Screening and Separation of Dominant Biodegradation Strains for Treating Oil-field Wastewater
This paper presents a method of screening and separating specific bacterial strains for treating oil-field wastewater, which is characterized by high salinity in addition to containing oil and grease. The lab test involves two-step (primary and secondary) screening, eventually bringing forth four strains of oil-degrading microorganisms with better capacities of COD removal.
