Biodeterioration in Gyeongjuseokbinggo

경주석빙고 내부의 생물 분포에 관한 연구

This paper presents the results of a study carried out on the diversity of the living microorganisms colonizing the inside of Gyeongjuseokbinggo(Treasures 66) and their effect on the substrate. The inner walls and the arch were first examined with the unaided eye. Green thick mats of algae and microorganisms covered the great part of the walls. For the laboratory research this green biogenic layer and the next soil layer were collected by scraping the walls and the arch under aseptic conditions. The material was then cultured in laboratory. In result, many different species of bacteria, fungi, algae, cyanobacteria and actinomycetes were isolated from the samples.
