Kirtsideli, Irina Y. Iliushin, Vadim Arctic coal mine microfungi spoil tips thermophilic thermotolerant Ártico microhongos mina de carbón termófilo termotolerante vertedero de carbón Background and aims: Thermophilic and thermotolerant fungi occupy a variety of ecological niches. The purpose of this article is to show that these microfungi are able to live even in such harsh conditions of the high Arctic beyond the Arctic Circle. M&M: Rock from coal mine spoil tips were collected and studied using scanning electron microscopy. The method of direct inoculation was employed to isolate microfungi. The isolates were identified using morphological identification and molecular methods. The growth rate of micromycetes was studied depending on temperature. Results: Eight cultures of microfungi belonging to six species that are able to grow at temperatures of 45 °C and above were isolated from coal mine spoil tips. Conclusions: The data obtained indicate the presence of thermophilic and thermotolerant microfungi in the spoil tips of coal mines beyond the Arctic Circle. All the fungi belonged to the order Eurotiales. These microfungi are able to exist in the harshest conditions with several simultaneous adverse factors. Introducción y objetivos: Los hongos termófilos y termotolerantes ocupan una variedad de nichos ecológicos. El objetivo de este artículo es mostrar que estos hongos microscópicos son capaces de vivir incluso en las duras condiciones del alto Ártico más allá del Círculo Polar Ártico. M&M: Se recogieron y estudiaron rocas de los restos de las minas de carbón mediante microscopía electrónica de barrido. Se empleó el método de inoculación directa para aislar microhongos. Los aislamientos fueron caracterizados mediante identificación morfológica y métodos moleculares. La tasa de crecimiento de los micromicetos se estudió en función de la temperatura. Resultados: Se lograron ocho cultivos de hongos microscópicos pertenecientes a seis especies que pueden crecer a temperaturas de 45 °C y superiores de los escombros de las minas de carbón. Conclusiones: Los datos obtenidos indican la presencia de hongos microscópicos termófilos y termotolerantes en los vertederos de minas de carbón más allá del Círculo Polar Ártico. Todos los hongos pertenecían al orden Eurotiales. Estos hongos microscópicos pueden existir en las condiciones más duras con varios factores adversos simultáneos.
