Abstract

Forty isolates of bacteria were isolated from the wastewater system of Sarir Refinery. All isolates were cultivated in liquid media with crude oil as a sole carbon and energy source.
Four bacteria isolates (D2, S3, S11 and S12) were identified as Cellulosimicrobium cellulans, Brevibacterium liquefaciens, Brevibacterium mcbrellneri and Enterococcus saccharolyticus, respectively.
The results concluded that C. cellulans (D2), E. saccharolyticus (S12) and B. liquefaciens (S3) have the potential to be used in bioremediation of crude oil because they showed good growth on hydrocarbons.
