水棲シアノバクテリア群の高密度集積前後における動粘度特性

Blue-green algae (Cyanobacterial blooms) appear on the surface of eutrophicated lakes and marshes in the intensified solar radiation season, especially in the summer. Cyanobacterial blooms are a phenomenon in which specific aquatic cyanobacteria such as Microcystis, a unicellular organism, emerge and accumulate at high density. The kinematic viscosities of the surface water covered by cyanobacterial blooms appear shows two times higher than that at 0.3m below the surface. The water with accumulated cyanobacterial blooms can be treated as a non-Newtonian fluid due to their viscous biofilm.
