| Outline of Final Research Achievements |
The production of multi-layered bio-cement, which was the main objective of the project, could be carried out. We were also able to confirm that up to three layers of biocement could be reliably implemented. When the multi-layered biocement collapsed, we expected to observe the collapse of one layer at a time, but the entire biocement collapsed. Eelgrass germination and growth from the biocement granules were confirmed. However, there were some individuals that did not germinate, probably due to the condition of the seeds, and it is necessary to further investigate the cause of this while examining the conditions.Chemical analysis and metagenomic analysis of microorganisms were conducted in tanks and in natural sea sand in the multi-layered bio-cement. Although the bottom sediment conditions were not significantly altered, the ability to make gentle adjustments was confirmed.

| Academic Significance and Societal Importance of the Research Achievements |
ブルーカーボンという言葉が認知されはじめ、海洋での炭素固定に関して産業界が着目するようになってきた。我々が開発した多層化バイオセメントは海洋環境に造粒物が残存せず、また海底底質内に適切なミネラルや栄養素を種子とともに届けることができる。
また、ゴルフボールよりも小さな砂の塊は、子供でも手軽に海中に投げ入れることができるだけでなく、足が不自由で海の保全活動に参加できなかった方にもその機会を提供できる設計となっている。海洋環境保全の取り組みに、誰もが参加できる仕組みづくりの一助にもなると考えている。
