摘要
实验研究了不同浓度的钼对盐藻细胞生长物质积累的调控作用。结果表明,培养液中供给钼过多或过少都不利于盐藻细胞的生长与物质积累。以培养基中60μg/L的钼浓度对盐藻细胞生长、蛋白质合成与β-胡萝卜素积累的促进作用最大。这一钼浓度可用于盐藻的生产性培养。当培养液中钼浓度较高(80μg/L)或较低(20μg/L)时,单个盐藻细胞中的蛋白质与β-胡萝卜素含量较高。但此时,因培养液中细胞密度较低,盐藻细胞积累的物质总量仍然较少。在钼浓度较高或较低的逆境条件下,盐藻可能通过适应性反应形成了逆境蛋白质与胡萝卜素等。
The experiment study regulation of different consideration Mo to growth and material accumulation of Dunaliella salina. The result shows more or less Mo goes against Dunaliella salina cell growth and material accumulation. Mo of 60μg/L is advantageous to growth,protein synthesis and β - carotene accumulation of Dunaliella salina in culture medium. It is used to culture Dunaliella salina. When the concentration of Mo is 80μ/L or 20μg/L,the content of protein and β - carotene in each cell Dunaliella salina is higher. But Dunaliella cell density is lower right now, the total material accumulation of Dunaliella salina cell is less. It may be that adaptive response of Dunaliella salina form adverse protein and carotene under the rich or poor Mo stress.
