The method comprises: inoculating a Yarrowia lipolytica strain into a seed culture medium for seed culture to obtain a seed liquid; and inoculating the seed liquid into a fermentation culture medium for high-density fermentation, and supplementing same with acetic acid and a nitrogen source during the process of high-density fermentation to obtain the single-cell protein, wherein the carbon source of the seed culture medium comprises a first acetate, and the carbon source of the fermentation culture medium comprises a second acetate and/or a ketone compound. In the present application, the compounding of specific materials and processes effectively increases the growth rate of bacteria and the synthesis rate of single-cell proteins, so that the method can realize the high-density fermentation of bacteria and efficient synthesis of single-cell proteins in a short time, a fermentation product with a higher content of crude proteins can be obtained while the culture time of high-density fermentation is significantly shortened, and the production efficiency and yield of single-cell proteins are greatly improved.
