Some microorganisms such as yeast produce energy in oxygen-free environments through anaerobic cellular respiration. Anaerobic cellular respiration is where oxygen is not used. Yeast produces energy by converting sugars into alcohol, gas or acetic acid. <span>This process is called fermentation. </span>Ethanol is a by-product of fermentation. Humans have used fermentation to produce food and drink since the Neolithic Age. Fermentation makes yoghurt from milk by producing lactic acid.
