Powdered Yeast Extract Powder 500g 1kg Brewers

Yeast is a unicellular fungus and not a unit of phylogenetic classification. A tiny single-celled microorganism invisible to the naked eye, which can ferment sugar into alcohol and carbon dioxide. It is distributed throughout nature. It is a typical heterotrophic facultative anaerobic microorganism that can survive under both aerobic and anaerobic conditions. It is a natural leavening agent. It generally refers to various single-cell fungi that can ferment sugars, which can be used in brewing production, and can also be pathogenic bacteria—model organisms for genetic engineering and cell cycle research. Yeast is the earliest microorganism used in the history of human civilization. More than 1,000 species of yeast are known, and yeast can be divided into three groups according to their ability to produce spores (ascospores and basidiospores): The spore-forming strains belong to the Ascomycetes and Basidiomycetes. Fungi that do not form spores but reproduce mainly by budding are called incomplete fungi, or "pseudoyeasts" (like yeasts).
