为提高雨生红球藻的生物量以及细胞内虾青素的积累量,通过不同光源、不同光照强度照射培养藻细胞。研究表明,在总光强为2500lx,红光与白光的强度比例为2：1时,雨生红球藻干重可以达到0.98g/L,比单独使用白光和红光照射下分别提高了36.11%和15.91%。在雨生红球藻转化产虾青素阶段,对比蓝光LED、日光灯以及两者的组合光源照射转化的结果,发现在总光强为7000lx,蓝光与白光的强度比例为3：1时,雨生红球藻中虾青素的积累量为39.79mg/L,明显高于单独使用白光与蓝光转化下的产量。

In order to increase the cell concentration and the accumulation of astaxanthin,the effects of different light intensity of diverse illuminants were studied on cell growth and accumulation of astaxan-thin.The results were as follows:in condition that the light intensity was 2500lx and ratio of red light and white light 2:1,the cell concentration reached 0.98g/L,which increased by 36.11% and 15.91%compared with illumination under only fluorescent lamps and red LEDs,respectively.While in the phase of astaxanthin production,combined illuminant was the optimal illuminator among the fluores-cent lamps,blue LEDs and combination of them.And under illumination with combined illuminants at 7000lx,and proportion of blue light to white light 3:1,the astaxanthin concentration reached 39.79 mg/L,which was apparently higher than that illuminated only with fluorescent lamps or blue LEDs.
