✦ Synopsis
The growth and biochemical composition of Scenedesmus bij~tgutits grown in normal and nutrient enriched Narendra Pond water was evaluated at different levels of salinity. In normal pond water (NPW) the growth was enhanced when the initial salinity of the water was doubled (to 7.2 mmol/l) but further salinity increase caused growth retardation. In nutrient enriched pond water (NEW), however, the maximum growth occurred in the culture containing 29 mmol/l of NaC1. At growth retarding salt concentrations the chlorophyll, carbohydrate, protein and lipid contents per cell decreased in both NPW and NEW while the proline content first increased and was then reduced. All nutrients, taken separately or in combination, caused growth enhancement of the alga at the three selected salinity levels. The alga showed a better halotolerance when enriched with nitrogen or phosphorus.
