COMSTAT analysis of phytol treated and untreated S. marcescens biofilm.
| Parameter | Control | Vehicle control | Phytol 5 μg/ml | Phytol 10 μg/ml |
|---|---|---|---|---|
| Biomass (μm3/μm2) | 20.08641 ± 0.19 | 19.68098 ± 0.4 | 14.85047 ± 0.38* | 12.06844 ± 0.63* |
| Average thickness (μm) | 19.3204 ± 0.29 | 19.12131 ± 0.59 | 14.78937 ± 0.14* | 12.1517 ± 0.51*** |
| Surface volume ratio (μm2/μm3) | 0.06664 ± 0.01 | 0.07418 ± 0.00 | 0.131617 ± 0.08 | 0.203123 ± 0.01 |
Phytol treatment (5 and 10 μg/ml) decreased the biofilm biomass, average thickness and increased the surface volume ratio of S. marcescens biofilm, compared to their untreated control. Data are expressed as mean ± SD. Student-t test was used to compare the control and treated samples.
