In this study, five Nannochloropsis sp. strains recently isolated from China’s coastal waters were evaluated for their biodiesel and poly-unsaturated fatty acids (PUFAs) production potential. The results shown, Nannochloropsis sp. 628 achieved the highest biomass accumulation of 7.05 ± 0.21 g L-1, and Nannochloropsis sp. 1049 was the most promising lipid producer, with lipid content of 61.16 ± 0.03% dry cell weight (DCW) and lipid productivity of 235.89 ± 7.58 mg L-1 d-1. For all the strains, neutral lipid was the predominant component of total lipid which counted for percentages ranging from 69.25 ± 1.06% to 87.31 ± 0.26% total lipid. The favorable fatty acids (FAs) of saturated FAs, monounsaturated FAs and C16-C18 components of total FAs of the strains were all preferable attained. Suitable biodiesel properties within the prescribed limits were also revealed. High production ability of PUFAs (89.27 ± 7.79 mg L-1 to 134.94 ± 9.84 mg L-1) meant PUFAs could be considered as co-products of microalgae biodiesel production. The present study shown the Nannochloropsis sp. strains could be consider as valuable feedstock candidates for biodiesel production.
