Abstract
Microalgae oils have emerged as potential sources of nutrition, energy and oil besides useful bi-products, such as nutraceuticals, antioxidants and high performance lubricant additives. Microalgae are unicellular photosynthetic organisms with 5-50 µm in size that require primarily three components to produce biomass, i.e., water, CO2 and sunlight with relatively higher photosynthetic efficiency against terrestrial plants. Microalgae biomass is comprised of neutral (tri acyl glycerides, TAG; free fatty acids, FFA) and polar lipids (glyceroglyco/phospholipids) besides specific molecules with high industrial potentials. Neutral lipids are imortant feedstocks of biodiesel due to their similarity with regular vegetable crops with regard to saturated and unsaturated fatty acid profile (C14 to C22) including C20:3, C20:5 (EPA) and C22:6 (DHA). The presentation will highlight the role of Mass spectrometric techniques (ESI-MS;TOF, QMS; GC-MS) for determination of composition of microalgae oils generated from biomasses of Dunalialla salina, Chlorella vulgaris, Spirulina platensis and Scemedesmus oblique species cultivated on a lab scales under different growth parameters in fresh and industrial waste water with an emphasis on exploring the biodiesel and PUFAs potential.
