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.
