translational diffusion time (τ and α) parameters obtained from fitting with the equation from the fluorescent correlation curves for anionic latex beads within water and three different L. lactic biofilmsa
| Water or biofilm | τ1 (ms) | α1(%) | τ2(ms) | α2(%) |
|---|---|---|---|---|
| Water | 8.9 ± 0.6 | 92 ± 3 | >100 | 8 ± 3 |
| PRTP− | 8.7 ± 0.7 | 52 ± 9 | 177 ± 43 | 48 ± 9 |
| PRTP+ | 7.5 ± 0.7 | 38 ± 6 | 204 ± 46 | 62 ± 6 |
| PRTP* | 7.8 ± 0.7 | 36 ± 6 | 239 ± 42 | 64 ± 6 |
a
α1 and α2 are the fractions of the molar concentrations of the two diffusive species, and τ1 and τ2 are their respective translational diffusion times. Values are represented as the means ± standard errors of the means from 30 to 46 measurements from at least three independent experiments for each strain.
