Patient's question:
I saw a creature called yeast. Since she is young and doesn't understand, she came to ask me. But I don't understand either, so I want to ask what yeast is, and also ask if yeast is a fungus?Doctor's answer:
As early as 3,000 years ago, humans began to use yeast to produce fermented products. The first product sold in the market was yeast slurry, which was characterized by fast fermentation but inconvenient transportation and use, limiting its commercialization. From the sale of yeast slurry, if we consider the production of yeast as an industry, the history of the yeast industry has already spanned over 200 years. Yeast has become one of the most studied microorganisms in the world, serving as a hot spot for the research and development of modern biotechnology products and a model system for the advancement of modern biotechnology and genomics research.
