“…Other FAMEs present in substantial amounts ($15%) are palmitic acid methyl ester (C16:0), linolenic acid methyl ester (C18:3n3), and linoleic acid methyl ester (C18:2n6c). The fatty acids composition of lipids from C. vulgaris was studied by Petkov and Garcia [37] and their results are similar to ours. Small quantities of methyl esters from fatty acids with less than 15 carbons and more than 19 carbons were also observed in this study, and was confirmed by a previous study [38].…”

“…In addition, Bigogno et al (2002) demonstrated that, in the green oleaginous alga Parietochloris incisa, changes in growth phase and conditions that resulted in TAG increases also resulted in a simultaneous decrease in the proportions of MGDG, DGDG, SQDG and PL, which agrees with the changes in AMPL at the lowest N treatment and Cd stress in this study. Fatty acid production by C. vulgaris exhibited a high degree of plasticity with changing culture conditions, with most fatty acids having long chain length groups of 16 and 18 carbon atoms (Brett et al, 2006;Petkov & Garcia, 2007;Villar-Argaiz et al, 2009). Pinto et al (2011) showed that SAFA and MUFA content of Gracilaria tenuistipitata increased with increasing Cd concentration, which is in agreement with our study showing increased SAFA and MUFA production by C. vulgaris in the presence of Cd.…”

“…Algae synthesize fatty acids as building blocks for the formation of various types of lipids. The commonly synthesized fatty acids in green algae have chain lengths from C 16 to C 18 (Petkov & Garcia, 2007). Fatty acids are either saturated or unsaturated, and unsaturated fatty acids may vary in number and position of double bonds on the carbon chain backbone (Hu et al, 2008).…”

Investigations were carried out to evaluate lipid class and fatty acid composition of Chlorella vulgaris in relation to several combinations of cadmium (2 Â 10 -8 ; 10 À7 M Cd) and nitrogen (2.9 Â 10 À6 to 1.1 Â 10 À3 M N) concentrations. Triacylglycerols (TAG), acetone mobile polar lipids (AMPL) and phospholipids (PL) were the major lipid classes of C. vulgaris under all the tested conditions. TAG was the lipid class accumulated in the highest amount in N-limited C. vulgaris. The AMPL lipid class was lowest at the lowest N and highest Cd treatment. High proportions of saturated fatty acids (SAFA) and monounsaturated fatty acids (MUFA) in the total lipid extracts were recorded under N limitation in the presence of Cd. 16:1(n-11) was an exception among the MUFA as its levels decreased at low N. Total polyunsaturated FA (PUFA), !3 PUFA levels, and PUFA:SAFA ratios increased with increasing N concentrations, but when exposed to Cd, their levels were significantly reduced. Unlike the other PUFA, 18:2(n-6) increased with increasing N limitation. Significant negative relationships between TAG, MUFA and SAFA with N were recorded. Cd had a positive correlation with TAG, while N was with AMPL, PL and PUFA. In conclusion, a combination of N limitation and Cd stress significantly altered the lipid composition of C. vulgaris, and N limitation had the most significant overall effect on lipid class and fatty acid composition of the microalga.

“…Nonetheless Besides the differences in the total quantity (sum) of recognized fatty acids (from 25 wt % to 45 wt %) the comparison of the different algae showed great differences in the FA profiles. Nonetheless the qualitative composition of the fatty acids is according to the one usually found in the Chlorella strain [22]. Also for N. oculata [23] and A. platensis [24] the composition of fatty acids resembles the known composition.…”

Hydrothermal Disintegration and Extraction of Different Microalgae Species

2018

Abstract:For the disintegration and extraction of microalgae to produce lipids and biofuels, a novel processing technology was investigated. The utilization of a hydrothermal treatment was tested on four different microalgae species (Scenedesmus rubescens, Chlorella vulgaris, Nannochloropsis oculata and Arthorspira platensis (Spirulina)) to determine whether it has an advantage in comparison to other disintegration methods for lipid extraction. It was shown, that hydrothermal treatment is a reasonable opportunity to utilize microalgae without drying and increase the lipid yield of an algae extraction process. For three of the four microalgae species, the extraction yield with a prior hydrothermal treatment elevated the lipid yield up to six times in comparison to direct extraction. Only Scenedesmus rubescens showed a different behaviour. Reason can be found in the different cell wall of the species. The investigation of the differences in cell wall composition of the used species indicate that the existence of algaenan as a cell wall compound plays a major role in stability.
