The present invention relates to a novel microbial strain,
Alteromonas sp. SN2 (KCTC1 1700BP) having an activity for
degrading polycyclic aromatic hydrocarbon (PAH), a biore
mediation process of polycyclic aromatic hydrocarbon (PAH)
contaminants, comprising contacting a microbial strain
Alteromonas sp. with PAH, and a composition for purifying polycyclic aromatic hydrocarbon (PAH) contaminants, com
prising a microbial strain Alteromonas sp. It is advantageous
that the present invention may be suitably utilized in treat
ment or remediation of oil contaminants, particularly naph
thalene Soil contaminants without production of a secondary
contaminant source. As the strain and bioremediation process of this invention could be industrially utilized through low
cost and environment-friendly process, the present technol
ogy also may be carried out much more economically and
efficiently than conventional technologies Such as thermal
technology, Solidification technology, and vapor extraction
technology.
