甲基叔丁基醚（MTBE）是近年来在世界范围内发现的一种常见的地下水污染物，共代谢生物修复技术被认为是消除该污染物的一种有前途的方法。本论文从一株具有降解甲基叔丁基醚（MTBE）能力的细菌中分离得到一株菌株DZ 13，经16 S rRNA基因测序分析，将其命名为假单胞菌（Pseudomonassp.DZ13）。菌株DZ 13能在正构烷烃（C5-C8）上生长，并伴随着MTBE的共代谢降解。不同碳数的正构烷烃对MTBE的降解速率和叔丁醇的积累有显著影响。以正戊烷为生长基质，假单胞菌DZ 13共代谢降解MTBE时，MTBE的降解速率较高（Vmax = 38.1nmol/min/mgprotein，Ks = 6.8mmol/L），TBA的积累较低。在连续降解实验中，假单胞菌DZ 13对MTBE的去除率在连续投加5次后没有明显下降。
Co-metabolic bioremediation is supposed to be an impressive and promising approach in the elimination technology of methyl tert-butyl ether (MTBE), which was found to be a common pollutant worldwide in the ground or underground water in recent years. In this paper, bacterial strain DZ13 (which can co-metabolically degrade MTBE) was isolated and named as Pseudomonas sp. DZ13 based on the result of 16S rRNA gene sequencing analysis. Strain DZ13 could grow on n-alkanes (C5-C8), accompanied with the co-metabolic degradation of MTBE. Diverse n-alkanes with different carbon number showed a significant influence on the degradation rate of MTBE and accumulation of tert-butyl alcohol (TBA). When Pseudomonas sp. DZ13 co-metabolically degraded MTBE with n-pentane as the growth substrate, a higher MTBE-degrading rate (Vmax = 38.1 nmol/min/mgprotein, Ks = 6.8 mmol/L) and lower TBA-accumulation was observed. In the continuous degradation experiment, the removal efficiency of MTBE by Pseudomonas sp. Strain DZ13 did not show an obvious decrease after five times of continuous addition.
