One hundred and fifty six yeast strains were isolated from 160 grass-grown soil samples collected in four different localities in Bratislava, Slovakia. The collection of soil took place in March, May, August, and October. Cryptococcus laurentii, C. albidus, Cyst of ilobasidium capitatum, Sporobolomyces salmonicolor, and Trichosporon cutaneum were the most frequently isolated species from the samples taken in the unpolluted localities Rusovce and Dúbravka. These species represented 92.1 % of totalyeast counts found in these soil samples. Cryptococcus laurentii, C. albidus, Cystofilobasidium capitatum, Debaryomyces castellii, and Rhodotorula glutinis were the most frequently isolated species from the samples taken in the polluted localities Polianky and Mlýnská Dolina. These species represented 93.3 % of total yeast counts there . Yeast densities ranged from 400 to 80.000CFU/g soil. We found that yeasts occurred unevenly in soils during the year. The lowest average number of yeasts was found in August and the highest one in May.
