چکیده انگلیسی
Temperature and light intensity are important environmental factors influencing microalgae for biodiesel production. The aim of present work was to study the effects of temperature (15â¯Â°C, 25â¯Â°C, and 35â¯Â°C) and its combination with high light intensity (HL, 400â¯Î¼molâ¯photonâ¯mâ2â¯sâ1) on lipid production of Monoraphidium dybowskii Y2 which was isolated from desert. The results demonstrated that algal growth was only inhibited at 15â¯Â°C. Promoted lipid content and decreased Fv/Fm were observed in 15â¯Â°C and 35â¯Â°C. Cellular carbohydrate, protein conversion and membrane lipid (MGDG, DGDG and SQDG) remodeling contributes for lipid accumulation. Stress combined temperatures with HL are benefit for lipid production, especially desired neutral lipid productivity all exceed 40â¯mgâ¯Lâ1â¯dâ1. Fatty acids compositions of C16:0 and C18:1 were further promoted under 15â¯Â°C or 35â¯Â°C combined with HL. Thus, M. dybowskii Y2 will well-adapted to outdoors cultivation for biodiesel production.
