Nutritional physiology and selective isolation of Exophiala dermatitidis.
The nutritional physiology of ten strains of Exophiala dermatitidis was investigated. The growth reactions to lactose, citrate, nitrate, nitrite, lysine, creatine and creatinine differ from those found in closely related black yeasts. In addition, it is the only Exophiala species which is able to grow at 40 degrees C. A selective medium containing meso-erythritol as sole carbon source was evaluated. This medium is particularly useful for the isolation of black yeasts from lungs of patients with cystic fibrosis as well as from the environment.
