摘要
利用绿光、蓝光、红光、白光(对照)4种光质培养紫球藻,通过测定藻密度和藻液的光吸收以比较不同光质对紫球藻生长的影响,同时测定藻胆素含量,可溶性总蛋白的含量．实验结果表明:绿光培养条件下紫球藻的生物产量、藻胆素、可溶性总蛋白的含量最高,蓝光次之,而在红光培养条件的紫球藻生长最缓慢．实验数据为紫球藻的高密度放大培养提供依据．
Effects of different light qualities（green light,blue light,red light,and white light） on growth of Porphyridiumi cruentum were studied by measuring the alga density,optieal absorption of algae water,eontent of phyeobilin and soluble total protein. The results indieated that the biomass,eontent of phyeobilin and soluble total protein were highest under green light, eompared with the other treatments. The blue light treatment took the second effeet. On the eontrary,the growth of Porphyridium cruentum was lowest under red light treatment. The result suggested that green treatment eould aeeelerate the growth of Porphyriddium cruentum. The information in the present study is important to improve the culture condition and enlarge the biomass of Porphyridium cruentum in the future.
