It depends on what is fermenting. Cow poo, produces methane. Fruits produce alcohol.

Fermentation
gas (CO2) generated by bacterial fermentation of lactose in the left over milk film.
Fermentation is a metabolic by which sugars turn to acids, gases, or alcohol using yeast or bacteria. The sugar molecules break down, and the energy generated from that reaction enable the other molecules to bind to new molecules, which creates the acids, gases, or alcohols depending on what the surrounding molecules are.
Anaerobic respiration-this respiration takes place without oxygen. In the case of anaerobic respiration, glucose is broken and the products generated from this are energy and either lactic acid or ethanol (alcohol) and CO2. This process is termed as fermentation.
Alchoholic fermentation and Lactic Acid fermentation
in the biostil fermentation the fermentation and distillation are coupled.
Pyruvate and NADH because of the different strains and ways of metabolic , the products generated by different sorts are not same in which lactic acid fermentation is divided into 3 types ,the same type of lactic acid fermentation ,abnormal fermentation of lactic acid and bifidobecterium fermentation
There are different kinds of fermentation, and fermentation can be aerobic, or anaerobic.
This is called the glycolysis pathway. It begins with glucose and ends with pyruvate before entering the Krebs cycle where ATP (adenosine triphosphate) is generated for energy.
