“…are considered as first generation biodiesel feedstocks for biodiesel production. However, use of these feedstocks has faced problems as they disturb the overall worldwide balance of food reserves and safety (1). 98 The second generation of biofuels crops comprises lignocellulose biomasses such as cereal straw, sugar cane bagasse, forest residues; and organic components of municipal solid wastes (2).…”

Fourier transform infrared (FTIR) spectroscopy was used in this study to identify and determine spectral features of Chromochloris zofingiensis (Dönz) Fucíková et L.A.Lewis Gottingen, Germany), Acutodesmus obliguus (Turpin) Hegewald Gottingen, Germany) and Chlorella sorokiniana (K. Brandt) Pröschold et Gottingen, Germany). Polysaccharides and lipids from these three algae species were determined using Fourier Transformed Infrared Spectroscopy (FTIR) with ATR accessory with diamante crystal in spectral range from 400 -4000 cm -1 and resolution 4.

Microalgae are an indispensable food source for the various growth stages of mollusks, crustaceans, and several fish species. Using a microalgae biomass present in the Amazonian ecosystem (Macapá-AP), we study extraction methods for fatty acid such as solvent extraction (magnetic stirring and/or Soxhlet) and/or hydrolysis (acid and/or enzymatic catalysis) followed by esterification and/or direct transesterification. Extraction of crude triacylglycerides by mechanical stirring at room temperature was more efficient than continuous reflux (Soxhlet). Subsequently, the lipid extract was subject to transesterification with ethanol and CAL-B as a biocatalyst, leading to production of fatty acid ethyl esters (FAEE). Additionally, FAEEs were prepared by hydrolysis of crude triacylglycerides followed by acid-mediated esterification or enzymatic catalysis (lipase). In this case, the type of catalyst did not significantly influence FAEE yields. In the lipid extract, we identified palmitic, linoleic, oleic, and stearic acids with palmitic acid being the most abundant. Our results suggest that enzymatic catalysis is a viable method for the extraction of lipids in the microalga, Scenedesmus ecornis.

“…Furthermore, biofuels contribute in reducing the dependency on conventional fuel sources in many countries [4] and they are equally considered to represent and compromise between meeting energy needs without causing further environmental damage [2]. Biodiesel is attracting interest due to several reasons, some of which are the following [5]- [7]: i) it is biodegradable and has no toxicity characteristics, ii) it has a lower contribution to air emissions, iii) it can be produced from renewable precursors, iv) it has negligible sulfur content, superior flash point and higher combustion efficiency v) and it can be used in vehicles without modifying the engine due to the fact that biodiesel has the same physical and chemical characteristics as diesel. Biodiesel can be produced via a variety of feedstocks, which are classified according to availability of use for other purposes.…”

“…Biodiesel can be produced via a variety of feedstocks, which are classified according to availability of use for other purposes. First generation feedstock (palm, rapeseed, soybean, coconut) have edible oils that are suitable for human consumption, second generation feedstock consists of oils that are inappropriate for human consumption (jatropha, karanja, jojoba, mahua, waste cooking oil, grease, animal fats), and finally third generation feedstock is defined as new products obtained from biological reactions/processes, such as microalgae [7]. Currently, the two most common feedstocks which are being used for producing biodiesel are rapeseed (in Europe) and soybean (in the United States).…”

Abstract-The aim of this work was to perform life cycle analyses (LCA) based on detailed process mass and energy balances for the production of biodiesel from microalgae in order to compare the conventional transesterification with in situ transesterification. GaBi software was used to perform the LCA. The material balances revealed that a slightly lower biodiesel yield was obtained for in situ transesterification process (5.06 kg/day) when compared to the conventional one (5.5 kg/day). GaBi results showed that the global warming potential (GWP) of the conventional transesterification process was higher than in situ transesterification by 140 kg CO 2 equivalent (per tonne of biodiesel produced). No substantial difference was noted however, for acidification (4.15 vs. 4.34 kg SO 2 equivalent), eutrophication (0.641 to 0.666 kg PO4-equivalent) and human toxicity potential (72.3 vs. 77 kg dichlorobenzene equivalent) between the two processes per kg of biodiesel produced. The results of the LCA analysis also show that electricity production was the major contributor for all the environmental impacts. When both the global warming potential and biodiesel yield were taken into account, it could be concluded that biodiesel production via in situ transesterification was a better option.
