| 摘 要： | 选择无机胶体粒子Fe(OH) 3 胶体、伊利石胶体及其与金属铁和铜 ,对中肋骨条藻进行了培养实验。结果表明 :在培养介质中加入Fe(OH) 3 胶体后 ,在低添加量时可通过Fe(OH) 3 胶体提供满足微藻的生长所需的铁 ,从而提高其生长速度。但在较高添加量时 (>0 .5mg/L) ,由于胶体物质的吸附特性 ,微藻的生长受到抑制。Fe(OH) 3 对中肋骨条藻的最佳的添加量在 0 .2 5～ 0 .5 0mg/L之间。中肋骨条藻在加入伊利石胶体液时 ,微藻的生长均产生明显的抑制作用。通过伊利石胶体对培养介质中铁离子和铜离子浓度的调节控制作用 ,可直接影响到中肋骨条藻的生长。

| Abstract: | Skeletonema costatum was cultivated with the addition of inorganic colloid substance of Fe(OH) 3 colloid and illite colloid and trace metals of iron and copper. The results showed that cell abundance and growth rate were promoted with a few Fe(OH) 3 colloid particles; however, they were restrained with more colloid (>0.5mg/L). The optimal quantity for Skeletonema costatum ranged from 0.25mg/L to 0.50mg/L. When some illite colloid was added, microalga growth was inhibited. Through the adjustment of illite colloid for the concentration of iron and copper, the growth of Skeletonema costatum was influenced directly. |
