Abstract
According to the invention, it has been found that when the amount of sulfate used in the culturing of PUFAs-producing cells is selected such that the sulfate concentration drops to zero in the last phase of the growth phase of the cells, an easily disruptable biomass is obtained which has an increased proportion by mass of polyunsaturated fatty acids (PUFAs) in the final product.
