Nutritional mode influences lipid accumulation in microalgae with the function of carbon sequestration and nutrient supplementation

- Microalgae nutritional mode effects biomass growth and lipid productivity.
- Mixotrophic nutritional mode showed higher biomass growth.
- Nutrient limitation enhanced lipid productivity from growth phase to starvation phase.
- Microalgae diversity and fatty acid composition varied with the nutritional modes.
- Good carbon/nutrient removal was observed during growth phase.
