Comparison of various microalgae liquid biofuel production pathways based on energetic, economic and environmental criteria

High temperature enhances lipid accumulation in nitrogen-deprived Scenedesmus obtusus XJ-15

“…The largest constraint is the acquisition of microalgal biomass with high lipid content. Thus, a number of recent studies have focused on maximizing lipid content to reduce costs (Mandal and Mallick 2009;Rodolfi et al 2009;Delrue et al 2013;Gardner et al 2013;Mus et al 2013;Münkel et al 2013).…”

Optimizing light regimes on growth and lipid accumulation in Ankistrodesmus fusiformis H1 for biodiesel production

“…However, the development and application of microalgae for biodiesel production is still in its infancy. At present, how to maximize lipid yield, reduce the cost and increase manipulation flexibility dealing with the various technology bottlenecks of the lipid production process in microalgae cultivation are the important tasks (Delrue et al, 2013;Bellou et al, 2014;He et al, 2015a). Nutrient (especially nitrogen) and light regimes (i.e., incolumn density, photoperiod and light intensity) are the major environmental determinants of microalgae growth, metabolism and morphology, including the accumulation of lipids in the form of triacylglycerols (TAG) (Eberhard et al, 2008;Damiani et al, 2010;Wahidin et al, 2013;He et al, 2015a,b).…”

Microalgal Biomass as a Source of Renewable Energy

“…The biomass is then anaerobically fermented in the digester producing liquid and biogas. The biogas is burnt and the liquid digestate is then recycled so that the nutrients can be reused (Delruea et al 2013 ).…”
