4. Baker’s Yeast Sacharomyces cerevisiae Incredibly important to human civilization –Bread –Beer wine…

5. Baker’s Yeast Sacharomyces cerevisiae One of few single-celled fungi As they eat, they release two waste products: –Carbon dioxide (This is what caused bread to rise) –Alcohol when contained, this ferments beer and wine turning them into alcoholic beverages.

6. Baker’s Yeast Sacharomyces cerevisiae Reproduce by budding (asexual reproduction)

7. Baker’s Yeast Sacharomyces cerevisiae There is yeast in the air and this yeast will grow in most warm, moist environments.
