Abstract: Abstract: The growth rates, lipid characteristics, and fuel properties of fatty acid methyl esters (FAME) made from the microalgae cultured in deep sea water (DSW) were analyzed and compared with those made from the microalgae cultured in surface sea water (SSW). The mineral nutrients including nitrates, silicates, and phosphates contained in DSW were, respectively, 7.8, 4.6, and 5.2 times than those of the corresponding nutrients in SSW. The experimental results also show that the lipid content, growth rate, biomass formation, and production of fatty acid methyl ester (FAME) of the microalgae cultured in DSW were significantly greater than those of the microalgae cultured in SSW by 23.0%, 120.0%, 4.7%, and 9.5%, respectively. In addition, the microalgae cultured in DSW took additional 2 days to reach their maximum biomass quantity than those cultured in SSW. Biodiesel made from Chaetoceros muelleri grown in DSW had the highest content of saturated fatty acids and the lowest composition of mono-unsaturated fatty acids and iodine number among those three biodiesels studied here. DSW is thus a favorable medium for microalgae cultivation to generate lipid and biodiesel with adequate fuel properties.
