There have been isolated crystalline products, B-A, B-B and C, the first from Pseudomonas aeruginosa T 359 culture broth containing bouillon-CaCl_2,the second and third from culture broth containing peptone-CaCl_2,in addition to pyoluteorin, pyocyanine, phenazine-1-carboxylic acid, oxychlororaphine and anthranilic acid.On benzoylation, the product B-A gave a monobenzoate which melts at 155℃. From the physiochemical examination, it was presumed that the product B-B is a mixture containing 2-n-heptyl-4-quinolone, 2-n-nonyl-4-quinolone and 2-n-nonenyl-4-quinolone and that the product B-A is 2-n-heptyl-3-hydroxy-4-quinolone which might be derived from 2-n-heptyl-4-quinolone by biological hydroxylation and that the above mentioned monobenzoate is 2-n-heptyl-3-benzoyl-4-quinolone, whereas the structure of the product C, C_<10>H_7NO_4,is not yet certain.
