Abstract

Algae (Selenastrumn capricornutum and Micocystis aeruginosa) were cultivated in the condition of coexistence with various amounts of macrophyte to evaluate the inhibitory effect of macrophyte on algal growth. The effect of water extract and methanol extract from macrophyte on algal growth also was investigated. Egeria densa, Cabomba caroliniana and Myriophyllum spicatum were used as macrophyte. <br> As the macrophyte increased in the algae-macrophyte mixed culture system, algal growth was reduced. It was also shown that the water extract and methanol extract inhibited algal growth and that the inhibitory effect of macrophyte were species-specific to algae. EC₅₀ of macrophyte, water extract and methanol extract for algal growth showed that Myriophyllum spicatum had the most inhibitory effect on the growth of both S. capricornutum and M. aeruginosa among the these macrophytes.
