评价了普通天胡荽作为水生植物修复重金属污染的潜力。来自营养液的碱性红46（BR 46）。在优化的实验条件下，H.普通的植物在长期重复实验条件下的连续去除能力证实了生物降解过程。因此，鉴定了许多产生的中间体化合物。人工神经网络（ANN）模型被开发用于预测生物降解效率。基于网络结果获得了预测性能（R2=0.974）。有趣的是，染料胁迫增强了超氧化物歧化酶、过氧化物酶和过氧化氢酶等抗氧化酶的活性。寻常的根和叶。发现酶反应高度依赖于植物器官和液体培养基中的染料浓度。总的来说，抗氧化酶活性的增加在根中比在叶中高得多。然而，没有显着增加丙二醛（MDA）含量检测到在根和叶中，这反映了高效率的抗氧化系统在消除活性氧。
The potential of Hydrocotyle vulgaris as an aquatic plant species was evaluated for phytoremediation of C.I. Basic Red 46 (BR46) from nutrient solution. Under the optimized experimental conditions, BR46 was removed up to 95% from incubation medium by H. vulgaris. The ability of the plant in consecutive removal under long term repetitive experiments confirmed the biodegradation process. Accordingly, a number of produced intermediate compounds were identified. An artificial neural network (ANN) model was developed to predict the biodegradation efficiency. A predictive performance (R2=0.974) was obtained based on the network results. Interestingly, dye stress enhanced the activity of antioxidant enzymes including superoxide dismutase, peroxidase and catalase in H. vulgaris roots and leaves. Enzymatic responses found to be highly depended on the plant organ and dye concentration in the liquid medium. Overall, the increase in the activity of antioxidant enzymes was much higher in the roots than in the leaves. Nevertheless, no significant increase in the malondialdehyde (MDA) content was detected in both roots and leaves which reflects the high efficiency of antioxidant system in the elimination of reactive oxygen species.
