Photosynthetic microorganisms, in addition to the major planetary role in solar energy conversion and biogeochemical cycles, have a major contribution to a wide range of biotechnological applications. In this paper, we present our original results concerning the use of different concentrations of nitrate as stressor for enhancing the lipid content in our isolate, a green microalga named Rd. The effects on cellular growth, lipid, total protein, chlorophyll a and b, and carotenes content are also presented. The results are discussed with respect to applicative and basic research approaches for a deeper understanding of the mechanisms involved in the response of microorganisms to stress.
