FIG. 3.

Effect on culturability of carbon-starved Vibrio sp. strain S14, assessed by CFU (A) and growth rate of Vibrio sp. strain S14 assessed by OD (B) after the addition of furanone-2 (closed circles) and furanone-3 (triangles) at 5 μg ml⁻¹. Open circles denote control cultures without the addition of furanones. Experiments were repeated at least three times, each time in triplicate. The results presented are average values of the triplicate data from a representative experiment.
