A number of ecotypes of plants and algae with increased tolerance to heavy metals have been isolated from sites that are polluted with metals leading to their application in bioremediation of contaminated ecosystems. Glutathione is a key component involved in development of resistance/tolerance. The present study was focused on identifying the inhibitory concentrations and effects of copper, nickel and zinc on the growth of Chlorella sp. and recovery of cells from metal toxicity in the presence of reduced glutathione (GSH). The observations made during the study showed that toxicity of copper, nickel and zinc is ameliorated in the presence of GSH. GSH was also observed to indirectly facilitate the recovery of functional viability (as indicated by chlorophyll content) of the cells.
