Biodegradation Characteristics of DBP by Elizabethkingia sp. DBP-WUST
Abstract：A strain (DBP-WUST), which could highly utilize DBP as the sole carbon and energy source, was isolated from the active sludge in the refinery wastewater treatment plant of Sinopec Wuhan Petroleum Group Co. Ltd. According to the morphological observation, physiological and biochemical tests, and sequence analysis of 16S rDNA, the strain was identified as Elizabethkingia sp. The optimal temperature, initial pH, shaker rotary speed, and saturation inoculation dosage for strain DBP-WUST uti- lizing DBP was 35 ℃, pH7, 150 r/min and 7%, respectively. The experiments of DBP degradation by the pure culture showed that DBP of 400 mg/L could be degraded completely in 60 h under the optimal growth conditions. Furthermore, the COD of the waste-water could excellently be removed after the strain was added to the actual refinery waste-water.
