Light micrograph of dividing cells of the yeast species Hanseniaspora nodinigri. Yeasts are unicellular fungi of great economic importance because of their role in the brewing & baking industries, which depends on their capacity to secrete enzymes that convert sugars into alcohol & carbon dioxide; in baking, carbon dioxide causes the dough to rise. Yeasts are also exploited commercially as a source of proteins & vitamins. Magnification: X 380 for 35mm size, X 760 for 6x7cm.
