چکیده انگلیسی
Microalgae Chlorella minutissima 26a was cultivated in a tube-cylinder internal-loop airlift photobioreactor under continuous cultivation conditions. The goal was to investigate the influence of different nitrate levels on the growth and composition of microalgae. Three nitrate concentrations (75, 150 and 225â¯mgâ¯Lâ1) were assessed under a fixed flow rate and the outlet flow was analyzed for concentration of biomass, lipid, carbohydrate and protein. Nitrate concentration at higher level (225â¯mgâ¯Lâ1) in the medium promoted biomass growth (188.6â¯mgâ¯Lâ1â¯dâ1) and lipid production (92.8â¯mgâ¯Lâ1â¯dâ1), and decreased carbohydrate amount (29.1â¯mgâ¯Lâ1â¯dâ1) without any change in protein content (37.7â¯mgâ¯Lâ1â¯dâ1). Use of tube-cylinder internal-loop airlift photobioreactor in continuous mode could be a promising approach in algal biorefineries so called 3G biorefineries, resulting in high biomass productivity in a simple cultivation system.
