从反硝化生物滤池反应器中分离到一株假黄单胞菌（Pseudoxanthomonas，N4）。考察了该菌对邻苯二甲酸二（2-乙基己基）酯（DEHP）的降解能力和反硝化能力。结果表明，N4菌株能利用DEHP作为碳源和能源。菌株N4在较宽的pH和温度范围内表现出良好的DEHP降解能力。DEHP降解的最佳温度和pH值分别为32 ℃和6.0。N4菌株降解DEHP的动力学为指数型。菌株N4具有反硝化能力，能还原硝酸盐和亚硝酸盐，但不以DEHP为碳源。(C)2014爱思唯尔有限公司版权所有。
A bacterial strain (designated as N4) of Pseudoxanthomonas was isolated from a denitrification biofilter reactor. This study examined its degradation capability of di(2-ethylhexyl) phthalate (DEHP) and its denitrification ability. All results showed that, strain N4 could use DEHP as a carbon and energy source. Strain N4 demonstrated good DEHP degradation ability over a broad pH and temperature range. The optimal temperature and pH for DEHP degradation were 32 degrees C and 6.0, respectively. The kinetics of DEHP degradation by strain N4 were exponential in nature. Strain N4 showed denitrification ability and could reduce nitrate and nitrite but not with DEHP as its carbon source.
