Department of Chemistry and Material Technology, Kyoto Institute of Technology, Kyoto 606-8585, Japan.Three kinds of phytoplankton were cultivated, and the contribution of dissolved organic matter (DOM) released from the phytoplankton was examined to clarify the cause of organic pollution of Lake Biwa. Microcystis aeruginosa, Staurastrum dorcidentiferum, and Cryptomonas ovata were evaluated with regard to cultivation. A significant peak (M(w): <3000> Microcystis aeruginosa > Staurastrum dorcidentiferum. These results suggest that the increase of the refractory organic matter in Lake Biwa may be attributed to a change of the predominant phytoplankton.
