水葫芦提取植物蛋白废液培养小球藻初步研究

为提高小球藻培养的经济效益和高效资源化综合利用水葫芦,初步研究了水葫芦提取植物蛋白废液对小球藻生长、叶绿素和蛋白质含量的影响。研究结果表明,光照条件下,培养藻液中添加不超过6%体积的水葫芦废液,小球藻的生长速度及藻体叶绿素和蛋白质含量均随废液添加量的增加而提高,即使培养藻液中不添加任何营养元素而只添加1%～6%体积的废液,小球藻的生长速度及藻体叶绿素和蛋白质含量即可达到和超过基础营养液培养组的小球藻,说明水葫芦提取植物蛋白的废液可极大地提高小球藻培养的经济效益,甚至可完全替代营养盐的添加;但在无光条件下,添加废液对小球藻生长无效,说明未经处理的水葫芦废液尚不能作为小球藻异养培养的营养源。

A Preliminary Study on the Culture of Chlorella Vulgaris with Waste Solution of Eichhornia Crassipes

In order to improve the economic benefits of Chlorella vulgaris culture and efficient utilization of Eichhornia crassipes,effect of waste solution of Eichhornia crassipes on the growth,the chlorophyll and the protein content of Chlorella vulgaris were studied preliminarily.The results showed that under light conditions,the growth,the chlorophyll and the protein content of Chlorella vulgaris increased with the increase of waste solution volume from 0% to 6%,and even if there is nothing but waste solution volume from 1% to 6% in the algae solution,the chlorella growth rate and chlorophyll and protein content could achieve or exceed the cultured in basic nutrient solution,which proved that the waste solution can greatly improve the economic benefits of chlorella culture,or even completely replace the nutrients;but without light conditions,it is invalid and can not act as nutrients source of heterotrophic.
