Effect of carvacrol on viability and protein mass of dual-species biofilm formation by S. aureus and S. enterica serovar Typhimurium
| Biofilm stage | % Changea in biofilm viability (log CFU/biofilm) and mass (μg/biofilm)

||
|---|---|---|---|
| S. aureus | S. enterica serovar Typhimurium | Protein | |
| Planktonic | −99.5 | −98.5 | −29.2 |
| Adherent | 49.9 | −65.9 | −89.3 |
| Microcolony formation | 191.6 | −76.1 | −63.3 |
| Microcolony coalition | 35.6 | −14.9 | −57.1 |
| Proliferation | −34.3 | −46.0 | −61.0 |
| Maturity | −23.4 | −97.5 | −66.0 |
| Quasi-steady-state matrix | −79.5 | −13.9 | −52.8 |
a
Difference between viable counts or total protein content before and after pulsing with carvacrol. Biofilm stages were categorized based on visualization of morphological and developmental states during film formation on a steel surface. The data represent a conglomerated summary of the results obtained during this study.
