In addition, potentials of microalgae proteins for farm animal nutrition have also been evaluated. Ju, Deng, and Dominy (2012) demonstrated that defatted microalgae could be used as a supplement for shrimp farm, and shrimps fedwith microalgae protein were healthier than that of control diet fed group.
Further, the research findings indicated that microalgae left over that is generated as a waste material of biofuel industries are a cheap source of bioactive proteins.
Gerde et al. (2013) revealed that 56.9% protein could be extracted from Nannochloropsis, a microalgae used for biofuel extraction, when using isopropanol defatted biomass.
Further, use of the waste for extraction of bioactive proteins would be a practicalway of recovering high cost associated with microalgae culturing.
