Abstract:

The fresh water microalgae Microcystis aeruginosa has been examined for its chlorophyll-a and antioxidant enzymatic activities in different nitrate and phosphate concentrations. In the experiment, M. aeruginosa were cultured 28 days at 18°C, 25°C and 30°C in various light intensity. The maximum chlorophyll-a content was 33.79 (mg/L) in phosphate (460 µM) at 30℃. Superoxide dismutase (SOD) was significantly higher of 66.53% in phosphate (980 µM) at 30℃. DPPH radical scavenging activity of 78.16 % in the nitrate (329.5µM) at 18℃. The results showed that the maximum chlorophyll-a recorded at 30℃ from N:P, P and N respectively.  DPPH increased with nitrate concentration during the lower temperature and the SOD increased with phosphate in highest temperature. Chlorophyll- a content significantly compared with 18℃ and 30℃ (P < 0.05).    


Keywords: Microcystis aeruginosa, Nitrate; phosphate, Chlorophyll-a, DPPH radical-scavenging activity, Superoxide
