Outline of Final Research Achievements |
In this study, we have analyzed a new phosphorus cycle in river water by a polyphosphate-accumulating bacterioplankton (IRD18C08 bacteria) which is belonged to a new taxon. This study has the following aims: (1) to estimate biomass of IRD18C08 bacteria by catalyzed reporter deposition-fluorescence in situ hybridization (CARD-FISH), (2) to monitor phosphate-phosphorus concentration in river water, and (3) to estimate phosphate-phosphorus uptake per unit cell of IRD18C08 bacteria. These results reveal that the IRD18C08 bacteria may contribute to about 0.6% dynamics of phosphate-phosphorus cycle in river water.
