〔報告〕博物館等における ATP 拭き取り検査によるカビ集落の活性評価について

The prevention of mold outbreaks is one of the most important matters in museums. When mold-like stains are found on the surface of cultural properties or walls of storage rooms, the measures to be taken differ depending on whether the stains are mold or not, and if they are mold, whether they are newly developed or mold traces that occurred in the past.In this study, we investigated the range of intensity of ATP luminescence, whichcorresponds to low mold biological activity, using ATP rapid hygiene monitoring. The changes of ATP luminescence from 63 mold strains collected from museums were measured by periodic ATP rapid hygiene monitoring, while they were incubated on PDA for 147 to 239 days.The luminescence intensity reflected growth curves of the tested mold colonies, and the range of luminescence intensity of the death phase was evaluated. Based on the data of the experiments, ATP luminescence levels higher than 104 RLU/cm2 can be evaluated as high in mold activity, those in the order of 103 RLU/cm2 can be evaluated as low activity, and those below 102 RLU/cm2 indicate the sample is not active mold or it is not mold
