| 中文摘要: |
| 采用小球藻进行了静置培养和通气培养试验，研究了通气条件对小球藻生长速度、生物量、生物组成及脂肪酸组成的影响。结果表明：相对于静置培养（不通气），通气培养条件下，小球藻在稳定期的生长速度、生物量及其单位产量上高出10倍以上，差异极显著；小球藻的蛋白质含量、总糖含量明显较高，而总脂含量、淀粉含量则较低；小球藻饱和脂肪酸含量显著降低，不饱和脂肪酸特别是多不饱和脂肪酸含量升高。不同通气量对小球藻的生长也存在差异，其较适宜的通气条件为1 L/min。在小球藻的培养过程中，可通过适宜的通气措施来改善培养效果和获得较高的目标产物。 |
| 英文摘要: |
| Chlorella sp. was cultured under stationary condition and aeration condition respectively. The effects of aeration on the growth rate, biomass, biological component and fatty acid composition of Chlorella sp. were studied. The results showed that comparing with stationary cultivation, the growth rate, biomass and productivity of Chlorella sp. in stationary phase under aeration condition were ten times higher; the contents of protein and total sugar increased significantly, while the contents of total lipid and starch reduced; the saturated fatty acids became less, while unsaturated fatty acids, especially polyunsaturated fatty acids went up; different aerations had different effects on the growth of Chlorella sp., and the suitable aeration condition was 1 L/min. The proper aeration measure could be used to improve cultivation efficacy and obtain higher desired product during the cultivation of Chlorella sp.. |
