Effects of daily carvacrol (•, 1.0 mmol/h) and Spor-Klenz RTU (○, 20%) pulses on the development of dual-species biofilms compared to the untreated control (dotted line) at 25°C. A) Staphylococci. B) Salmonellae. C) Protein. Samples were collected ≤10 min after each antimicrobial pulse. Data points represent mean values of three independent experiments with standard deviations of <0.45 log CFU/biofilm for viable counts and <30 μg/biofilm for protein values. The experimental limit of detection was 2 log CFU/biofilm.
