Three kinds of fungi were cultured on various media (including different 30 surfactants, anionic, nonionic, amphoteric, and cationic surfactants) and a comparison of their growth was made. The growth of all three fungi was inhibited by anionic, amphoteric, and cationic surfactants. In particular, no colonies of these fungi were found on 0.25% of these surfactants and only small colonies were found on 0.05%. On the other hand, although two fatty acid-amide type nonionic surfactants inhibited the growth of the three fungi, no inhibition on the their growth was found on media including other nonionics. For example, fatty-acid ester type nonionics promoted the growth of all three fungi. In particular, <i>Scolecobasidium constrictum</i>, a dominant fungus in washing machines, grew well on media including polyoxyethylene-alkylether nonionic surfactants, in contrast with <i>Cladosporium cladosporioides</i>, a common fungus in indoor environments. Fatty-acid amide type surfactants were noticed for their potential to be exploited in detergent for fungus-free washing machines.

Far more studies on lichens as bioindicators of air pollution have been done in Europe and North America than in Japan. It is therefore necessary to grasp the background of European scicnce in this field in order to perform these difficult studies. Such studies shoud help to clarify the comprehensive influence of many air pollutants on lichens, and recent changes in the environmental situation. Remarkable studies carried out in Europe over the last 30 years, and recent reports, including those on acid rain, are reviewed. The authors discuss how to actually perform studies of lichens in Japan, based on their investigations in and around Osaka City.
