Abstract


A total of 69 isolates of yeasts were recorded in the indoor air of the school buildings: 43 in heated rooms and 26 in unheated rooms. Perfect stages prevailed. Fungi isolated in our study belonged to 39 species. These were mostly monospecific isolates although five two-species isolates were noted. Differences in the properties of physiological characters of fungi isolated in both study seasons were observed. As indoor and outdoor air does not mix during the heating season, a specific substrate for prototrophic, non-fermenting yeastlike fungi forms. Acid production allows fungi to dissolve inorganic compounds in building structures and to release needed microcomponents. Abilities to produce carotenoid pigments are clearly promoted in yeast-like fungi living indoor. This may be related to the accumulation of compounds that are indirect stages in the cycle of biosynthesis of carotenoids or a surplus of oxidizing compounds.
