本文研究了在相同培养条件下，11株小球藻的生长、光能利用率、色素以及蛋白质含量。实验结果显示，分离自成都本地的小球藻C5生长速度上具有很强的优势，达到0.031 g/(L?d) ，可溶性蛋白含量为44.73%，叶绿素含量达到29.05 mg/g，类胡萝卜素的含量达到15.35 mg/g。因此，实际生产过程中可以选用小球藻C5作为生产藻种。

Growth pattern and biochemical composition of eleven strains of Chlorella were studied under controlled culture situation. The chemical constituents were analyzed in terms of growth, light use efficiency, pigment and protein. Of eleven species, the C5 strain showed higher growth rate, about 0.031 g/(L?d). The content of soluble protein was 44.73%. The pigment concentration of chlorophyll a and carotenoid was 29.05 mg/g and 15.35 mg/g, respectively.
