Basically, bacteria (usually called yeast) feed on sugars turning them into alcohol.
Sugar fermentation is a metabolic process where sugar molecules are broken down by microorganisms such as yeast or bacteria in the absence of oxygen to produce energy. This process typically results in the formation of alcohol and carbon dioxide as byproducts. Sugar fermentation is commonly used in food production, such as in the making of bread, beer, and wine.
Fermentation is a process that converts sugar to acids, gases or alcohol. In yeast the fermentation process is carried our in beers, wines and other alcohol.
to explain how things happen
fermentation, chemical process by which molecules such as glucose are broken down anaerobically. More broadly, fermentation is the foaming that occurs during the manufacture of wine and beer,
The process of fermentation releases carbon dioxide, so we can not stay in fermentation forever.
Fermentation is the process by which microbes transform one substance into another. Fermentation is the process for making both bread and beer.
while respiration implies air, fermentation is an anaerobic (no oxygen) process.
The anaerobic process
Fermentation
Fermentation can technically be considered an old life process. This is because fermentation takes quite a while to take place.
I assume you meant respiration - in which case : fermentation does not require oxygen.
Single fermentation typically refers to a process where fermentation occurs only once, instead of multiple stages like in some traditional fermentation methods. This process is commonly used in beverage and food production to simplify the fermentation process and can result in a quicker production time.
