Saccharomyces cerevisiae

Saccharomyces cerevisiae or as we know it, active dry yeast is best cultivated at 30-35°C. It is unicellular and about 5–10 μm in diameter. It reproduces by an asexual process known as budding which takes 2 hours. This is not an airborne fungi it's spread to new places my animal contact . It has the amazing ability to double its population every 100 minutes. Its granulated form was developed during World War II when there was a shortage of yeast to cook with. This allowed yeast to have a shelf life and not spoil as fast. Soon after they developed ones that could last 2 years. A centrifuge is used to get only Saccharomyces cerevisiae to reproduce funneling out the other types of yeast under the microscope until only this strain could survive and the others were outcompeted. It is also the only yeast cell known to have Berkeley bodies present, which are involved in secretory pathways. Interestingly enough antibodies to it are found in 60–70% of patients with Crohn's disease and 10–15% of patients with ulcerative colitis. Seen at 30.1 regular light microscope with sucrose soln
