High Lipid Induction in Microalgae for Biodiesel Production
Sharma, Kalpesh K.; Schuhmann, Holger; Schenk, Peer M. - In: Energies 5 (2012) 5, pp. 1532-1553
Oil-accumulating microalgae have the potential to enable large-scale biodiesel production without competing for arable land or biodiverse natural landscapes. High lipid productivity of dominant, fast-growing algae is a major prerequisite for commercial production of microalgal oil-derived...
