Nitrogen (N) limitation is the most common strategy used to accumulate energy-rich compounds in microalgae. However, this condition reduces the microalga growth rate and biomass, lipid and carbohydrate productivities. In this work, a semi-continuous operation strategy combined with N feast–famine cycles were investigated in order to increase the lipid, carbohydrate and biomass contents in the microalga Scenedesmus obtusiusculus AT-UAM.

氮肥饥荒循环和半连续栽培对钝角栅藻AT-UAM高能化合物生产力的影响

氮 (N) 限制是用于在微藻中积累富含能量的化合物的最常见策略。然而，这种情况会降低微藻的生长速度和生物量、脂质和碳水化合物的生产力。在这项工作中，研究了一种半连续运行策略，结合 N 个饥荒周期，以增加微藻钝角栅藻AT-UAM 中的脂质、碳水化合物和生物量含量。
