Schwarz et al. in agreement with Shukla observed the formation of 2-Oxo-l, 2-dihydroquinoline, 8-hydroxy-2-oxo-l, 2-dihydroquinoline, 8-hydroxycoumarin, and 2,3-dihydroxy-phenylpropionic acid were found as intermediates of quinoline transformation by P. fluorescens 3 and P. putida 86 [325], They compared that metabolic pathway with the one obtained for Rhodococcus strain B1 (Fig. 22). This bacterium was unable to yield denitrogenated metabolites (i.e., 2-oxo-l, 2-dihydroquinoline, 6-hydroxy-2-oxo-l, 2-dihydroquinoline, and 5-hydroxy-6-(3-carboxy-3-oxopropenyl)-lH-2-pyridone).
