Microalgal pigments potential as byproducts in lipid production

Microalgal biofuel revisited: An informatics-based analysis of developments to date and future prospects

“…These analyses revealed that research in microalgal biofuel occurred more rapidly and entered the burst stage relatively earlier than research in the other two areas, which gradually entered the period of rapid development. Because the greatest challenge for the manufacturing and application of algae-based biodiesel is the high cost of cultivation, harvesting, and biofuel extraction and production [41,69], research into microalgal mass culturing and microalgal biotechnology for the production of high value-added products and environmental applications has been greatly promoted in an attempt to make the entire process economically feasible for industrialization. However, the unacceptably high cost of microalgal biofuel production will continue to be a bottleneck for the development of further methods [70], and has resulted in a recent sharp decrease in research on microalgal biofuel and a further reduction in investment in the other two research directions and even in overall microalgal research.…”

“…3D). Because the high price of algae-based biofuel hampers its large-scale manufacturing [41,69], studies that focus on using oil-producing microalgal biotechnology to make microalgal biofuel production economically viable have been encouraged.…”

Production of Biodiesel From Microalgae.

“…Photobioreactors are continuous culture systems which can achieve concentration of microalgae up to 6.7 g/L (Bai et al, 2011;Chisti, 2007;Ranjbar et al, 2008) in fresh or sea water. Different models of photobioreactors (indoor or outdoor) have been developed including tubular, flate plate, airlift, bubble column and stirred tank (L. Xu et al, 2009).…”

“…The nature of lipids is an important data for biodiesel production because some microalgae can contain up to 93% (g /g lipid) of phospholipids and glycolipids (Williams & Laurens, 2010). Moreover, some microalgae can also contain lipids such as unsaponifiable lipids carotenoids and other elements (chlorophyll) which are considered as by-products (Bai et al, 2011).…”

Low Cost Alternative Fuel from Biomass

“…4(b), indicated that the interaction between the reaction duration and amount of crude oil to methanol ratio is dominated by reaction duration. It could be interpreted that, at higher reaction temperatures, there is a chance of loss of methanol with longer reaction duration and basically the esterification reaction was kinetics limited so that the yield was faster initially but later the yield decreases due to reversible nature [22]. o C reaction temperature, crude oil to methanol ratio of 1:25 and catalyst weight 2gm, an optimum biodiesel yield of 60.095% was obtained.…”
