Many oleaginous microalgal strains synthesizing high levels of PuFAs have been described [4]. Perveen et al. [5] characterized a Thraustochytrid-like microorganism (termed Strain 12B) that exhibited DHA productivity of 2.8 g/L/d upon shake flask cultivation. The highest DHA productivity (3.7 g/L/d) reported to date was attained upon fermentation of Schizochytrium limacinum SR21 in a laboratory scale bioreactor [6]. Large-scale fermentation of microalgal strain has also been reported; Schizochy- trium sp. HX-308 yielded DHA productivity values of 2.7 and 2.9 g/L/d when grown in 50-L and 1500-L bio-reactor, respectively
