Peculiarities of the growth of a dark pigmented yeast-like fungus, Pseudonadsoniella brunnea, on 32 nutrient media (11 solid, 3 semisolid and 18 liquid ones) are characterized. The most optimal media for this fungus found to be Saburo agar, Saburo agar with 10 % sucrose solution, original medium with rolled oats, bran and 10 % sucrose solution, pieces of raw potato with and without 10 % sucrose solution, modified glucose peptone-yeast medium, peptone water with glucose, beef-extract [meat infusion] broth with glucose and gelatin. Acidic media (pH = 3–4) are the most optimal for P. brunnea growth.

Keywords: Antarctic, yeast-like fungus, optimal nutrient media
