摘要
利用现有的螺旋藻培养基地 ,初步尝试了对海洋单细胞微藻(球等鞭金藻Isochrysisgalbana)的大规模室外培养 ,研究了藻细胞在室内外不同培养条件下的生长规律 ,并对其生化成分进行了分析 ,发现实验藻种对培养条件表现出一定的适应性。在室外条件下 ,细胞内脂类、蛋白质的含量都有较大的下降 ,分别从细胞干重的17.045%和4.412%下降为9.746%和2.254 %。与此同时 ,细胞内糖类含量却大大增加 ,高达干重的30.067 % ,比室内培养增加了25.08 % ,且是所有组分中最高的。室外培养细胞内灰分的含量也高于室内。
The primary investigation on outdoor mass culture of marine unicellular microalga Isochrysis galbana was carried out in open pool. The results illustrated that this alga showed good adaptation to the growth environments. Compared with those grew in indoor, the contents of lipid and protein were all decreased significantly from 17.05% and 4.412% to 9.746% and 2.254% respectively. At the same time, the content of saccaride increase up to 30.067% in dry cells, which is about 25.08% higher than those grown indoors and is the most abundant one among all the biochemical compounds. The quantity of ash was also increased in the cells cultured outdoors.
