Abstract: The objective of this study is to evaluate the growth of micro algae Chlorella protothecoides in various percentage of waste water sampled from different terminals in batch culture. Evaluation of the growth of the micro algae along with the lipid production is estimated. Parameters such as in chemical oxygen demand, growth curve of the algae and variation in elements nitrogen and phosphorous is investigated by the growth of the algae in waste water. The media used is the basal media for the cultivation of the algae. Waste water from the domestic treatment plant in the campus is obtained from the terminals grid chamber (1), aeration tank (2) and from the secondary clarifier(3). The maximum growth is observed to be in the 50% waste water sampled from secondary clarifier with the biomass of 1.008g/l. It is also seen that there is efficient reduction in COD, nitrogen and phosphorous leading to the treatment of waste water along with the secretion of lipid of 19%. Hence the cultivation of Chlorella protothecoides can be adopted to grow in the waste water rich in nutrients that becomes economical as it do not require any fertilizers, media or fresh waters in specific for the bio diesel production without affecting the food chain of humans nor having any impact on the environment.
