Abstract

Biodegradation behavior of poly(butylene succinate-co-butylene adipate) (PBSA) was examined when PBSA was buried in the natural soil and the soil inoculated with Burkholderia cepacia after sterilization. After 80 days of the soil burial test at room temperature, the PBSA film buried in the natural soil lost 34.0% of its intial weight, while the same film lost 59.2% of its initial weight when buried in the sterile soil inoculated with B. cepacia. The optical and SEM observations of the surface morphology of the PBSA film also indicated that the surface erosion and rupture took place faster when the film was buried in the sterile soil inoculated with B. cepacia compared to the film buried in the natural soil. Viable cell number in the natural soil and that the sterile soil inoculated with B. cepacia increased by a factor of 6~7 and 10~14, respectively as compared to the initial viable cell number.

자연 토양 및 Burkholderia cepacia를 접종한 멸균 토양에 PBSA film을 매립하여 PBSA의 생분해 특성을 조사하였다. 상온에서 80일간 매립 시험을 실시한 결과, 자연 토양에서는 PBSA film의 34.0%, B. cepacia를 접종한 멸균 토양에서는 59.2%의 질량 감소가 일어났으며 PBSA film의 표면 형태 변화도 B. cepacia를 접종한 멸균 토양에 매립한 경우가 자연 토양에 매립한 경우에 비하여 PBSA film 표면의 침식 및 균열이 더 빠르게 일어났다. PBSA film을 매립하였을 때 80일 후 자연 토양에서 세균수는 6~7배 증가한 반면 B. cepacia를 접종한 멸균 토양에서 개체수는 10~14배 증가하였다.
