도 2는 본 발명의 판토에아 속 PL-1 균주를 투과전자현미경(TEM)으로 관찰한 것이다.
도 3은 본 발명의 판토에아 속 PL-1 균주의 DPD (AI-2 신호분자) 농도를 감소시키는 활성을 측정한 결과이다.
도 4는 본 발명의 판토에아 속 PL-1 균주를 배양함에 따라 DPD (AI-2 신호분자)의 농도가 감소함을 보여주는 결과이다.
도 5는 본 발명의 판토에아 속 PL-1 균주와 기존 DKY-1 균주의 펠렛(pellet)에서 DPD (AI-2 신호분자) 농도를 감소시키는 활성을 측정하여 비교한 결과이다.
도 6은 본 발명의 판토에아 속 PL-1 균주와 DKY-1 균주의 상등액(supernatant) 부분에서 DPD (AI-2 신호분자) 농도를 감소시키는 활성을 측정하여 비교한 결과이다.
