| Outline of Final Research Achievements |
In this study, I focused on the microbial carbon pump, which is the one of the most important carbon sequestration systems as well as the biological carbon pump in the ocean. I tried to develop the method using semi permeable membrane to assess the production of refractory dissolved organic matter (DOM), especially humic-like fluorescence DOM (FDOM), from particulate organic matter (POM). Then I assessed the production of protein-like and humic-like FDOM from the POM using incubation experiment. In addition, I evaluated the interaction among the labile organic matter (used several amino acids and monosaccharides as a model DOM), bacterial community, and the humic-like FDOM production.
