    Abstract: Novel closed system methods and apparatus for the production and utilization of algae are disclosed. A substantially pure form of a desired strain of alga is obtained and cultivated (or isolated and grown). The desired species of alga is isolated from the contaminants and other algae and placed in the controlled environment where its growth is cultivated without contaminants. At desired points in time, a portion of the cultivated alga is removed, with the remainder serving as progenitor stock for growing more of the desired alga. The removed alga is processed and placed in product form.
