Twenty strains which produced geosmin and 2-methy1isoborneol (2-MIB), two major products causing musty odor, were isolated from periphyton of the Tamagawa River. Most of them belonged to fungal species, Aspergillus and Penicillium spp. Others were bacteria including actinomycetes. Two of the strains were examined for their productivity of geosmin and 2-MIB. Their productivity was affected by culturing conditions including pH, aeration and nutrients. Furthermore, when they form spores, they produced geosmin and 2-MIB at high levels.
