| benthic cyanobacteria (oscillatoriaceae) that produce microcystin-lr, isolated from four reservoirs in southern california. | cyanobacteria that produce the toxin microcystin have been isolated from many parts of the world. most of these organisms are planktonic; however, we report on several microcystin-producing benthic filamentous cyanobacterial isolates from four drinking-water reservoirs in southern california (usa): lake mathews, lake skinner, diamond valley lake (dvl), and lake perris. some samples of benthic material from these reservoirs tested positive for microcystin by an elisa tube assay, and all the posit ... | 2007 | 17126876 |
