Study of the Fate of Lipophilic Wood Extractives During Acid Sulphite Pulping Process by Ultrasonic Solid-Liquid Extraction and Gas Chromatography Mass Spectrometry

Extraction Procedures and GCxGC-TOFMS Determination of Fatty Acids (FAs) in Cyanobacteria Cultures and the Effect of Growth Media Iron Concentration Variation on Cellular FAs Composition

“…However, due to the nature of algae biomass, and the fact that they contain unusual lipid classes and fatty acids which differ from the ones in higher animals and plants [7], it is important to investigate a suitable extraction method for lipids and fatty acids from algae biomass. Among the techniques which are reported to be suitable, ultrasonic solid liquid extraction techniques has been found to be more effective as well as time effective [11]. Lipids and fatty acids in particular can be effectively extracted using polar organic solvents which are able to extract a larger range of organic compounds from biomass samples mostly at an elevated temperature [12].…”

“…Lipids and fatty acids in particular can be effectively extracted using polar organic solvents which are able to extract a larger range of organic compounds from biomass samples mostly at an elevated temperature [12]. This is attributed to the fact that at higher temperature the polar solvent decreases its polarity to allow it to capture compounds ranging from semi-polar to non-polar [11,13,14].The mixture of chloroform and methanol has been reported to be the most effective solvent composition for extraction of lipids from cyanobacteria biomass. However, due to the environmental issues the newly emerging ionic liquids have been utilized in the extraction and analyses of different organic compounds from different matrices [15][16][17][18].…”
