Abstract

Microcystis aeruginosa is a species of unicellular cyanobacterium which synthesizes toxic microcystin. This work reports that the photosynthesis and growth of M. aeruginosa is inhibited by Scenedesmus obliquus when the two species are cultivated in BG-11 medium, even when the ratio of cell numbers between S. obliquus and M. aeruginosa is reduced to 1:100, or when M. aeruginosa was cultivated in a filtered medium in which S. obliquus had previously grown. As a result, the net photosynthesis and chlorophyll a content of M. aeruginosa decreased.
