||Compared to many other aromatic compounds whose bacterial biodegradation has been intensively studied for decades, catabolism of fluorene is little investigated. Meanwhile, little is known of the biochemical mechanisms by which microorganisms in polycyclic aromatic hydrocarbon (PAH)-contaminated soils and other environments degrade this chemical. Such information is relevant to the development of bioremediation technologies. Transformation of fluorene by washed cells of fluorene-grown Pseudomonas sp. F274 yielded 1,1a-dihydroxy-1-hydrofluoren-9-one (up to 100 mg/l) as the stable product of angular dioxygenation of 9-fluorenone. Structural identity of the angular keto-diol was established by 13C- and 1H-NMR, gas chromatography- and direct probe-mass spectrometry. (Copyright (c) 1993 by Academic Press, Inc.)
