ABSTRACT:
Alkane-utilizing bacteria are used to degrade pollutants comprising petroleum compounds. In-situ or ex-situ techniques may be used to reduce or eliminate petroleum pollutants from liquid, gas and solid sources. In a preferred embodiment, petroleum concentrations in various environments are reduced by contacting the petroleum pollutants with butane-utilizing bacteria in the presence of oxygen to degrade the petroleum pollutants by cometabolism or direct metabolism. Suitable alkane-utilizing bacteria include Pseudomonas, Variovorax, Nocardia, Chryseobacterium, Comamonas, Acidovorax, Rhodococcus, Aureobacterium, Micrococcus, Aeromonas, Stenotrophomonas, Sphingobacterium, Shewanella, Phyllobacterium, Clavibacter, Alcaligenes, Gordona, Corynebacterium and Cytophaga.
