CH 4 Production: Aerobic fermentation: Aerobic fermentation does not produce CH 4 . Glucose can still be broken down in the absence of oxygen in order to meet the cells' energy requirements. In the beginning of fermentation the juice will be dominated by many different yeast strains of Hanseniaspora, Kloeckera, Pichia and many others – then as the alcohol increases different strains of Saccharomyces and Candida will take over because of … The process can be simply explained with the help of the following equation: Glucose + Oxygen → Carbon dioxide + Water + Energy.     Lactic Acid Fermentation.     La fermentation alcoolique a lieu grâce aux levures transformant le glucose en alcool. In the case of milk, when good healthy bacteria, such as Lactobacillus delbrueckii bulgaricus and Streptococcus salivarius thermophilus, are added and a particular temperature is reached, they start to nibble at the tasty molecules of lactose, which is a sugar, transforming them into pyruvic acid. FERMENTATION : The resulting solution is received in a large tank and yeast is added to it at 30 O C and kept for 2 to 3 days. A SECOND FERMENTATION is sometimes recommended to produce a clear beer, free of sediment, making a better beer, refining and polishing the taste.

Now to balance the oxygen atoms we require a coefficient 2 in front of carbon dioxide. It is important to make sure most of the yeast have been consumed but CO2 is still being, normally more slowly generated. Reasons to go further and convert lactic acid into something else include: The acidity of lactic acid impedes biological processes. If air is present, ethanoic acid is made instead of ethanol. In the 1850s and 1860s, Louis Pasteur became the first zymurgist or scientist to study fermentation when he demonstrated fermentation was caused by living cells. glucose ethanol + carbon dioxide C 6 H 12 O 6 (aq) 2C 2 H 5 OH (aq) + 2CO 2(g) The carbon dioxide gas bubbles out of the solution into the air leaving a mixture of ethanol and water.
