| Outline of Final Research Achievements |
Blue-green algae are distributed worldwide, regardless of country and region, and are one factor posing a serious universal risk to water quality. We studied the effects of water surface and water spatial changes on the chemical ecology of blue-green algae, by using quantitative data of 110 chemicals required for biological activity. Changes in the chemical ecology of blue-green algae were more pronounced due to differences in surface level and medium depth-water which represented vertical motion of cells, as opposed to daytime and nighttime differences related to photosynthesis. With only a maximum difference of 0.5 cm in water depth, it was revealed that concentrations of chemicals which blue-green algae biosynthesizes and metabolizes differed greatly. This concentration difference reflected requirements for cell proliferation.
