3-hydroxyphenylacetylene (3-HPA) served as a novel, activity-dependent, fluorogenic and chromogenic probe for bacterial enzymes known to degrade toluene via meta ring fission of the intermediate, 3-methylcatechol. By this direct physiological analysis, cells grown with an aromatic substrate to induce the
