“…Rios and Castaneda (2013) carried out a study to identify the best method of lipid extraction to undergo the potentiality of some micro-algal biomass obtained from two different harvesting path ways. One step lipid extraction-transesterification reached the same fatty acid methyl ester yield as the Bligh and Dyer and soxhlet extraction with n-hexane methods with the corresponding time, cost and solvent saving (Rí os et al, 2013). It was further reported that, one step transesterification (Direct Transesterification or in situ transesterification) reaction was effective compare to other conventional methods.…”

“…Biodiesel production from micro-algae and cyanobacteria involve different but directly related steps such as the sampling, cultivation, biomass harvesting, extraction and trans-esterification of lipids (Santos et al, 2014) and production, concentration, lipid extraction followed by transesterification (Rí os et al, 2013) or biomass harvesting, dewatering, pre-treatment, lipid extraction, lipid trans-methylation, anaerobic fermentation (Halim et al, 2013). The biodiesel production process along with steps involved in cultivation of cyanobacteria and microalgae can be summarized by biomass cultivation, harvesting, drying and lipid extraction followed by conversion of extracted lipids to biodiesel and finally purification of the produced biodiesel.…”

The experimental design and techniques for biofuel production from different feedstock varies depending on geographical region, water sources (fresh water, sea water, waste water or brackish water) and overall, available species variations. Also the sampling, culture conditions, isolation, purification of cultures, harvesting, fatty acid extraction followed by conversion of extracted lipids to biofuel followed different methods in different studies. Therefore, it is a demand to simplify the techniques, improve the methods, and develop the efficiencies with less laborious inputs but rapid and best outcomes. Biofuel production research should focus not only selecting suitable biomass or obtaining high yield of lipids but also look for economically feasible method along with sufficient and continuous supply of biomass. Considering these, cyanobacteria and microalgae creates a great potential for biofuel production. In this review, we focused on compiling different materials and methods used for different studies and their best outputs towards biofuel production from cyanobacteria and micro-algae.

The recent achievements in the field of CO 2 capture and biofuel production through microalgae are presented in this chapter. Specifically, after a brief analysis of the main biological, chemical, and physical phenomena involved in the photosynthetic conversion of CO 2 to biofuels, the current technologies for CO 2 capture, microalgae growth, biomass harvesting, and lipid extraction are critically assessed with a particular focus on the potential exploitation of recent research results at the industrial scale. Finally, future scientific and technological directions for the direct CO 2 capture from flue gases through microalgae are also proposed.

“…Most likely, this is due to the low polarity of n-hexane that allows the selective extraction of triglycerides leaving back the other components of the lipid fraction. (D. Ríos et al, 2013), If on one hand, the use of n-hexane as extraction solvent is advantageous from an environmental point of view, the lower extraction yields make more negative the economics of the process. The use of moderate amounts of CM may be a more convenient solution if the solvent is recovered and recycled Among the used techniques; MW showed the best results in the shorter time of extraction (20 h vs 60 h for all the other methods).…”

In this paper we describe our approach to solve the problem of the simultaneous transesterification of lipids (that requires a basic catalyst) and esterification of FFAs (that requires an acid catalyst) using mixed oxides ad hoc prepared. New mixed oxides based on calcium, cerium and aluminium have been used as catalysts in the reaction of trans-esterification of oils of different composition and quality, namely: i) extra virgin olive oil as a test case (low acidity) and ii) non-edible oil (high acidity), such as that extracted from aquatic biomass (Nannochloropsis sp microalgae). Among the several catalysts used, 12CaO 7Al2O3 7CeO2 has shown unprecedented properties in terms of activity and resistance in the simultaneous transesterification/esterification.
