Outline of Final Research Achievements

Malodorous substances were generated from the documents damaged by the tsunami in 2011 during the stabilization treatment and storage. To improve the treatment process, the water used for treatment was sampled at each step and measured ammonia ion concentration, sulfide ion concentration, chloride ion concentration, pH, bacterial content, and residual protein amount. The malodorous substances were carboxylic acids such as butyric acid, sulfides and ammonia gas.
As the temperature of the water used for the treatment was raised for the purpose of quick desalination, it was found that the temperature favorable for microbial growth lasted 8 hours. The amount of bacteria in the treated water became 100 times to 100000 times after 20 hours immersion. Before cleaning the documents with neutral detergent, soil bacteria were mainly found. After washing, skin resident bacteria accounted for the majority. It was found that most of the salt escaped by dipping in water once.
