The microalgae
Neochloris wimmeri,
Scenedesmus vacuolatus,
Scotiellopsisoocystiformis,
Chlorella zofingiensis and
Protosiphon botryoides were grown under secondarycarotenoid inductive conditions. The results indicatethat nitrogen deficiency and high light intensity arepotential inducers of astaxanthin formation in thefive microalgae studied. All these microalgaeaccumulate significant quantities of secondarycarotenoids, mainly as astaxanthin esters andcanthaxanthin. They also showed high resistance toenvironmental conditions. All these qualities makethese microalgae good candidates for successfulculture in open ponds.
