Draft genome sequence of three Glaciozyma watsonii strains isolated from near the Syowa station area, East Antarctica

mycolabadmin

Scientists have sequenced the genetic code of three strains of a special cold-loving yeast called Glaciozyma watsonii found in East Antarctica. This yeast can grow in extremely cold conditions, even at temperatures below freezing, which is remarkable. Understanding its genome may help scientists develop new medicines and discover enzymes that work in cold conditions.

Contrasting stability of fungal and bacterial communities during long-term decomposition of fungal necromass in Arctic tundra

mycolabadmin

Scientists studied how dead fungal material breaks down in Arctic soil over three years. They found that melanized fungi, especially Pseudogymnoascus, are key decomposers that help break down tough fungal material containing melanin. While bacterial diversity increased over time, the fungal community remained relatively stable. Even after three years, about 20% of the fungal material remained undecomposed, suggesting it can help store carbon in Arctic soils.
