Fatty-acid algae, concentration

Concentration of polyunsaturated fatty acids in the thylakoids of blue-green algae and light-induced volatile hydrocarbon production by spheroplasts in the presence of 50 nM Cu(II)... [Pg.126]

Earlier studies on microalgae took place during 1978-1996 with projects funded by the National Renewable Energy Lab (NREL). The major conclusion of the study in a closeout report by NREL in 1998 showed that algae oil-derived biodiesel is, even with all the improvements, at least two times higher in cost than crude oil-derived diesel. Other results of the NREL report (Ref. 91, pp. 28-31) indicate that some species contain substantial amounts of unusual components not found in other plants such as C13-0, C14-1, C15-0, C16-1, and even some with methyl-branched fatty acid content in concentrations of 3-5% to as much as 15-20%. [Pg.135]

Spitulina has been used for human nutrition for many years due to its high protein content and other nutrition value. In particular, this alga contains linolenic acid, an essential fatty acid that cannot be synthesized by humans. Annual production of Spitulina has been estimated to be around 3000 tons (Table 2.8).The latest producer is DIG Corporation (formerly Dainip-pon Ink and Chemicals), which is also the world s first company to produce Spitulina at commercial scales (http //www.dlt-spl.co.jp/business/en/spirulina/).This company has two sites for Spitulina production. One is in Hainan (People s Republic of China) and another one, Earthrise Farms, in California (USA). Aimual production for these two plants is 450 and 350 tons/year, respertively. Other notable producers are Cyanotech in Hawaii (USA) and Myanmar Spirulina Factory in Yangon, Myanmar. Spitulina requires high pH and bicarbonate concentration for growth. This selective requirement makes its commercial produaion easier since other microalgal strains cannot tolerate such harsh environmental conditions. [Pg.75]
