Naganishia vishniacii
Species of fungus
Naganishia vishniacii is an extremophile fungus originally isolated as a yeast from soil samples in the dry valleys of Antarctica. The species grows at 4 degrees Celsius and below but not at 26 degrees Celsius and above. Visually it is characterized as a cream mass in culture. It is nonfermentative and assimilates glucose, maltose, melezitose, trehalose, and xylose.[1] Molecular research, based on cladistic analysis of DNA sequences, shows that the species does not belong in the Cryptococcaceae.[2] [3]
