문화재로부터 선별된 미생물의 동정 및 바이오매스분해 활성 확인

초록

Ancient cultural heritage is very important in historicalworth which they must be preserved in. However, theyare rotten and disintegrated easily by various microorganismslike fungi and bacteria because they are mostly made up ofwood and paper. In order to control these microbes, we needto investigate these microbes to maintain historical worth ofancient cultural heritage. We collected several samples fromsurface of ancient documents and wooden artifacts. And thenmicroorganisms were isolated from the samples and identifiedthrough sequencing of 16S ribosomal RNA or internaltranscribed spacer region. As results of sequencing, two bacterialstrains (E-1, O-1) were identified as Staphylococcushominis and S. epidermidis and four fungal strains (A-1, M-1,M-2, K-1) were identified as Schizophyllum commune, Peniophoraincarnata, Cephalotheca foveolata, Aspergillus niger. Among them, A-1 strain showed relatively higher celluloseand CMC degrading activities and K-1 strain showed relativelyhigher xylan degrading activity than other strains.
