In alcoholic fermentation, the initial process is the breakdown of glucose. The cell breaks down glucose to produce energy in the absence of oxygen. The process is called glycolysis and takes place in the cytosol of the cell.The energy released from this reaction is useful in the conversion of NAD+ to NADH. The energy is also used in binding ADP to inorganic phosphates. Production of two pyruvate molecules follows. Breakdown of the two pyruvate molecules takes place leading to the production of two acetaldehydes and two CO2 as a waste product. It then follows that the two acetaldehydes undergo the conversion to two ethanol using the H+ ions from NADH, which is converted back to NAD+.Alcoholic fermentation has many applications. Some of these applications are the production of ethanol fuel, in bread baking, in the fermentation of foods such as milk and vegetables and the production of alcoholic beverages such as wine and beer. Despite the fact that the general principle of fermentation is the same for all products, the method of achieving it and the end results differ. Beer preparation by fermentation involves picking rye, wheat or barley followed by germinating, drying and pulping it into a mash. The mash is mixed together with hot water and transferred to a fermentation vessel to commence the process of fermentation. Yeast is added to the mixture that converts the sugar present in the ash to carbon dioxide and alcohol. Once the beer is filtered and conditioned, it is ready for consumption.

Culturing was both on agar and broth media incubated at 37 o c and 25 o c. The biochemical tests were: Glucose fermentation, sucrose fermentation, Lactose fermentation, Maltose fermentation, Starch hydrolysis, Citrate utilization, Catalase test, Tryptophan digestion (Indole).The most probable bacteria were Bacillus spp which includes C.Tetani, C.
From this research, it is clear that respiration processes and fermentation processes are similar in that both have carbon dioxide involved in the processes. In the respiration process, the carbon dioxide is the respired gas. In the fermentation process involving glucose carbon dioxide is the byproduct of the reaction that mainly results in the conversion of glucose into ethanol.
Fermentation is the process in which carbohydrates are converted into alcohols under anaerobic conditions with the aid of yeasts and bacteria or a combination of both with the concomitant production of carbon
A deionized water blank is run and the results of the sample titration and blank are compared.
5. The winemaker might want to know the amount of sugar remaining in wine as it nears the fermentation process
Through this study, we can observe the amazing reactions. The unknown microorganism was able to ferment sucrose anaerobically hence the production of carbon dioxide and the color change. From the obtained results, the identity of the unknown microorganism was the bacterium Proteus vulgaris.
In the first part, fermentation is measured using gas height as proxy for carbon dioxide measure and the rate of reaction. In the second part, respiration is measured in terms of carbonic acid production. (ASPB Foundation n.d.; Nuffield Foundation 2013; The Regents of the
The word Fermentation is derived from Latin verb “fever” which means “to boil”. It is the process through which energy is derived from the oxidation of organic compounds such as carbohydrates, by using an electron accepter, usually an inner organic compound.
