Which Microorganisms Ferment Glucose Produce?

Fermentation is a biological process carried out in the absence of oxygen wherein energy is generated from organic compounds. Of the different types of fermentation, fermentation of glucose is one of the more general where through metabolic reactions, glucose can be broken down into some simpler compounds. Many microbes can ferment glucose, which results in the production of different end products depending upon the type of fermentation pathway that occurs.

Overview of Organisms that Ferment Glucose

The list of microorganisms that ferment glucose is very long and comprises bacteria, yeast, and even fungi. Among bacteria, glucose can be fermented by Escherichia coli, Bacillus, Clostridium, Streptococcus, and Lactobacillus. The same goes for yeast, including Saccharomyces cerevisiae and Candida albicans, and the fungi Aspergillus and Penicillium.

Identifying the Microorganisms That Fuel Fermentation

Microorganisms’ discovery that ferment dates way back to the 19th century when Louis Pasteur first identified the role of yeast in alcoholic fermentation. Since then, so many other microorganisms were identified as being involved with different types of fermentation: glucose fermentation. Improved methodologies like DNA sequencing, metabolic profiling have aided in the establishment of identification of such kinds of organisms in terms of the particular genes and type of enzymes responsible for other processes of fermentation.

Perspective view of Various Types of Fermenters

There are different kinds of fermenters through which glucose can be ferments to give various kinds of end products. Lactic acid fermentation is one of the most common types of fermentation and is carried out by such bacteria as Lactobacillus and Streptococcus. This fermentation takes glucose and changes it into lactic acid for yogurt and cheese, amongst others. The fermentation of glucose to ethanol is another type of glucose fermentation carried out by yeast like Saccharomyces cerevisiae.

Conclusion

Glucose fermentation is one of the biological processes that are carried out by several microbes including bacteria, yeast, and fungi. The various end products of glucose fermentation include lactic acid, ethanol, and acetic acid. The identification of new microorganisms and efficient fermentation processes are very much in demand for further development in industries that depend upon glucose fermentation. Along with further research into the metabolic pathways and genetics of these glucose-fermenting organisms, so will go on the areas of applications of this essential biological process.
