钙离子对螺旋藻生长、光谱特性和藻胆蛋白含量的影响

Effects of Ca^(2+) on the Growth,Spectroscopic Properties and Phycobiliprotein Content of Spirulina

为了对生产上螺旋藻生长中合理使用钙以及富钙螺旋藻的研究与开发提供依据,在接种螺旋藻的Zarrouk培养液中分别添加质量浓度为0~1.0g/L的Ca2+,研究了不同质量浓度Ca2+对螺旋藻生长、光谱特性及藻胆蛋白含量的影响。结果表明:低质量浓度的Ca2+能促进螺旋藻的生长,0.1g/L的Ca2+对螺旋藻生长的促进效果最大,藻胆蛋白的含量也最高;有钙条件下,藻细胞有两个明显的吸收峰,吸收峰分别为藻蓝蛋白620nm,别藻蓝蛋白680nm。当Ca2+质量浓度高于0.1g/L时,对螺旋藻的生长影响不明显。

To reasonably use Ca2+in the production of Spirulinaand make the foundation for the research and development of Spirulina rich in calcium,the authors studied the effects of Ca2+on the growth,spectral characteristics and phycobiliprotein content of Spirulina affter adding different concentration(0~1.0g/L)of Ca2+in Zarrouk culture medium.The results show that lower concentration(0~0.1g/L)of Ca2 +is conducive to the growth of Spirulina,and the concentration of phycobiliprotein is the highest when the optimum concentration of Ca2 +is 0.1g/L.The cells of Spirulinahave two absorbing peaks when Ca2 +was added in the culture medium.The impact of Ca2+on the growth of Spirulinais not very obvious when the concentration of Ca2+is above 0.1g/L.
