“…Monooxygenases which behave in an analogous fashion have been found in a variety of organisms, including methanotrophs (Leadbetter 8z Foster, 1960;Colby et al, 1977;Hou et al, 1981) and liquid n-alkane utilizers (Fredricks, 1967;Klein et af., 1968;Klein & Henning, 1969;Grossebuter et al, 1979). Interestingly, such organisms have often been found to catalyse the conversion of alk-1-enes to the 1,2-epoxyalkane (May & Abbott, 1972;Colby et al, 1977;Hou et al, 1979) like strain B3aP.…”

Several strains of propane-utilizing bacteria were isolated from samples of pond and river water. They could be classified into three groups according to their ability to grow on acetone, and a representative strain from each group was selected for detailed study. All three strains belonged to the genus Arthrobacter. Strain B3aP could not grow on acetone and could not oxidize acetone after growth on propane. Strain PrI03 grew slowly on acetone but could not oxidize acetone after growth on propane. Both strains excreted acetone during growth on propane. Simultaneous adaptation experiments demonstrated that, whilst propane was oxidized to both propan-1-01 and propan-2-01, only propan-l-ol was metabolized completely suggesting that only the terminal oxidation pathway was involved in propane dissimilation. The third strain, B2, grew rapidly on acetone and was induced for acetone oxidation after growth on propane, suggesting that both propan-l-ol and propan-2-01 were produced and metabolized completely since no products of propane oxidation could be detected in culture supernatants. We compare these findings with previous reports concerning pathways of propane oxidation.

“…Although the mutant produced small quantities of both dimethylphenol isomers, it is probable that the 3,4-isomer was formed by a side reaction during the initial oxygenase-catalysed reaction. There are precedents for such side reactions in monooxygenase-catalysed reactions, since a number of micro-organisms can hydroxylate aliphatic and aromatic hydrocarbons at more than one carbon atom, even though only one of the hydroxylated products is metabolized fully (Fredricks, 1967;Klein & Henning, 1969;Grossebuter et a/., 1979;Stephens & Dalton, 1986;Shields et al, 1989).…”

An o-xylene-utilizing Rhodococcus, strain B3, was isolated from enrichments with o-xylene. The pathway for o-xylene degradation was investigated by simultaneous adaptation experiments, studies of product formation by a mutant and fortuitous oxidation studies using trimethylbenzene isomers as substrates. Two pathways were found to operate simultaneously and both were inducible. The first pathway involved the oxidation of a methyl group to form 2-methyl benzyl alcohol, followed by oxidation via the corresponding acid to 3-methylcatechol. The second pathway involved oxidation of the aromatic ring to form a dimethylcatechol. The bulk of the evidence suggests that the initial reaction was catalysed by a monooxygenase rather than a dioxygenase, and that 2,3-dimethylphenol was produced as an intermediate.
