| 摘 要： | 采用正相悬浮聚合法制备了聚苯乙烯－二乙烯苯磁性微球。由于微球表面的聚苯乙烯是疏水性材料，可用于制定微生物细胞表面的疏水性。用聚苯乙烯磁性微球吸附法测定了不同生长期盐藻细胞的表面疏水性，以及pH值、NaCl浓度、Fe^3 浓度、（NH4）2SO4浓度对盐藻细胞疏水性的影响。结果表明，盐藻细胞表面具有疏水性质， 其疏水性与细胞生长阶段及环境条件有关。

| Abstract: | The surface of magnetic polymer microsphere that was made from polystyrene is hydrophobic. It can measure the hydrophobicity of microbial cells. In this work, the microsphere, which was made from styrene and divinylbenzene, was prepared by suspension polymerization. The surface hydrophobicity of Dunaliella salina cells was measured in different growth phase and different culture conditions with pH, NaCl concentration, Fe3+ concentration and (NH4)2SO4 concentration. The results showed that the surface of Dunaliella salina cells has hydrophobicity and the hydrophobicity changed with cell growth phase and culture conditions. |
