Growth curve (left) and pH changes in cultures (right) of V. cholerae strains in glucose-Supplemented Media. (a) Classical biotype strain O395, (b) Wave 1 prototype El Tor strain N16961, (c) Wave 2 atypical El Tor strain B33, and (d) Wave 3 atypical El Tor strain IB5230. Glucose was added to LB media at 0% (filled circle), 0.5% (circle), 1.0% (inverted filled triangle), and 1.5% (inverted triangle). Three independent experiments were performed. Values of mean ± standard deviation (viable cell count) and a representative result (pH) are shown.
