Alcohol arguably the most important part of wine production and is the result of anaerobic respiration/ fermentation. Aerobic respiration results in vinegar.
When yeast is added to a sugary mixture (such as wort) the by-products are Carbon Dioxide and alcohol. This is the most evident in the fermentation process of beer brewing or the making of wine.
yeast excrete CO2 after they undergo respiration.
-- carbon dioxide
-- alcohol, if not attended to
-- spores to make more yeast, if properly cared for
Carbon dioxide
Carbon dioxide.
Alcohol
Fermentation.
Yeast eating sugars and excreting waste. Alcohol is yeast waste.
When yeast cells ferment it builds up gases. That is the reason why champagne might explode from the bottle just after opening. It is also why there is a distinct popping noise when wine is opened.
Alcohol and carbon dioxide are two waste products that are given off by a fermenting yeast.
Yeast cannot produce their own foods. The yeast do not have chlorophyll. Yeast must rely on other ways and sources to get food. Yeast mostly feed on sugar.
No Yeast cells produce spores which serve the same function as seeds
Yeast can produce more that 30 o/o or more
These yeast cultures produce uniform, predictable results
the waste that the cell produce is protiens.
Yeast cells are facultatively anaerobic. This means that they perform fermentation under anaerobic conditions. When the oxygen concentration is low, pyruvate is turned into ethanol and carbon dioxide.
