Survival (%) of the alga was reduced with the increasing concentrations of mercury. Of these five amino...

Due to climatic changes in tropics, saline water bodies are often subject to natural fluctuations of salinity through precipitation, dessication, drought conditions or anthropogenic interference. Growth and persistence of algae under these conditions require physiological tolerance and/or resistant stages in the life cycle. Salinity, which ranges f...

Heavy metals are the pollutants of major concern because they concentrate within the organism to a level greater than that in the environment and remain persistent for long period. Ironically in many of the fresh water bodies especially in the rivers and lakes the human input of these unwanted elements is many times greater than the natural inflow...

The effect of mercury on Chlorella vulgaris is influenced to a large extent by organic carbon sources like glucose, glutamate, and 2-oxoglutarate which is exhibited through changes in growth and metabolic processes of the alga in the presence of static dose (0.200 +/- 0.004, p = 0.05) of Hg2+. Addition of the three carbon sources to the Hg(2+)-amen...
