摘要
试验结果表明,培养液中锰质量浓度过高或过低都不利于盐藻细胞的生长与物质积累。培养基中锰质量浓度为4.0 mg/L时,盐藻细胞生长、蛋白质合成与β-胡萝卜素积累最多。当培养液中锰质量浓度较高(8.0 mg/L)或较低(2.0 mg/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。在锰质量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 maximum growth,protein synthesize and β-carotene accumulation were observed in Dunaliella salina in the culture medium containing Mn ion at 4.0 mg/L.The high contents of protein and β-carotene were found in each cell of the alga at Mn levels of more than 8.0 mg/L or less than 2.0 mg/L in the culture medium,in which cell density was less and in turn low material accumulation.It is possible that adaptive response of Dunaliella salina forms adverse protein and carotene accumulation under positive and negat...
