| Outline of Research at the Start |
A. FY2023 outline of research: The degradation of plastic under UV will be clarified; Participate 2 international conferences; Publish 1 research paper.
B. FY2024 outline of research: The bacteria involved in to plastic biodegradation will be identified; Publish 1 to 2 research papers.
|
| Outline of Annual Research Achievements |
- The biodegradation tests at field and lab condition for several plastic types were completed in a mangrove forest in Vietnam (Can-Gio, Ho Chi Minh City).
- The rhizophere microorganisms, including bacteria and fungi, in the mangroves forest were isolated.
- The clearance zone test were carried out to identify the plastic degradable microorganism for each polymer.
- Based on the weight loss after the tests, the biodegradability of the plastics was in order of PHBH > PCL > PBSA >> PBS.

| Current Status of Research Progress |
Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The research progress is on schedule.
|
| Strategy for Future Research Activity |
- In the next steps, the plastic biodegradable bacterial species will be identified using DNA sequencing techniques.
- The biodegradation test for the investigated polymers will be carried out in both dry and rainy season.
- The biodegradation test using new BOD sensors will be conducted.
