چکیده انگلیسی
Scenedesmus obtusiusculus AT-UAM, isolated from Cuatro Ciénegas wetlands in Mexico was taxonomically, molecularly and biochemically compared to S. obtusiusculus CCAP 276/25 (Culture Collection of Algae and Protozoa, Scotland, UK). Analysis of Internal Transcribed Spacer 2 (ITS2) secondary structures confirmed that the mexican strain belongs to S. obtusiusculus with one change in the ITS2 nucleotide sequence. However, both strains exhibited different biochemical and fatty acid profiles and therefore biotechnological potential, emphasizing the need for deeper studies among strains of the same species. Furthermore, the biochemical variations of S. obtusiusculus AT-UAM under nitrogen starvation and different levels of irradiance were evaluated. The maximum lipid production (1730â¯mgâ¯Lâ1) was obtained at 613â¯Î¼molâ¯mâ2â¯sâ1 while the highest carbohydrate content (49%) was achieved at 896â¯Î¼molâ¯mâ2â¯sâ1. Additionally, this strain was capable of storing lipids (â¼52%) and carbohydrates (â¼40%) under outdoor condition depending on the light availability in the cultivation broth.
