Abstract

Sphingobium sp. strain KK22 was isolated from a bacterial consortium that originated from cattle pasture soil from Texas. Strain KK22 grows on phenanthrene and has been shown to biotransform the high-molecular-weight (HMW) polycyclic aromatic hydrocarbon (PAH) benz[a]anthracene. The genome of strain KK22 was sequenced to investigate the genes involved in aromatic pollutant biotransformation.

Highlights

  • Sphingobium sp. strain KK22 was isolated from a bacterial consortium that originated from cattle pasture soil from Texas

  • Sphingobium sp. strain KK22 is a member of a bacterial consortium that was maintained on diesel fuel and benzo[a]pyrene and that mineralized high-molecular-weight polycyclic aromatic hydrocarbons (HMW PAHs) [1,2,3]

  • Strain KK22 was isolated from the consortium by phenanthrene enrichment and it was shown to biotransform the HMW PAH benz[a]anthracene to 3, 2- and single-aromatic ring products [6]
