到 subcamersed macrophyte Hydrilla verticillata (L.f ) 的十二烷基苯磺酸钠(SDBS ) 的尖锐毒性 Royle 被学习。叶绿素内容和 3 抗氧化剂酶的活动:超级氧化物 dismutase (草皮, EC 1.15.1.1 ),过氧化氢酶(猫, EC 1.11.1.6 ),过氧物(邮政部门, EC 1.11.1.7 )在 SDBS 的不同集中下面在叶子被调查,在试验性的植物的叶子的叶绿素内容逐渐地减少了,当文化答案的电的传导性与 SDBS 的增加的剂量逐渐地增加了时。在 SDBS (32 mg/L 和 128 mg/L ) 的更高的集中下面处理,草皮在 24 h 以后完全失去了它的活动。本国的页分析显示邮政部门 isoenzymes 的差异在 SDBS 应力的不同集中下面是明显的。
The acute toxicity of Sodium dodecylbenzene sulfonate (SDBS) to subcamersed macrophyte Hydrilla verticillata (L.f) Royle was studied. Chlorophyll contents and the activities of 3 antioxidant enzymes: superoxide dismutase (SOD, EC 1.15.1.1), catalase (CAT, EC 1.11.1.6), peroxidase (POD, EC 1.11.1.7) in the leaves were investigated under different concentrations of SDBS, The chlorophyll contents in leaves of experimental plants decreased gradually, while the electrical conductivity of culture solution increased gradually with the increased dose of SDBS. Under higher concentrations of SDBS (32 mg/L and 128 mg/L) treatment, SOD lost its activities completely after 24 h. The native PAGE analysis indicated the diversity of POD isoenzymes was obvious under different concentrations of SDBS stress.
