Abstract
Cupriavidus sp. strain SK-4 is a bacterium capable of growing aerobically on monochlorobiphenyls and dichlorobiphenyls as the sole carbon sources for growth. Here, we report its draft genome sequence with the aim of facilitating an understanding of polychlorinated biphenyl biodegradation mechanisms.
Highlights
Cupriavidus sp. strain SK-4 is a bacterium capable of growing aerobically on monochlorobiphenyls and dichlorobiphenyls as the sole carbon sources for growth
Cupriavidus sp. strain SK-4 was originally isolated from Polychlorinated biphenyls (PCB)-contaminated tertiary lagoon sludge and is capable of growing on ortho-substituted CB congeners as a sole carbon source [1, 4]
The metabolic capabilities that are in dominant proportions include the metabolism of amino acids (14%), carbohydrates (14%), cofactors (8.5%), and aromatic compounds (6.5%)
Summary
Cupriavidus sp. strain SK-4 is a bacterium capable of growing aerobically on monochlorobiphenyls and dichlorobiphenyls as the sole carbon sources for growth. The utilization of microorganisms that are capable of metabolizing PCB compounds might become an efficient and less aggressive alternative for disposing of PCB pollutants [3]. Bioremediation methods often fail because of the accumulation of ortho- and para-substituted PCB compounds [1]. Strain SK-4 was originally isolated from PCB-contaminated tertiary lagoon sludge and is capable of growing on ortho-substituted CB congeners as a sole carbon source [1, 4].
