Yeast is a type of microorganisms that is a group of single-celled fungi. As fungi, they are the most well known among people, including:

  • Baker’s yeast,
  • The molds that ripen blue cheese,
  • The molds that produce antibiotics for medical use,

Under the monocle of the microscope, yeast cells appear in the shape of an egg and they cannot be seen only under the microscope because 20,000,000,000 (twenty billion) yeast cells weigh one gram!

The scientific name for it is Saccharomyces Cerevisiae, or “sugar-eating fungus”. A very long name for such a tiny organism! But this tiny organism has many nutritional and cosmetic benefits.
