Summary:
Studies have shown that the capacity to use hydrocarbons as sole carbon and energy source is very common, and not restricted to any particular group of microorganisms. Examples were found in a wide range of prokaryotic and eukaryotic genera including Gram-negative and Gram-positive bacteria, yeasts, fungi, and even some achlorophyllous algae [vanBeilen94]. One of these organisms is the Gram negative bacterium Pseudomonas oleovorans, isolated from machine shop cutting oil [Lee41], which can grow on intermediate chain length n-alkanes (C6 to C12). This pathway describes the oxidation of n-octane by this organism.

The key enzyme in this pathway is the alkane hydroxylase system, which is encoded by the OCT plasmid [Chakrabarty73]. The alkane hydroxylase system system introduces molecular oxygen in the terminal carbon atom of the hydrocarbons at the expense of NADH [Ueda72] to yield primary alcohols [Chen95]. It is composed of three components - a alkane 1-monooxygenase, a rubredoxin 2, and a rubredoxin-NAD(+) reductase. The NADH-dependent rubredoxin-NAD(+) reductase transfers the electrons from NADH, via the electron carrier rubredoxin 2, to the monooxygenase, which reduces the other oxygen atom.

The product of the hydroxylase system, octan-1-ol, is then further catabolized by an octanol dehydrogenase, an aldehyde dehydrogenase and an acyl-CoA synthetase. The final product, octanoyl-CoA, enters the β-oxidation-cycle, and can be utilized as a carbon and energy source [vanBeilen92, vanBeilen94].
