Chlorella, deriving its name from the Greek, “chloros” meaning green and “ella” meaning small, is a green algae that grows in fresh water. Chlorella emerged over 2 billion years ago, and was the first form of a plant with a well-defined nucleus.
Each chlorella microorganism is composed of a nucleus, starch grains, chloroplasts and mitochondria surrounded by a cell wall composed mainly of cellulose.
Under the proper growing conditions, Chlorella yields oils high in polyunsaturated fats. In fact, Chlorella minutissima has yielded EPA at 39.9% of total lipids.
