“…Microalgae, the largest biomass producers, have a high neutral lipid content, outcompeting terrestrial plants for biofuel production, and also have the ability to grow rapidly and synthesize and accumulate large amounts of neutral lipid stored in cytosolic lipid bodies (Mutanda et al, 2011). Biodiesel is produced from microalgal oil, thus crude fossil petroleum could be replaced by mass cultured biomass microalgal oil for eco-sustainable biodiesel production in the near future (Rawat et al, 2013). However, the high cost of algae production is the biggest obstacle to the adoption of an industrial and commercial process.…”

“…This type of biorefinery, which produces a variety of products from a single biomass source, may be termed a vertical biorefinery (Milledge 2013b). Although biorefineries could improve the economics of biofuel production (Pires et al 2012) they are likely to be energy intensive (Rawat et al 2013;Olguin 2012), and will involve increased energy inputs, process complexity and possibly reduced energy outputs. A biorefinery plant should operate sustainably with its energy met by biofuels produced (Cherubini 2010).…”

“…The chemical composition of such compounds encompasses starches and highly saturated fatty acids convertible to neutral lipids, which play an important role in production of bioethanol and biodiesel. This feature, along with high growth rates and ease of cultivation, make microalgae very promising when compared to higher plants (Rawat et al, 2013;Khan;Bahadar, 2013;Silva and Bertucco, 2016).…”

-Microalgae are considered as promising feedstocks for the third generation of biofuels. They are autotrophic organisms with high growth rate and can stock an enormous quantity of lipids (about 20 -40% of their dried cellular weight). This work was aimed at studying the cultivation of Scenedesmus obliquus in a two-stage system composed of a photobioreactor and a settler to concentrate and partially recycle the biomass as a way to enhance the microalgae cellular productivity. It was attempted to specify by simulation and experimental data a relationship between the recycling rate, kinetic parameters of microalgal growth and photobioreactor operating conditions. Scenedesmus obliquus cells were cultivated in a lab-scale flat-plate reactor, homogenized by aeration, and running in continuous flow with a residence time of 1.66 day. Experimental data for the microalgal growth were used in a semi-empirical simulation model. The best results were obtained for 0.2, when R = 1 and k d = 0 and 0.05 day -1 , with the biomass production in the reactor varying between 8 g L -1 and 14 g L -1 , respectively. The mathematical model fitted to the microalgal growth experimental data was appropriate for predicting the efficiency of the reactor in producing Scenedesmus obliquus cells, establishing a relation between cellular productivity and the minimum recycling rate that must be used in the system.
