Tetraedron minimum , First Reported Member of Hydrodictyaceae to Accumulate Secondary Carotenoids
We isolated a novel strain of the microalga Tetraedron minimum in Iceland from a terrestrial habitat. During long-term cultivation, a dish culture turned orange, indicating the presence of secondary pigments. Thus, we characterized T. minimum for growth and possible carotenoid production in differen...
