FIG 6 .
Alkaline phosphatase activity exhibited by the Xylella fastidiosa-based DSF biosensor (XfDSF-biosensor strain) in cultures exposed to various concentrations of 2-cis-hexadecenoic acid (XfDSF2), 12-methyltetradecanoic acid (CVC-DSF), or both 1 µM 2-cis-hexadecenoic acid and various concentrations of 12-methyltetradecanoic acid after 96-h incubation. The error bars represent the standard errors of the means.
