Dunaliella salina is a green marine flagellate whose main storage product is glycerol. Its ability to grow in waters which vary greatly in salinity is due to its ability to form glycerol, the intracellular concentration of which is directly proportional to the extracellular salinity. Copper is an essential trace element needed in small quantities by algae for plastocyanin production. However, at high concentrations it acts as an effective algicide. Dunaliella species have been shown to have an unusual resistance to copper toxicity. The authors examined the effects of lethal and sublethal concentrations of copper on growth and glycerol production in dunaliella saline, in order to determine if adaptation to copper toxicity will result in an increase in production of glycerol.
