Beschrijving
Media with Yeast Nitrogen Base without Amino Acids and Ammonium Sulfate are included in many applications for the study of yeasts in molecular genetics. Yeasts are unicellular, eukaryotic, budding cells that are generally round-to-oval or elongate in shape. They multiply principally by the production of blastoconidia (buds). Yeast colonies are moist and creamy or glabrous to membranous in texture. Yeasts are considered opportunistic pathogens.
