Measures such as intermittent UV irradiation have been applied since March 2009 to control microoraganisms on the plaster. Growth of most fungal mycelia was suppressed effectively. In the survey of 2010, dark colored fungi such as a black basidiomycetous anamorphic fungus Burgoa sp. were observed, but there was not much problem as a whole. Many species of microorganisms were isolated from six samples from the stone chamber interior at the sampling in October 2011. While the microbiota was almost similar to the ones which had been observed in surveys of the last several years, percentage of the isolates of dark colored fungi seemed higher this year. Gram-negative bacterial species similar to the ones of last year were isolated again. Acetic acid bacteria, Gluconacetobacter spp., which were assumed to be involved in severe deterioration of the plaster,were not isolated in the survey of both 2010 and 2011, after applying intermittent UV irradiation, suggesting that the bacteria are suppressed by the control. However,as a whole,microorganisms seem to survive at places where sufficient UV light does not reach, such as inside cracks of the stones,inside mud layer and inside gels of biofilm,though they do not cause obvious damage.}, pages = {167--171}, title = {〔報告〕キトラ古墳の微生物調査報告(2011)}, year = {2012} }
