Fig 3. Biofilm formation of C. tropicalis in the presence or absence of IAA.

a) C. tropicalis (1 x 10⁷ cells/mL each) grown on PDA plates for 24 h in the presence or absence of IAA and colony forming units (CFUs) were counted. The results are the means from triplicate experiments and error bars indicate the means ± standard deviations. * denotes statistical significance, p-value < 0.05. b) Representative SEM images of C. tropicalis grown in the presence or absence of IAA, confirming that the addition of IAA promoted the formation of biofilms.
