Biovolumes of Agr-ON (green bars) and Agr-OFF (orange bars) cells in biofilms of six Pagr-gfp reporter strains grown for 24 h at 25°C under flowing conditions. The percentages of Agr-ON cells are presented in parentheses. Letters indicate groups of biovolumes identified after analysis of variance (P < 0.05).
