In PUFAs w-3, docosahexaenoic acid (DHA) is absolutely necessary for normal development of the fetus and baby. DHA has some positive effects on human diseases such as hypertension, arthritis, arteriosclerosis, depression and thrombosis…. Therefore, DHA has contributed to many kind of worth product such as milk for pregnant woman and baby, drugs and functional food for human and animals.<strong> </strong>In this paper, for the first time, we succeeded in isolating of <em>Schizochytrium</em> sp. PQ6 and PQ7 - a new heterotrophic marine microalga, from Phu Quoc district coasts. The growth rate, dry weight, concentration of total lipid and the component of PUFAs in M1 media were analyzed in both strains. The DHA content of strains<em> Schizochytrium </em>sp. PQ6 and PQ7 are about 1.57 and 1.48 g/l, respectively. In comparison with other current marine microalgae in Vietnam, <em>Schizochytrium</em> sp. PQ6 and PQ7 have the highest concentration of PUFAs, especially content of DHA. That gives us new prospect for using these <em>Schizochytrium</em> as animal feed (e.g. for rotifer, krills, shrimp’s larvae, etc.) and functional food for human.</p>}, number={2}, journal={Academia Journal of Biology}, author={Hong, Dang Diem and Anh, Hoang Lan and Hoai Thu, Ngo Thi}, year={2014}, month={Nov.}, pages={50–55} }
