Four samples of surface soils, one with shoots of an unidentified moss species, were collected from a geothermal site on the northwest slope of volcanic Mt. Melbourne (northern Victoria Land, continental Antarctica) to determine physico-chemical properties, isolate existing strains of heterotrophic microorganisms, and identify the moss species through molecular genetic techniques. Surface soil features such as temperature, grain-size, pH, moisture content, and isolated genera of bacteria…
