초록

유류 오염된 해양 갯벌에서 분리한 다환방향수소족(PAHs)을 분해하는 균주들로부터 인디고로 생물전환 활성을 가진 것으로 예측되는 Azoarcus sp. TSPY31과 TSNA42 균주를 동정하였다. 이 두 균주의 유전체 분석을 실시한 결과, 모두 하나의 완전한 chromosome으로 구성되며, TSPY31은 총 4,572,082 bp에 G + C 함량은 63.2%로 이루어져 있고, TSNA42는 4,886,934 bp에 G + C 함량은 62.8%이었다. 이 두 균주 모두 인돌을 인디고로 전환하는 효소인 styrene monooxygenase를 각각 2 copy씩 보유하고 있는 것으로 확인되었다.

Azoarcus are known to contain bacterial strains usually found in contaminated areas. Two strains of Azoarcus sp., TSPY31 and TSNA42, were isolated from oil-contaminated marine tidal flats, and their genomic structures were analyzed. The genomes of both TSPY31 and TSNA42 were composed of a single complete chromosome of 4,572,082 bp (G + C content: 63.2%) and 4,886,934 bp (G + C content: 62.8%), respectively. Both genomes were found to contain two copies of styrene monooxygenases that are predicted to be responsible for converting indole to indigo.
