Degradation of Long-Chain n-Alkanes by Acinetobacter Sp.

Abstract

Alkanes are widespread in nature and cause seriously pollution of environment. In many of oil pollution treatment method, because of economic, effective and less damaging to the environment and many other advantages, bioremediation technology is thought to have broad application prospects. In this study, we isolated an efficient alkane-degrading strain from some coal gasification wastewater sludge. It was identified the strain L2-4 as Acinetobacter sp.(KC211013) through morphology and 16SrDNA sequence analysis. The maximum degradation rate was aquired to 58.7% under the condition of original alkanes concentration 700mg/L, pH 7.0 and temperature 35°C. The study was designed to provide good strain resources for oil pollution remediation and microbial en hanced oil recovery.
