Abstract
This study was conducted to examineboth the type of wood decay and the degree of degradation for the waterlogged woods (Alnus spp. and Fraxinus spp., about 5,700~5,900 year old), which were excavated at Higokri, Pyungteak in the west-coastal region of Korea. The transmission electron microscope (TEM) observation indicated the degradations by soft rot and bacteria were common in both woods. Erosion bacteria attacked gradually and irregularly from the secondary layer to compound middle lamella and often produced the cavity which was similar to soft-rot cavity but much smaller ones. Tunneling bacteria decomposed mainly
경기도 평택 희곡리 토탄층(약 5,700~5,900년전(前))에서 수침상태로 출토된 물푸레나무속 1종과 오리나무속 1종을 대상으로 전자현미경 관찰을 통하여 수종에 따른 분해정도와 형태를 조사하였다. 관찰결과 두 수종 모두 연부후와 박테리아에 의한 세포벽 공격형태와 분해형태는 거의 유사하였다.
