(一) Volumetric productivity of biomass
The highest volumetric productivity of 0.31 g/L/day was obtained with the feed concentration of 0.1 g/L sodium nitrace under the dilution rate of 0.04 1/hr in the continuous cultiration. The highest volumetric productivity of 0.19 g/L/day was obtained with the feed concentration of 0.2 g/L sodium nitrace under the dilution rate of 0.06 1/hr. The highest volumetric productivity for batch cultivations was obtained with the initial concentrations of 4.2 g/L sodium bicarbonate and 0.5g/L sodium nitrate.
(二) Lipid content
The highest lipid content of 19.9 % was obtained with the feed concentration of 0.8 g/L sodium nitrate dilation rate of 0.04 1/hr in the continuous cultration.The highest lipid content of 15 % was obtained with the feed concentration of 0.9 g/L sodium nitrate under the dilution of 0.06 1/hr. The highest lipid content for batch cultiration was obtained with the initial concentrations of 8.4 g/L sodium bicarbonate and 1.0 g/L sodium nitate.
