Basidiomycetous Yeast of the Genus Mrakia
Basidiomycetous yeast species of the genus Mrakia have been reported from a variety of extreme cold environments such as polar regions, glaciers, and high mountains. Several reports indicate that fungal species within the genus Mrakia occupy a major mycoflora in Antarctic environments. These results strongly suggest that this genus is well adapted to the polar environment. The genus Mrakia has unique characteristics such as an ethanol fermentation ability, and the ability to decompose milk fat under low-temperature conditions. Thus, the genus Mrakia has quite interesting characteristics. We believe that the results obtained in previous studies will contribute to the progress of related research fields and hope that further investigation will offer many opportunities to obtain more valuable knowledge on Antarctic microbes and their potential uses for human activities. In this chapter, we review the taxonomic history, physiology, ecological role, and biotechnological applications of basidiomycetous yeasts within the genus Mrakia. In the near future, this genus will become an important agent in the field of low-temperature microbiology.
