| 英文摘要 | To improve biomass and microalgal oil production of Botryococcus braunii, fed-batch culture was investigated in an airlift photobioreactor. The optimal feeding time of the fed-batch culture was after 15 days of cultivation, where 1.82?g/L of the microalgal biomass was obtained in the batch culture. Nitrate nutrient was the restrictive factor for the fed-batch cultivation while phosphate nutrient with high concentration did not affect the microalgal growth. The optimal mole ratio of nitrate to phosphate was 34.7:1, where nitrate concentration reached the initial level and phosphate concentration was one quarter of its initial level. With one feeding, the biomass of B. braunii reached 2.56?g/L after 18 days. Two feedings in 2-day interval enhanced the biomass production up to 2.87?g/L after 19 days of cultivation. The hydrocarbon content in dry biomass of B. braunii kept at high level of 64.3% w/w. Compared with the batch culture, biomass production and hydrocarbon productivity of B. braunii were greatly improved by the strategic fed-batch cultivation. |
