“…The continued use of petroleum sourced fuels is now widely recognized as unsustainable because of the depletion supplies and the contribution of these fuels to the accumulation of carbon dioxide in the environment leading to increase of global warming. In the last ten years, many studies have been conducted on biofuels for substituting fossil fuels and reduce the greenhouse gas emission (Bastianoni et al, 2008). Biodiesel from oil crops, waste cooking oil and animal fat cannot realistically satisfy even a small fraction of the existing demand for transport fuels.…”

RESUMENMejora de la producción de biodiesel a partir de diferentes especies de algas.Ocho especies de algas (4 Rhodo, 1 cloro y 1 macroalgas phaeophycean, 1 cianobacteria y 1 microalga verde) fueron utilizados para la producción de biodiesel utilizando dos sistemas de extracción con disolventes (hexano/éter (1:1, v/v)) y (Cloroformo / metanol (2:1, v/v)). La evaluación bioquímica de las especies de algas se llevó a cabo mediante la estimación de los porcentajes de biomasa, de lípidos, de biodiesel y de sedimento (glicerina y pigmentos). El sistema extracción con el disolvente hexano/éter (1:1, v/v) produjo una bajada de los porcentaje de lípidos (2.3-3.5% de peso seco), mientras que el sistema de extracción con el disolvente cloroformo/metanol (2:1, v/v) demostró ser más eficaz en la extracción de los lípi-dos y del biodiésel (2,5 -12,5% de peso seco) dependiendo de las especies de algas. Los extractos de microalgas verde Dictyochloropsis splendida produjeron los mayores porcentaje de lípidos y de biodiésel (12,5 y 8,75%, respectivamente), seguida de la cianobacteria Spirulina platensis (9,2 y 7,5% respectivamente). Por otra parte, las macroalgas (rojo, marrón y verde) produce los porcentajes más bajos de biodiesel (0,25 -3,8%). Los ácidos grasos del biodiesel de Dictyochloropsis splendida Geitler se determinaron mediante cromatografía de gases. La producción de lípidos, de glicerol y de biodiesel con microalga verde Dictyochloropsis splendida Geitler (el alga más prometedora) fueron notablemente mejorada cuando se aumentó la concentración de sal o en ausencia de nitrógeno, durante su cultivo, con una producción máxima (26,8, 18,9 y 7,9%, respectivamente) en ausencia de nitrógeno. PALABRAS CLAVE: Biodiesel -Glicerina -Macroalgas -Microalgas -Lípidos totales SUMMARY Enhancement of biodiesel production from different species of algae.Eight algal species (4 Rhodo, 1 chloro and 1 phaeophycean macroalgae, 1 cyanobacterium and 1 green microalga) were used for the production of biodiesel using two extraction solvent systems (Hexane/ether (1:1, v/v)) and (Chloroform/ methanol (2:1, v/v)). Biochemical evaluations of algal species were carried out by estimating biomass, lipid, biodiesel and sediment (glycerin and pigments) percentages. Hexane/ ether (1:1, v/v) extraction solvent system resulted in low lipid recoveries (2.3-3.5% dry weight) while; chloroform/methanol (2: 1, v/v) extraction solvent system was proved to be more efficient for lipid and biodiesel extraction (2.5 -12.5% dry weight) depending on algal species. The green microalga Dictyochloropsis splendida extract produced the highest lipid and biodiesel yield (12.5 and 8.75% respectively) followed by the cyanobacterium Spirulina platensis (9.2 and 7.5 % respectively). On the other hand, the macroalgae (red, brown and green) produced the lowest biodiesel yield. The fatty acids of Dictyochloropsis splendida Geitler biodiesel were determined using gas liquid chromatography. Lipids, biodiesel and glycerol production of Dictyochloropsis splendida Geitler (the promis...

“…While microalgae have been the focus for biodiesel production due to their generally higher lipid content, there has been some work on bio-oil production from macroalgae, through either extraction or liquefaction technology (Aresta et al, 2005b;Bastianoni et al, 2008;Zhou et al, 2010).…”

“…Production of biofuels corresponds only to 1% of fuel requirements at the present day; it is expected to reach 7% in 2030 passing from a first generation of today to the carbon negative biofuels of 2030 [46]. The question of sustainability of biofuels is of great interest indeed to the present reasoning too, thus stressing on the importance of LCA concern for comparing biofuels ( [28], [33], [44], [47][48][49][50]). Also blending strategies of pure oils with liquid hydrocarbon fuels seems to be an effective strategy to pursue [51].…”

The pollution caused by fuel combustion either for mechanical or electrical energy generation purposes is nowadays one of the most important environmental issues. It has been proven that combustion emissions, particularly those from cars and trucks, are linked with severe damages to the environment and human health. Along with the environmental problems, is necessary to consider that fossil resources are declining and their exploitation is getting more and more expensive. Bioenergy represent a sustainable solution for energy generation. Bioenergy is renewable energy made from plant-derived organic matter, collectively termed "biomass". Biomass-based energy sources are potentially carbon dioxide neutral and recycle the same carbon atoms. Life cycle assessments are reported to evaluate the net environmental impacts of biofuels. The term biofuel refers to liquid or gaseous fuels for the internal combustion engines that are predominantly produced from biomass. Biofuel policy might capitalize on the production of biofuels supporting rural economic development and sustainable agriculture. Amongst biofuels pure plant oil (PPO) has been investigated. This paper sets out to review the state of the art for PPO use as fuel in diesel engines, based on a wide literature review.
