Ethanol fermentation by yeast is an important process in the manufacture of ethanol or alcohol and in the process of anaerobic respiration yeast produces ethanol. It is very important to restrict the presence of oxygen during the fermentation process so that the yeast can ferment sugars into ethanol or drinking alcohol as it is also known.
Every type of ethanol production including ethanol for human consumption and bio ethanol for powering engines needs to pass through the fermentation process that converts the mashed mixture of water along with various fruits or grains or vegetables into ethanol with the desired alcoholic strength. Once the mash is ready for sugar fermentation then dried yeast powder is added to the mixture to start the process of converting sugars present in the mixture into ethanol. However, during this process, it is very important to prevent oxygen from remaining present in the mixture since it is only in the absence of oxygen that yeast nutrient will switch over to anaerobic respiration where the sugars including glucose, fructose, sucrose, etc get converted into ethanol and carbon dioxide.
If oxygen is present during fermentation then instead of anaerobic respiration yeast will enter into aerobic respiration where the end result will simply produce carbon dioxide gas along with oxygen. One common example is baker’s yeast that is used to produce fluffy breads and cookies. On the other hand, when the mash is sealed in a vessel that does not allow entry of oxygen then the yeast is forced into anaerobic respiration where the end result is ethanol and carbon dioxide gas. During this process, one molecule of glucose is converted into two molecules of ethanol and two molecules of carbon dioxide.
There are various types of yeast that need to be utilized during the fermentation process based on the alcohol that is desired by the manufacturer. Although ordinary brewers yeast or distillers yeast can be used to produce alcoholic beverages, one form of hardy yeast that has excellent levels of alcohol tolerance as well as higher temperature tolerance is turbo yeast. This fortified yeast can produce stronger alcohol even at higher temperatures as well as produce larger quantities of alcohol even from weaker mashes. The end result is high levels of cost savings as well as freedom from the problem of stuck fermentation, which is every alcohol manufacturer’s nightmare.
These turbo yeasts are available on select websites and distillers that range from people making alcohol at home in home distilling kits to large producers that might have professional ethanol plants, can simply order for small sachets or bulk quantities with ease. This yeast is available under several variants such as turbo yeast 24, turbo yeast 48, etc that can be chosen by ethanol producers based on their choice. This sturdy yeast can improve production efficiency, provide for stronger alcohol concentration as well as lower costs at the same time.
It is very important to choose the right yeast as well as the right fermentation process to convert sugars present in the mash into the desired form of ethanol. Lack of oxygen during fermentation forces yeast to go into anaerobic respiration and in the process of anaerobic respiration yeast produces ethanol that can then be transformed into the required alcoholic beverage.
