Abstract: | Most clinical isolates identified as Pseudomonas aeruginosa grow on long-chain n-alkanes, while environmental P. aeruginosa isolates often grow on medium- as well as long-chain n-alkanes. Heterologous expression showed that the two alkane hydroxylase homologs of P. aeruginosa PAO1 (AlkB1 and AlkB2) oxidize C12-C16
n-alkanes, while two rubredoxin (RubA1 and RubA2) and a rubredoxin reductase (RubB) homologs can replace their P. putida GPo1 counterparts in n-octane oxidation. The two long-chain alkane hydroxylase genes are present in all environmental and clinical isolates of P. aeruginosa strains tested in this study.
