Species composition of micromycetes at the Progress, Vechernyaya Gora, and Novolazorevskaya stations (East Antarctica)

The survival of fungi in Antarctica is a consequence both ecological selection and evolutionary adaptation expressed at the physiological, metabolic, structural, genetic levels. study biological diversity Antarctic micromycetes will help us to better understand pathways fungal dispersal biosphere, as well broaden our understanding their role extreme ecosystems. In addition, habitats are promising objects biotechnology. purpose work microscopic on natural anthropogenically introduced substrates East Antartica research areas Progress, Novolazarevskaya, Mount Vechernyaya stations. Traditional isolation methods were used isolate culture. To determine species composition, microbiological molecular used. As result mycological analysis, 46 from 22 genera 3 phylum identified. taxonomic analysis was made dominant identified: Thelebolus, Penicillium, Acremonium, Aspergillus, Cladosporium, Geomyces, Cadophora, Rhodotorula, Cryptococcus. temperature-dependent growth features analyzed: most isolated psychrotrophic. greatest noted soils with plant animal inclusions, smallest – stony substrates.
