Abstract: The intent of this review is to provide an outline of the microbial degradation of polycyclic aromatic hydrocarbons. A catabolically diverse microbial community, consisting of bacteria, fungi and algae, metabolizes aromatic compounds. Molecular oxygen is essential for the initial hydroxylation of polycyclic aromatic hydrocarbons by microorganisms. In contrast to bacteria, filamentous fungi use hydroxylation as a prelude to detoxification rather than to catabolism and assimilation. The biochemical principles underlying the degradation of polycyclic aromatic hydrocarbons are examined in some detail. The pathways of polycyclic aromatic hydrocarbon catabolism are discussed. Studies are presented on the relationship between the chemical structure of the polycyclic aromatic hydrocarbon and the rate of polycyclic aromatic hydrocarbon biodegradation in aquatic and terrestrial ecosystems.

Initial reactions in the oxidation of naphthalene by Pseudomonas putida
TL;DR: Radiochemical trapping experiments established that this cis dihydrodiol is an intermediate in the metabolism of naphthalene by P. putida, and a double label procedure is described for determining the origin of oxygen in the cis diHydrodiol under conditions where this metabolite would not normally accumulate.
Detoxification of polycyclic aromatic hydrocarbons by fungi
TL;DR: Although dihydrodiol epoxides and other mutagenic and carcinogenic compounds have been detected as minor fungal metabolites of a few PAHs, most transformations performed by fungi reduce the mutagenicity and thus detoxify thePAHs.
Resolution of the methane mono-oxygenase of Methylococcus capsulatus (Bath) into three components. Purification and properties of component C, a flavoprotein
TL;DR: Ion-exchange chromatography resolves the methane mono-oxygenase from soluble extracts of Methylococcus capsulatus (Bath) into three fractions that are comparatively stable at 0 degrees C, whereas fraction C is very unstable unless kept in the presence of sodium thioglycollate or dithiothreitol.
Catabolism of aromatic compounds by micro-organisms.
TL;DR: This chapter discusses the catabolism of aromatic compounds by micro-organisms, and reviews (1) enzymic degradations of di- and trihydroxy phenols, (2) reactions converting aromatic compounds into ring-fission substrates, and (3) regulation of catabolic reaction sequences.
Purification and Propeties of (+)-cis-Naphthalene Dihydrodiol Dehydrogenase of Pseudomonas putida
T. R. Patel,David T. Gibson +1 more
TL;DR: Cells of Pseudomonas putida, after growth with naphthalene as sole source of carbon and energy, contain an enzyme that oxidizes (+)-cis-1(r),2(s)-dihydroxy-1,2- dihydronaphthalenes to 1,2
