What are Yeast and Mold?
In this section, we will take a closer look at what yeast and mold are. These microorganisms are members of the fungi kingdom, which also includes mushrooms and mold-like species, such as mildew. Yeast and mold are unicellular and multicellular organisms, respectively, and can be found almost everywhere, from the soil to the air and water.
Yeast and mold have different physical attributes. Yeast cells are spherical or ellipsoidal in shape and usually measure between 3-40 micrometers, while mold cells have a branching, filamentous structure known as hyphae, which can extend several centimeters in length. Mold spores, which are reproductive structures, can range in size from 2-100 micrometers.
Yeast and mold are both capable of growing and spreading rapidly under favorable conditions. Yeast cells reproduce by budding, which involves the formation of a small outgrowth on the parent cell that eventually separates to form a new cell. Mold, on the other hand, produces spores that can be dispersed by air or water, allowing them to colonize new environments. Both yeast and mold require moisture and a source of organic matter to thrive, and can commonly be found in areas of high humidity or with poor ventilation.
