FIGURE 3.
Anti-biofilm activity of CBG on wild-type V. harveyi (BB120). (A) CBG reduced the amount of DNA in the biofilms formed by V. harveyi. V. harveyi were grown in complete AB medium for 24 h in the presence of various concentrations of CBG, and the amount of DNA in the biofilms were quantified by real-time PCR using primers for 16S rRNA. N = 3. *p < 0.05. (B) Scanning electron microscopy of biofilms formed by wild-type V. harveyi in the presence or absence of 20 μg/ml CBG. 0.1% Ethanol (EtOH) served as vehicle control. Two different magnifications are shown (x1000 and x5000).
