Pseudomonas sp. strain F274, previously shown to catabolize fluorene via fluorenone and its angular dioxygenation, 2`, 3`-dihydroxy-2-carboxybiphenyl, phthalate, and protocatechuate, was examined for its ability to transform substituted fluorenes and S- and N-heterocyclic analogs. Halogen- and methyl-substituted fluorenes were metabolized to correspondingly substituted phthalates via attack on the unsubstituted ring. In the case of 1-methylfluorene, initial oxidation of the methyl group to carboxyl prevented all other transformations but 9-monooxygenation. This strain also oxidized the S-heteroatoms and benzylic methylenic groups of fluorene analogs. No angular dioxygenation of S- and N-heterocycles was observed. 24 refs., 2 figs., 1 tab.
