Abstract

This study aimed to improve lutein production using a thermo-tolerant lutein-rich microalga Desmodesmus sp. F51. To achieve this goal, four fed-batch cultivation strategies were investigated for CO2 fixation and lutein production of Desmodesmus sp. F51. Among them, Fed-batch IV showed the best performance, giving the highest CO2 fixation rate and lutein productivity of 1582.4mg/L/d and 3.91mg/L/d, respectively. Both increasing the light intensity and limiting the nutrients led to a lower carotenoids content in the microalga, with a higher proportion of lutein and lower proportion of β-carotene being obtained in the carotenoids. The carotenoid present in the biomass was mainly lutein, accounting for 50-66% of total carotenoids. Repeated operations of the Fed-batch IV strategy could effectively improve CO2 fixation and lutein production of Desmodesmus sp. F51, giving the best results of 1826.0mg/L/d, and 4.61mg/L/d, respectively. This performance is better than most of the previously reported values.
