Abstract

The biodeterioration with blue-green algae has been studied since 1997 up to 2000 in the tomb of King Mooryong in Kongiu, Korea. Biodeterioration in the tomb initially started from the formation of micro-organismic biofilm that had been suggested to make minor changes on the stone surface. This study revealed that the biofilm formed by microorganisms could result in permanent damages on stone cultural properties. The application of a chemical, 'K2Ol', developed by the author successfully removed fouling of biofilm on the surfaces of stone cultural properties. When small pieces of granite stone were embedded in the solution to study the side effects of the chemicals for a period of three months, the mechanical stability was 0.97 compared to control and there was no change in color. Biodeterioration is one of the most harmful factors that decrease the value of stone cultural properties but it may be treated with a development of proper chemicals.
