摘要: 以毛乌素沙地碱湖特有的钝顶螺旋藻S1、引进的钝顶螺旋藻S2和极大螺旋藻S3为材料,采用愈创木酚法探讨温度和pH值对其POD活性影响。结果表明:S1、S2和S3的POD活性分别为480 U/g.FW、447 U/g.FW和408 U/g.FW(25℃、pH 6);最适温度分别为30℃、40℃和40℃;最适pH均为6.0。S1的POD对温度和pH适应范围宽,在低、高温、强酸和强碱下的活性均比引进种的高。

Abstract: Effects of temperature and pH on activity of POD of endemic Spirulina platensis(S1) from alkaline lake in Mo Us Sandy Land, imported S. platensis (S2) and S. maxima (S3) were investigated by means of guaiacol colorimetry. The results showed that the activity of POD of S1, S2 and S3 are respectively 480 U/g. FW、447 U/g. FW和408 U/g. FW (25℃ and pH 6);Optimum temperature are 30℃、40℃和40℃;Their optimum pH are 6.0 in common. The adaptability range of POD of S1 to pH is wide, and higher than that of the imported one under both low and high temperature and both strong acid and base.
