摘要
通过对盐藻细胞的浓缩倍数和采收率的测定,考察了藻液pH值、气体流速(vg)、藻细胞初始浓度(C0)对盐藻细胞的泡载分离采收性能的影响,优化了盐藻细胞泡载分离采收条件. 结果表明:在vg为60 ml/min,C0为2.58×105 个/ml,pH值为7.5的条件下,盐藻细胞泡载分离的采收率达90%～94%,浓缩倍数达30～34. 泡载分离是分离浓缩盐藻细胞的一种简便、高效的方法.
By determining the enrichment factor and total yield of Dunaliella salina cells, the effects of different operational conditions, such as gas flow rate (vg), initial cell concentration (C0) and pH on the feasibility of foam flotation of Dunaliella salina cells were investigated. By the way, the treatment conditions were optimized. The experimental results showed that when vg was 60 ml/min, C0 was 2.58105 cells/ml and pH was 7.5, foam flotation had a high concentrating efficiency for total yield (90%~94%) and the enrichment factor reached 30~34. The foam flotation may be a simple and highly effective method for concentrating Dunaliella salina cells.
