To comprehensively understand kinetic characteristics of microalgae growth and lipid synthesis in different phases, a phase-feeding strategy was proposed to simultaneously regulate light, carbon and nutrients in adaption, growth and stationary phases of microalgae cultivation. Physiological-phased kinetic characteristics of microalgae Chlorella vulgaris growth and lipid synthesis under synergistic effects of light, carbon and nutrients were investigated, and supply-demand relationships of electrons and energy between light and dark reactions of photosynthesis process were discussed. Finally, the optimized cultivation strategy for microalgae in various phases were obtained, under which the lipid productivity was significantly improved from 130.11 mg/L/d to 163.42 mg/L/d. The study provided some important guidance for the large-scale production of biofuels from microalgae.
为了全面了解微藻在不同阶段的生长和脂质合成的动力学特性，提出了一种阶段喂养策略，以同时调节适应、生长和静止阶段微藻培养中的光、碳和营养物质。研究了协同光照、碳和营养物质对普通小球藻生长和脂质合成的生理阶段动力学特性，并讨论了光合作用过程中光反应和暗反应之间电子和能量的供需关系。最后，获得了微藻在各个阶段的优化培养策略，使脂质生产力从 130.11mg/L/d 显著提高到 163.42mg/L/d。该研究为大规模生产微藻生物燃料提供了一些重要的指导。
