Summary of COMSTAT analysis of biomass, average thickness, and maximum thickness of wild-type strain 1291 and 1291 copA mutant biofilms grown over glass or on THCECsa
| Biofilm substrate | COMSTAT parameter | Value of parameter |
P value | |
|---|---|---|---|---|
| 1291 | 1291 copA | |||
| Glass | Biomass (μm3/μm2) | 22.0 ± 11.2 | 25.0 ± 10.9 | 0.5577 |
| Avg thickness (μm) | 82.7 ± 27.5 | 75.8 ± 23.1 | 0.5663 | |
| Maximum thickness (μm) | 102.8 ± 26.4 | 94.7 ± 26.4 | 0.4592 | |
| THCECs | Biomass (μm3/μm2) | 12.3 ± 7.3 | 11.6 ± 8.0 | 0.8224 |
| Avg thickness (μm) | 47.7 ± 22.7 | 40.5 ± 30.4 | 0.4624 | |
| Maximum thickness (μm) | 103.3 ± 27.3 | 99.3 ± 39.6 | 0.7394 | |
These experiments were performed on at least three different occasions. No statistical difference was observed, as determined using Student's t test.
