초록

새로운 pine needle agar를 이용하여 15종의 박테리아를 솔잎퇴적물에서 추출하여 동정하였다. 이들 박테리아는 lignin biodegradation에서 주로 유도되는 방향족 탄화수소물질을 $\beta$-ketoadipate pathway의 ortho-cleavage를 이용하여 분해하는 것으로 밝혀졌다. 나아가서 이들 박테리아에 의한 여러 종의 방향족 탄화수소물질 분해에 관해서도 조사하였다. 본 연구는 솔잎 퇴적물에 존재하는 박테리아 종들이 방향족 탄화수소물질을 분해할 수 있는 대사능력을 가지고 있다는 것을 검증하였다.

Using a novel pine needle agar, fifteen bacterial species were isolated from pine litter. These bacteria were able to degrade aromatic hydrocarbons derived from lignin and utilize the ortho-cleavage of the $\beta$-ketoadipate pathway to degrade protocatechuate or catechol. A different utilization array of aromatic hydrocarbons by these bacteria was also determined. This study provides the information on bacterial species living in pine litter and suggests that these bacteria have metabolic abilities to utilize aromatic hydrocarbons derived from lignin biodegradation.
