인골과 인골 주변 토양에 분포하는 세균의 군집구조를 비교하기 위해 부여 오수리 큰독골 유적에서 발굴된 조선시대 회곽묘 인골 중 상대적으로 시료 상태가 좋지 않은 4호 인골과 상태가 양호한 5호 인골 및 주변 토양에서 DNA를 추출하였다. 추출한 DNA의 16S rDNA 염기서열 분석을 수행한 결과, 4호 인골에서 구축된 319개 클론은
Microbial characteristics of bacterial population were investigated in human remains and soil inside the bones in excavated grave no.4 and no.5 at Keundokgol site, Osu-ri, Buyeo. Phylogenetic characteristics of bacterial populations were analyzed by direct extracting of ancient DNA. In this study, based on the 16S rDNA sequences, in case of grave no.4, 319s from human remain were classified into 11 phyla, and 462s from soil were classified into 16 phyla. In case of grave no.5, 271s from human remain were classified into 10 phyla, and 497s from soil were classified into 11 phyla. Especially, Actinobacteria phylogenetic group are dominant group of bacterial populations in grave no.4 and no.5. Also, most of these were analyzed uncultured group. Thus, the discovery of a diversely microbial community and uncultured group was thought to be due to the specificity of the sample. Conclusively the general excavated human bones were contaminated with soil bacteria species their near around. This results contribute to preservation and management of ancient human bone from archaeological sites.
