The enzymes responsible for the oxidation of n-octane to octanoic acid or beyond in Pseudomonas oleovorans are octane inducible and are coded by genes borne on a transmissible extrachromosomal element. The octane to octanoate enzymes induced by octane are repressed by octanol. The chromosome also carries genes coding octanol oxidation enzymes that, in contrast, are induced by octanol, not by octane. The octane plasmid has been transferred from P. oleovorans to several other fluorescent Pseudomonas species. In exconjugants, the presence of both octane and camphor plasmids enhances their segregation rate.
在食油假单胞菌中，负责将正辛烷氧化为辛酸或进一步氧化的酶是辛烷诱导型的，由存在于可传递的染色体外元件上的基因编码。由辛烷诱导产生的将辛烷转化为辛酸的酶会被辛醇抑制。染色体上也携带编码辛醇氧化酶的基因，相反，这些酶是由辛醇诱导产生的，而非辛烷。辛烷质粒已从食油假单胞菌转移到其他几种荧光假单胞菌属细菌中。在接合后体中，辛烷质粒和樟脑质粒的同时存在会提高它们的分离率。
