Glycerol is a by-product from the production of biodiesel fuel (BDF), which is released from triacylglycerol by an ester exchange reaction with methanol under alkaline conditions. Because there is a considerable increase in BDF production worldwide, surplus waste glycerol has become an important material for the production of chemicals and fuels (Habe et al. 2009b). 

In the case of SCO utilization for biodiesel production, research interest is focused only upon the process of de novo lipid accumulation. In this case, there is continuously increasing interest upon the potentiality of transforming abundant renewable materials (such as waste glycerol, flour-rich waste streams, and cellulose and hemicellulose hydrolysates) into SCO that will be further transformed into biodiesel. The process of ex novo lipid accumulation aims at adding value to low-cost fatty materials so that speciality high-value lipids (eg, cocoa-butter or other exotic fats substitutes) will be produced (Papanikolaou et al., 2001, 2003 Papanikolaou and Aggelis, 2003a,b, 2010).
