摘要： The present invention provides a method of culturing an alga that enables practical realization of low-cost and space-saving production of biofuels and bioenergy by culturing the alga using a reaction tank equipped with a digestive solution tank comprising digestive solution containing high concentration of nutrient salts, a membrane with a pore size of 0.45 µm or less and a culture tank comprising culture solution and the alga, which comprises consuming the nutrient salts by the alga in the culture tank to maintain the difference in concentration the nutrient salts between the digestive solution tank and the culture tank and supplying the nutrient salts contained in the digestive solution through the membrane into the culture solution by the diffusion depending on the concentration difference as well as an alga culture system therefor.
