English name: yeast

Yeast is some unicellular fungi, not a unit of phylogenetic classification. Yeast is the earliest microorganism used in the history of human civilization. At present, there are more than 1000 kinds of yeast. According to the ability to produce spores (ascospores and basidiospores), yeast can be divided into three types: the strains that form spores belong to ascomycetes and basidiomycetes. Those fungi that do not form spores but propagate mainly through budding are called incomplete fungi, or "false yeasts". At present, it is known that most yeasts are classified as Ascomycetes. Yeast is widely distributed in nature, mainly growing in acidic and humid sugary environments. For example, it is most common in fruits, vegetables, preserves and orchard soil.
