Cell response of Antarctic strain Penicillium griseofulvum against low temperature stress
Duringthe evolution organisms are subjected to the continuous impact of environmental factors. In recent years an increasing number of studies have focused on the physicochemical limits of lifeon Earthsuch as temperature, pressure, drought, salt content, pH, heavy metals, etc. Extreme environmental...

Duringthe evolution organisms are subjected to the continuous impact of environmental factors. In recent years an increasing number of studies have focused on the physicochemical limits of lifeon Earthsuch as temperature, pressure, drought, salt content, pH, heavy metals, etc. Extreme environmental conditions disrupt the most important interactions that support the function and structure of biomolecules.Forthis reason,organisms inhabiting extreme habitats have recently become of particularlygreat interest. Although filamentous fungi are an important partof the polar ecosystem, information about their distribution and diversity, as well as their adaptation mechanisms, is insufficient. In the present study,the fungal strain Penicillium griseofulvum isolated from an Antarctic soil sample was used as a study model.
