ABSTRACT

Microalgae feedstock is gaining attention in the present energy scenario due to its fast growth potential with very little land use coupled with high lipid, carbohydrate, protein, nucleic acid, and bioactive metabolite contents and capacity to reduce pollution levels by utilizing nutrients from wastewater and carbon dioxide from ue gases (Amaro et al. 2013; Nigam and Singh 2011; Singh and Olsen 2011; Singh et al. 2011a,b,c). All of these properties render microalgae an excellent source for biofuels such as biodiesel, bioethanol, biohydrogen, and biomethane, as well as a number of other valuable pharmaceutical and nutraceutical products (Rathore and Singh 2013; Singh and Gu 2010; Singh et al. 2012).
