Two freshwater and two marine alg;tl species were grown in intensive contiimous cultures at a fixed dilution rate of 0.5 ·day -I, but at varying pH levels in the range 7.6 to 1C.6. Both freshwater species, Scenedesmus obliquus (Turp.) Kutz. and Chlorella vulgaris Beij., grew up to pH 10.6 although C. vulgaris was more adversely affected by alkaline pH than was Scenedesmus obliquus. Of the marin...

This study was performed to compare the efficiency of six microalgae namely Dunaliella tertiolecta, Tetraselmis suecica, Nannochloropsis oculata, Chaetoceros sp., Chlorella sp. and Spirolina sp. on the growth, survival rate and reproduction efficacy in Artemia urmiana in laboratory conditions. Artemia cysts were harvested from Urmia Lake and hatched according to the standard method. Live microa...
