BIO 2071 Assignment Mold and Yeast Comparison Template
There are 1500 types of yeast present; they are used in industry for the baking purpose, additive, in alcohol production, food beverages. Yeast is very common and can be found in fruits, vegetables, on the skin of mammals and among other places.
Whereas, there are around 400,000 types of molds found. They are also used in industry for cheese making and another process. Though molds can be sometimes hazardous also by causing respiratory infections and allergies. Molds are usually found in damp, dark or steam-filled areas.
Yeast and Molds are microorganisms, but both are Eukaryotes and belongs to the kingdom fungus. Eukaryotes are known for having well-defined nucleus along with other cell organelles with specific functions. Being of the same kingdom, both differ in function, appearance, colour, and mode of reproduction.
Content: Yeast Vs Mold
| BASIS FOR COMPARISON | YEAST | MOLD |
|---|---|---|
| Meaning | Yeast is a type of single cell microorganism, falls under kingdom fungi. | Molds are multicellular microorganisms, usually colorful and also fall under kingdom fungi which grow in a multicellular filaments called hyphae. |
| Kind of cell | Single cell. | Multicellular. |
| Shape | Filamentous or Threadlike. | Round or oval. |
| Presence of Hyphae | Pseudo-hyphae i.e. they don’t have true hyphae. | Hyphae (microscopic filaments). |
| Presence of Spores | Non-Sporous fungi. | Sporous fungi. |
| Types | There are 1500 types of yeast. | There are 400,000 types of molds. |
| Mode of Reproduction | Asexual through mitosis. Common method is budding and spores formations. | Sexual or asexual. |
| Colour | Colourless and smooth (usually white). | Colourful, wooly and fuzzy (green, orange, black, brown, pink, purple). |
| Aerobic/Anaerobic | Yeast can grow in aerobic as well as in anaerobic conditions. | Mold grow only in aerobic conditions. |
| Uses | Yeast is used in beverages production like alcohol and also in making of baking, bioremediation, food additive. | Useful in biodegradation, food production (cheese), in making antibiotics. |
| Health Hazards | Yeast may weaken the immune system of the body and may contribute in asthma, crohn’s disease. | Molds may cause allergies, respiratory problems. |
| Examples | Saccharomyces cerevisiae (baking yeast), Cryptococcus neoformans, etc. | Mucor, Penicillium, Rhizopus, Aspergillus, etc. |
Definition of Yeast
Yeast is the single cell microorganisms considered as eukaryotes and so have a well-defined nucleus and other organelles. Though they reproduce asexually by binary fission or budding method where nucleus splits in two and daughter nucleus moves into the bud.
