从焦化废水厂的活性污泥中采用"邻苯二酚-石油烃"双底物驯化获得石油烃的专性降解菌系,在最佳环境条件下研究其对石油污染土壤的修复性能.高通量测序分析显示,驯化后的专性菌系以产黄杆菌属(Rhodanobacter sp.)为主,占比41%.... 从焦化废水厂的活性污泥中采用"邻苯二酚-石油烃"双底物驯化获得石油烃的专性降解菌系,在最佳环境条件下研究其对石油污染土壤的修复性能.高通量测序分析显示,驯化后的专性菌系以产黄杆菌属(Rhodanobacter sp.)为主,占比41%.最适降解温度为30~35℃,最佳pH值为7~8.聚山梨酯-80(吐温80)可作为碳源促进专性菌系的生长,提高石油烃的降解效率,并且添加吐温80比十二烷基硫酸钠(SDS)更利于石油烃的降解.研究表明,当吐温80的浓度为5CMC(即375mg/L)时,石油烃的降解效率最高.在最佳环境条件下,为期80d修复试验,构建的专性菌系石油烃降解效率稳定在77%,这证实了双底物驯化模式获得的专性菌系对石油污染土壤具有良好的修复性能. 展开更多

Environmental pollution is a by product of industrialization when economy of a region is developing. China also suffers from such a problem, especially in the southern part like Suzhou region in Jiangsu Province. In this paper, data covering situations of surface water pollution and social and economic development showed that the surface water pollution in Taicang County, a typical economic zone of Suzhou region, is significantly correlated to the economic growth of this region. 展开更多
