The thermal conditions preventing the growth of 4 kinds of hygrophile fungi on building materials intentionally contaminated with egg yolk are described. Exposure tests for building materials of tatami mat, which is the Japanese traditional flooring, made of straw mat, plywood, wallpaper and so on, swabbed with a suspension of fungal spores and yolk, were conducted. Fungal species of Aspergillus niger, Penicillium citrinum, Alternaria alternata and Cladosporium cladosporioides, frequently detected in Japanese dwellings, were used in these experiments. Exposure conditions of temperature and relative humidity were covered extensively, ranging from 0℃ to 45℃ and from 45% R. H. to 95% R. H.. Minute observation for the colonies formed were made over 12 days under each thermal condition. These 4 hygrophile moulds grew and formed colonies under the conditions ranging from 20℃ to 30℃ or above 90% R. H.. On the other hand, none of these moulds grew under the conditions below 5℃ or beyond 45℃ regardless of the relative humidities, or the conditions below 80% R. H. regardless of the temperature.
