Difference Between Molds And Yeasts
Last Updated :
15 May, 2023
Moulds and yeasts differ in that molds develop in multicellular filaments whereas yeasts grow as a single cell. Both yeast and molds are eukaryotes with cell nuclei and membrane-bound organelles in the kingdom of Fungi. They can reproduce either sexually or asexually. Yeast, on the other hand, is unicellular and can be spherical, oval, or filamentous. The most common method of asexual reproduction in yeasts is budding.
Molds
Mold is a type of fungus that arises in the form of hyphae, which are multicellular threads & colonies that can be seen with the naked eye. It is a multicellular organism and threadlike fungus. The growth of molds in the form of multiple tubular branches. Found in humid areas, damp areas, dark areas, etc. It may be orange, green, pink, brown, purple, etc. It takes more time than yeasts to grow.
Examples: Some common examples of molds include Penicillium, Aspergillus, and Rhizopus.
Yeasts
Yeast is a microscopic fungus that is made up of a single oval cell and has a one-celled organism. Yeast is oval-shaped as well as colourless or we can say white in appearance. It is a unicellular organism and budding fungus. The growth of yeasts in the form of large single cells. It is colourless as compared to molds.
Examples: Some examples of yeasts include Saccharomyces, Candida, and Cryptococcus.

Conclusion
In conclusion, molds and yeasts are two different types of fungi with distinct characteristics. Molds are multicellular and filamentous, whereas yeasts are unicellular and typically spherical or oval-shaped. Molds can thrive in diverse environments and can cause health problems in humans and animals, while yeasts require specific temperatures and pH for growth and can cause infections. Both molds and yeasts can be used in various industrial applications, such as food and beverage production. It’s essential to understand the differences between molds and yeasts to identify and control them effectively.
