Abstract
For the purpose of deciding the temperature and length of time for the incubation of the airborne fungal particles collected by biological particle samplers, the hyphal growth of Cladosporium cladosporioides var. and radial growth rate of colonies of 12 genuses of fungi acutully collected in ordinal indoor environments were experimentally analyzed. The hyphal growth rate was determind under microscopical conditions at 25℃ and the colony growth rate was by the direct measurement, at the temperature conditions of 4℃, 10℃, 15℃, 20℃, 25℃, 30℃, and 37℃. The colony growth rate were high in the range of 20〜30℃ and hyphal and colony growth rate at 25℃ coincided for the Cladosporium species. The conclusion is that the incubation at 25℃ in temperature and 72 hour for length of time is desirable though proper judgement is required in growing state.
