【摘要】 为进一步探讨2个不同来源钝顶螺旋藻的砷富集特性,明晰藻液砷浓度与生长、产量及藻粉砷含量的对应关系,在不同质量浓度砷溶液中培养鄂尔多斯钝顶螺旋藻与引进螺旋藻藻种,通过比较2藻种生长情况、藻粉的干重及藻粉中砷的质量比,分析2藻种对砷的适应性和抵抗性。结果表明,在0~0.32 mg/L的砷环境中,2藻种生长均没有受到抑制,当地藻种产量高于引进藻种,在各砷浓度下鄂尔多斯钝顶螺旋藻藻粉砷质量比明显低于引进种。更多还原

【Abstract】 Comparative study is carried out on the dry weight, the growth(OD560)and the arsenic content of the spirulina powder at different arsenic concentrations for the Spirulina platensis from the alkaline lake of Erdos plateau and the introduced species to find out the characteristics of the arsenic enrichment and analyze the arsenic adaptation and the arsenic resistivity of two spieces of Spirulina platensis. The results show that the growth of two spieces of Spirulina platensis is not inhibited, the production of Spirulina platensis from Erdos is higher than the introduced, and the arsenic content of spirulina powder is obviously lower than the introduced at different arsenic concentrations.更多还原
