Frequent outbreak of diatom bloom in eutrophicated rivers has increasing become a serious problems around world. While many studies have been focused on the blue-green algae bloom in lakes and reservoirs, knowledge on diatom bloom in rivers has lagged far behind. In order to understand the formation and the mechanism of diatom bloom in rivers, the present study investigated the dynamics of diatom bloom in Han-river, in particularly, the growth physiology of dominant diatom isolated from the river. The main ...
