The haptophytes, predominately marine phytoplankton, are recognized as a division divided into two classes, Pavlovophyceae and Prymnesiophyceae (Cavalier-Smith

2007) . The chloroplast pigments are similar to those of the heterokonts, and in both divisions, chloroplasts are derived from red algal symbionts (Anderson 2004). Several members of the class Prymnesiophyceae including the Prymnesium (Becker 1994), Isochrysis spp. (Chisti 2007), and the Coccolithophores are oleaginous algae. Pavlova and Isochrysis spp. are widely used in the aquaculture industry because of their favorable lipid content (Walker et al. 2005). While the Haptophyta and Heterokonts are predominantly marine organisms, there are a number of species in both groups that are found in freshwater systems. In addition, certain types of wastewater such as the effluent from food processing plants have a much higher salinity than domestic wastewater.
