The invention relates to application of mannose in culturing microalgae to improve oil accumulation of the microalgae. The concentration of the mannose in a culture medium is not lower than 0.5 g/L. Specifically, the method comprises the following steps: inoculating a microalgae seed solution into a culture medium containing mannose for inducing grease accumulation culture; or firstly inoculating the microalgae seed solution into the culture medium for culture, and then adding mannose into the culture medium for continuous culture in the culture process, so that the accumulation of the microalgae grease is improved by utilizing the mannose. The invention reveals that the grease accumulation of the microalgae can be improved when the mannose is applied to microalgae culture for the first time, and the grease content of the microalgae under different environmental conditions and growth states can be simply, flexibly and quickly induced and improved by using the concentration of the mannose which is not lower than 0.5 g/L.

Systems and methods for growing microalgae, preferably Chlorella genus (Chlorella sp.), capable of metabolism of mixed nutrition. Microalgae grown in a system using the method can survive and grow in dark refrigeration, which enables the algae to be stored and transported for application as live cultures. Furthermore, the microalgae can grow in sufficient amounts for commercial sales for application as a biostimulant to crops.
