Multi-omics analysis of aniline-degrading bacterium, Delftia sp. K82

Abstract

Delftia sp. K82 is a soil bacterium capable of utilizing monocyclic aromatic hydrocarbons, including aniline, as its sole carbon and nitrogen source. In this study, the genome analysis of Delftia sp. K82 was completed and the genome data (6117 protein-coding genes and 62 RNA genes) were utilized for proteomic and transcriptomic analysis of Delftia sp. K82 cultured in aniline culture medium. Using these multi-omics approaches (genomics, transcriptomics, and proteomics), complete gene clusters for aniline biodegradation pathways were identified and transcriptomic or proteomic sets specifically induced in aniline culture conditions were elucidated. These data provide multi-layered information on the metabolic characteristics of Delftia sp. K82. The findings suggest that multi-omics approaches are useful analytical tools for the elucidation of the metabolic diversity of soil bacteria and for the identification of novel metabolic enzymes.
