Abstract:
有机氯农药曾在世界范围内被广泛用于农业害虫的防治，为利用表面活性剂增效修复技术去除环境中的有机氯农药污染，研究了3种非离子表面活性剂（tween80、tween20和tritonx-100）对4种典型有机氯农药（4,4’-ddt、狄氏剂、艾氏剂和七氯）在水相中的增溶作用，对白腐菌phlebiaacanthocystistmic34875生长的影响以及对该菌株、胞外及胞内酶降解有机氯农药的强化效果.增溶试验结果表明，3种非离子表面活性剂可明显增加各有机氯农药的水溶解度，其增溶能力大小顺序为tween80>tween20>tritonx-100.tween80在低浓度（0.05、0.1和0.2gl-1）下会促进白腐菌在pdb培养基中的生长，使其生物量增加；而高浓度（0.5和1.0gl-1）的tween80则对菌株的生长产生一定的抑制作用.在0.05-0.5gl-1浓度范围内，tween80可强化菌株对有机氯农药的降解效果，且降解率随着tween80浓度的增加而增加.降解强化效果在tween80浓度为0.5gl-1时达到最佳，4,4’-ddt、狄氏剂、艾氏剂和七氯的降解率相比对照分别提高了6.70%、6.37%、10.94%和7.21%.tween80同样可促进胞内酶和胞外酶对4种有机氯农药的降解，尤其是对胞外酶降解的强化作用，在1.0gl-1的tween80溶液中，有机氯农药的降解率提高了10%左右.可见，在农药污染环境的生物修复技术中，应用tween80等非离子表面活性剂来提高修复效率是可行的.
