Comparison between the Physiological Responses of Ankistrodesmus Falcatus and Chlorella Vulgaris to Copper
The physiological and biochemical responses of two green algae Ankistrodesmus falcatus and Chlorella vulgaris to copper sulphate were investigated. In this experiment both Ankistrodesmus and Chlorella cultures were treated with copper sulphate concentrations ranging from 0. 5 to 250 µM. The influence of copper on growth and metabolism was determined. Ankistrodesmus grown at 250 µM copper sulphate, while Chlorella grown ... إقراء المزيد

Alteration in growth and physiological activities in Chlorella vulgaris under the effect of photosynthetic inhibitor diuron
In this study, we describe the effect of diuron, a photosynthesis-inhibiting herbicide, on growth, photosynthetic pigment contents, carbohydrate, protein, amino acids, proline, nitrate reductase and some antioxidant enzymes in cell suspensions of Chlorella vulgaris for seven days. The growth (cell number & dry weight) was seriously affected even with lowest diuron dose (0.1 µM). Photosynthetic pigment contents (chl-a, chl-b & ... إقراء المزيد
