通过摇瓶培养考察转小鼠金属硫蛋白基因集胞藻6803(转基因藻)及其野生藻(集胞藻6803)的光合自养培养过程中碳源(碳酸钠)浓度、氮源(硝酸钠)浓度和光照度对这两种藻生长的影响。野生藻的最适生长碳源浓度(0.05~0.1g/L)比转基因藻的最适生长碳源浓度(0.02~0.05g/L)高。氮源浓度对转基因藻和野生藻的影响趋势相同。在0.3~4.5g/L范围内,随着氮源浓度的增高,藻体生长的最大细胞浓度降低。转基因藻生长的最佳光照度为1 500lx,野生藻生长的最佳光照度为3 000lx
The concentrations of carbon source (sodium carbonate), nitrogen source (sodium nitrate, sodium nitrite, sodium nitrite, sodium nitrite, ) Concentration and light intensity on the growth of these two species of algae. The optimum growth carbon concentration (0.05-0.1 g / L) of wild algae was higher than that of transgenic algae (0.02-0.05 g / L). The effect of nitrogen concentration on transgenic algae and wild algae trends the same. In the range of 0.3 ~ 4.5g / L, the maximum cell concentration of algal growth decreased with the increase of nitrogen source concentration. The optimal illumination of transgenic algae was 1 500lx and that of wild algae was 3 000lx
