Abstract The distribution of microorganisms in four soil samples taken near Casey Station, Wilkes Land, and on Dewart Island, Frazier Islands (East Antarctica), was studied using isolation cultures at different temperatures. The fungal assemblages comprised Penicillium, Alternaria, Cladosporium, Phoma, Verticillium, Phialophora, Candida and Rhodotorula. Microalgal Chlorophyta were also common. Among the bacteria representatives of cyanobacteria, Staphylococcus, Bacillus, Pantoea, Streptomyces, Micromonospora, and coryne- and nocardioform species were found. Some of the isolated actinomycete strains, determined as Arthrobacter, Rhodococcus, Streptomyces and Micromonospora, produced extracellular substances with antibacterial and antifungal activities. Their potential as biological agents against phytopathogenic bacteria and fungi is discussed.
