小球藻产油脂培养条件的优化

Optimization of Culture Conditions on Lipid Production of Chlorella

为了更好的开发利用小球藻,探讨了光照强度、pH值及氮盐、磷盐、铁盐质量浓度等因素对小球藻油脂产量的影响,并采用单因素和正交试验对小球藻的培养条件进行优化。结果表明,小球藻的最佳培养条件为光照5 000lx、pH值6、氮盐质量浓度100mg/L、磷盐质量浓度160mg/L、铁盐质量浓度100mg/L,在此条件下,小球藻油脂产量最大,为615.12mg/L。

To better exploit and utilize Chlorella,the effects of pH value,light intensity concentration of nitrogen salt,phosphorus salt and iron salt on lipid production of Chlorella were studied,and the culture conditions of Chlorella were optimized by the single factor and orthogonal experiments.The results showed that the optimum culture conditions of Chlorella were light intensity of 5 000 lx,pH value of 6,nitrogen salt concentration of 100 mg/L,phosphorus salt concentration of 160 mg/L,iron salt concentration of 100 mg/L,under the above conditions,the lipid output of chlorella was the largest with 615.12 mg/L.
