A STUTY ON THE ADAPTABILITY OF POD OF SPIRULINA (ARTHROSPITA) TO TEMPERATURE AND pH

Abstract

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.

Key words: Spirulina(Arthrospira), peroxydase (POD), temperature, pH value, adaptability
