Yeasts are microscopic fungi capable of fermenting different carbohydrates.
In the process, carbon dioxide and ethyl alcohol are given off. Various industries, including the baking and brewing industries depend on selected yeast strains to add flavors, odors, and carbonation to their products. Most yeasts reproduce asexually by budding, a process which involves the equal splitting of an organism's nucleus, but an unequal division of its cytoplasm. The fermentative and microscopic features of the yeast Saccharomyces cerevisiae will be demonstrated in this exercise. Remove the top and place a balloon over the top of each tube.
