中文摘要: |
通过室内控制实验,研究了不同的曝气比率对蛋白核小球藻(Chlorella vulgaris)生长过程影响,构建了曝气比率与ODmax、μmax、Cmax的适配曲线。实验设置0、2%、10%、20%、30%、50%、70%共计7组曝气比率,在1000 lx光强和20℃条件下,采用BG-11培养基培养小球藻至稳定生长。结果显示,适宜的曝气能促进小球藻生长,其最适曝气比率为20%,过量曝气会抑制小球藻生长;曝气比率(x)与ODmax、Cmax、μmax拟合方程分别为:ODmax= 170.63x3-231.83x2 +84.341x +1.8439 (0

英文摘要: |
The study aimed to investigate the effects of varying aeration rates (0, 2%, 10%, 20%, 30%, 50%, and 70%) on the growth of Chlorella vulgaris. The experiment was conducted under 1000 lx light intensity at 20℃, and the Chlorella vulgaris was cultivated on the BG-11 culture medium to stable condition. Fitted curves between aeration ratio and the maximum optical density (ODmax), the maximum growth rate (μmax) and the maximum concentration of daily biomass (Cmax) were created. The results showed that appropriate aeration promoted the growth of Chlorella vulgaris, with the best aeration rate of 20%, while the excessive aeration inhibited the growth; the mathematical relationships between aeration ratio and ODmax, μmax and Cmax simulated by cubic curve equation were shown as follows: ODmax= 170.63x3-231.83x2 +84.341x +1.8439 (0
