Description

폴리-β-하이드록시 알카노에이트(PHA) 공중합체 및 그 제조방법, 이를 생산하는 미생물과 PHA 공중합체의 고분자 블렌드
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 1도는 PHA 공중합체의 정량을 위한 PHB 표준정량 직선이다. PHA의 정량을 위해 PHB를 표준 시료로 하여, CC 스펙트럼을 분석, 면적을 비교, 계산함으로서 PHA의 양을 계산한다.
제 2도는 PHA 공중합체의 GC 스펙트럼이다. PHA를 메틸 에스테르화 하여 GC를 분석한 결과 각 피이크는 PHA를 구성하는 모너머들의 메틸 에스테르 분자이다.
제 3도는 GC 스펙트럼 상에서 PHA 공중합 고분자의 각 모노머의 보지시간(Retention Time)의 Log 값과 탄소수와의 관계를 나타낸다. 탄소수에 비례하여 Log(RT)값이 증가함을 보여준다.
