“…The most nutritive medium, BBM, was more favorable for FAME accumulation. However, media with less nitrogen may favor the increase of FAME as observed by Menezes et al (2016).…”

“…The semi-continuous system is a good alternative to cultivate A. obliquus and under optimized conditions can produce 586 mg L -1 day -1 of dry biomass and 48% of lipid content (Feng et al 2014), which is satisfactory for biodiesel production. Thus, adopting an estimate for the production of biomass in semi-continuous system with daily removal of 25% of the volume of A. obliquus on the seventh day of cultivation (Lourenço 2006) and considering a raceway with 3 million liters (1 hectare or 10,000 m 2 with depth of 0.3 m) and 300 days of cultivation per year (Slade and Bauen 2013;Menezes et al 2016), A. obliquus used in this study can produce an average of 600.0 kg ha -1 day -1 or 180.00 t ha -1 year -1 of dry biomass in DAF medium; 691.5 kg ha -1 day -1 or 207.45 t ha -1 year -1 in the DAF ? OGR; and 689.25 kg ha -1 day -1 or 206.78 t ha -1 year -1 in the BBM.…”

“…This makes A. obliquus as promising as the main microalgae indicated for biodiesel production, such as Choricystis minor var. minor (Skuja) Fott, which has 10.3-11.7% of TUFA and 2.3-2.5% of PUFA (Menezes et al 2016).…”

Microalgae biodiesel production depends on several factors to minimize the costs of the production process from both biomass and biodiesel. In some outdoor systems, the temperature can be higher than 35°C, which is lethal for several algae. Prospecting microalga from thermal environments seems to be a good option. Therefore, the objective of this work was to isolate a microalga (Acutodesmus obliquus (Turpin) Hegewald and Hanagata) from thermal water and evaluate its cultivation productivity in Bold Basal Medium (BBM) and in lower cost alternative media. One alternative medium contained only the main growth ingredients (DAF), the other included these same ingredients with the addition of wastewater from the purification of grease-based raw materials (DAF ? OGR). Microalga biodiesel productivity was also compared with the biodiesel yield of soybean, which is one of the main raw materials currently used for biodiesel production. The microalga was shown to provide biomass with similar productivity using the three different culture media in log phase. The microalga exhibited biodiesel productivity from 46 to 61 times higher than soybean; using 5.5-7.2% of the water and 1.6-2.2% of the land required for soybean cultivation to produce the same amount of biodiesel. The DAF ? OGR medium, which costs 29% of the cost of the BBM medium, proved to be an efficient alternative medium compared to other in biomass productivity. Levels of tri-unsaturated and polyunsaturated fatty acids from A. obliquus microalga were slightly higher than those standardized by EN14214, requiring that the biodiesel be mixed with antioxidants.

“…Considering the environmental sustainability, like biodiesel production, taking account that European legislation (European Committee, 2008) establishes a maximum of 12% for linoleic acid and 1% for polyunsaturated acids (PUFA) (EN 14214). In addition to linolenic acid, γ-linolenic acid (C16:3 cis 6,9,12), C16:3 and C17:3 may also be present in microalgae species (Soares et al., 2013; Menezes et al., 2016). Since these are similar to linolenic acid, they need to be taken into consideration.…”

“…The gas chromatography coupled to flame ionization detector (GC-FID) is a powerful tool to detect and characterize FAME. These substances are thermally stable (Soares et al, 2013(Soares et al, , 2014 and it is the most applied method for the FAME analysis in vegetables, fruits, animal and microorganisms (Cossignani et al, 2011;Menezes et al, 2016;Blasi et al, 2017;Gouveia et al, 2017).…”

Considering the nutraceutical properties, the high commercial value from pigments and essential lipids and the environmental sustainability, the purposes of this study were to assess the major carotenoids and fatty acids composition of nine microalgae species as a source of nutraceutical compounds and as fatty raw material for biodiesel production. The carotenoid and fatty acid content were analyzed by high performance liquid chromatography tandem mass spectrometry detection method with atmospheric pressure chemical ionization mode (HPLC/APCI-MS/MS) and by high resolution gas chromatography with flame ionization detector (GC-FID). For the carotenoid analysis, the developed method presented a rapid response, a good chromatographic separation, higher sensitivity and can provides more compounds information due the mass spectrum. Among the microalgae evaluated, Desmodesmus protuberans (10.3 mg g -1 ), Desmodesmus denticulatus var. linearis (8.43 mg g -1 ) and Chlamydomonas planctogloea (7.4 mg g -1 ) are good lutein sources. Coelastrum sphaericum (15.29 mg g -1 ) and Parachlorella kessleri (22.96 mg g -1 ) showed high astaxanthin content; the others microalgae species presents low carotenoid content. In addition, Chlorella zofingiensis provides high quantities of γ-linolenic acid (4.3%). Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) levels were lower than 1.1 %. Regarding for biodiesel production, the promising strains are Coelastrum sphaericum and Parachlorella kessleri .
