Yeast vs. Molds: What's the Difference?
Yeast is a unicellular fungus used in fermentation, while molds are multicellular fungi that grow in filamentous structures.
Yeast are unicellular fungi, often used in baking and brewing due to their fermentation capabilities. Molds, in contrast, are multicellular fungi, known for their filamentous growth and often found on spoiled food.
In yeast, the primary method of reproduction is budding, where a new cell grows out of the parent cell. Molds reproduce through spores, which can spread and grow into new mold colonies.
Yeast cells are generally oval or spherical in shape. Molds, however, form long, thread-like structures called hyphae, which intertwine to form a mycelium.
Yeast plays a beneficial role in food production, like in bread making, where it causes dough to rise. Molds are usually undesirable in food, causing spoilage, though some are used in cheese making.
Yeast typically thrives in moist, warm environments, useful in controlled fermentation processes. Molds can grow in various conditions, often appearing in damp, humid areas.
