Pan-Genomic and Phenotypic Characterisation of Petroleum Hydrocarbon Degradation by Pseudomonas Species.

ABSTRACT: Pseudomonas, a cornerstone genus in petroleum hydrocarbon bioremediation, exhibits remarkable metabolic diversity. To systematically decipher the genetic basis of this trait, we constructed a curated collection of representative Pseudomonas strains with documented degradation capabilities through a bibliometrics-driven approach. Comparative genomic analysis revealed that these strains possess a rich repertoire of genes linked to petroleum hydrocarbon degradation, including those encoding key enzymes such as monooxygenases, dioxygenases, alcohol dehydrogenases, cytochrome P450, ferredoxins, and regulatory proteins (e.g., LuxR, AraC, GntR). Among the strains examined, P. citronellolis and P. putida contained the highest abundance of such genes. The accessory genome size varied considerably a
