Colony morphology and associated biofilms (measured quantitatively) produced by each <i>V. cholerae</i> strain.

<p>(A) Colony morphology: each <i>V. cholerae</i> strain was subcultured on L-agar and incubated overnight at 37°C before images were acquired; (B) Quantitative measurement of biofilm produced by each <i>V. cholerae</i> strain in nutrient-rich L-broth; and (C) Quantitative measurement of biofilm produced by each <i>V. cholerae</i> strain in nutrient-poor FSLW. All the values are expressed as means ± standard deviation (SD) from at least triplicate experiments. P-values are computed by comparing the biofilm formation of each strain with that of N1961S-24 using one-way ANOVA test. A p-value of <0.005 was considered statistically significant.
