CG (Crude glycerol) is one of the major wastes of biodiesel production process. It can be used as a substrate for lipid production by algae and the produced lipid can be recycled as a feedstock for biodiesel production. In order to avoid substrate inhibition, lipid production media are prepared by diluting the CG with distilled water. However, CG contains only a small amount of Mg (57.41 ± 18 ppm) and its concentration is further decreased to around 0.57 ppm during the dilution process. Apart from having a number of roles in algal physiology, Mg is the central atom of chlorophyll. Therefore, MgSO₄ was evaluated as a Mg source to supplement the CG based media used for lipid production by Chlorella vulgaris. By supplementing the process with 1 g/L of MgSO₄, nearly 185.29 ± 4.53% improvement in lipid production has been achieved. Further, application of MgSO₄ nanoparticles was found to improve the lipid production by 118.23 ± 5.67%. Interestingly, unlike MgSO₄, its nanoparticles were found to enhance the lipid production at the expense of only a small amount of glycerol. Thus, application of MgSO₄ nanoparticles could be a potential strategy for enhanced lipid yield.
