| Research Abstract |
Several bio-degradable plastic degradation bacteria were isolated from Kuril-Trench(depth 3500-4800m) and Japan-Trench(depth 5000-7000m). The isolated bacteria were shown as psychrophilic and piezophilic growth properties, and were able to degrade the bio-plastics at low temperature and high-pressure conditions. Using those isolates, the "continuous high-pressure cultivation and bio-plastic degradation evaluation system"was developed, and we elucidated it's availability.
