Analyses of EPS and bacteria in E. coli D5 biofilms treated with linalool for 24 h. (A) Confocal laser scanning microscopy (CLSM) images of linalool at 0, 1, and 2 µL/mL linalool; green, EPS, and red, bacteria; Representative are the 20 μm bars on images derived from three independent replicates. (B) Biomass of EPS in the biofilm. (C) Biomass of bacteria in the biofilm. A specimen of 0 µL/mL linalool was employed as a control. Data represent the mean ± SD of three separate experiments. Different lower cases indicate significant differences, and adjacent letters indicate significant variations compared to previous data (p < 0.05). Indirect letters manifest greatly significant variations (p < 0.01)
