摘要: 研究了不同浓度的硫酸铵[(NH4)2SO4]和乙酸铵(CH3COONH4)对螺旋藻生长的影响. 实验结果表明,从实验设计的浓度梯度来看,螺旋藻能耐受的硫酸铵和乙酸铵浓度分别为0.5和0.6 g/L,相应的铵氮含量分别为212和109 mg/L. 培养结束时硫酸铵和乙酸铵的去除率分别为85.38%和99.7%. 添加的乙酸铵几乎全部被螺旋藻利用,并且蛋白质含量明显提高.

Abstract: The effects of different concentrations of ammonium sulphate and ammonium acetate in the medium on the growth of Spirulina platensis were studied. The results showed that the ammonium salts as nitrogenous resources can be used by S. platensis effectively. The endurable concentrations of ammonium sulphate and ammonium acetate by S. platensis were 0.5 and 0.6 g/L, and related concentrations of NH4+-N were 212 and 109 mg/L, removal efficiencies of NH4+-N were 85.38% and 99.7% respectively. The content of protein was increased markedly when ammonium acetate was added to the medium.
