• Strains isolated from environmental sources such as soil, rhizosphere, sediment or sludge show a higher content of catabolic genes in their genomes compared with strains isolated from human, animal or plant hosts, but no significant difference is found among Alcaligenaceae, Burkholderiaceae and Comamonadaceae families, indicating that habitat is more of a determinant than phylogenetic origin in shaping aromatic catabolic versatility. (uai.cl)
  • In general, a genus-specific pattern of positional ordering of biodegradative genes is observed in the catabolic clusters of these pathways indicating recent events in its evolutionary history. (uai.cl)
  • In this review, the presence and organization of genes encoding oxygenases involved in aromatics biodegradation in 80 Burkholderiales genomes is analysed. (uai.cl)
  • The more widespread pathways in Burkholderiales include protocatechuate ortho ring-cleavage, catechol ortho ring-cleavage, homogentisate ring-cleavage and phenylacetyl-CoA ring-cleavage pathways found in at least 60% of genomes analysed. (uai.cl)
