ABSTRACT
Dunaliella, in common with other microalgae, possesses a range of systems to satisfy cellular demands for nutrients. In this chapter, we summarise what is known about the mechanisms involved in the acquistition of the major macronutrients N, P, S and C. We describe how uptake of these elements is affected by environmental conditions and the interactions that occur between C acquisition and the availability of the other commonly limiting macronutrients.
