Bakteerifaatioista, or bacterial fermentation, is a metabolic process in which bacteria convert organic compounds, primarily carbohydrates, into different products such as acids, gases, or alcohols. This process occurs in the absence of oxygen, making it an anaerobic form of metabolism. Bacterial fermentation plays a vital role in various natural and industrial systems, including nutrient cycling, food preservation, and biotechnology.

In nature, bacteria utilize fermentation to survive in environments where oxygen is scarce, such as soil, deep water, and the gastrointestinal tracts of animals. Certain species, like Lactobacillus and Bifidobacterium, are well-known for their fermentative abilities and are essential for maintaining healthy gut microbiota in humans and other animals. These bacteria contribute to digestion and produce beneficial compounds like lactic acid.

Industrially, bacterial fermentation is employed in the production of numerous products. Lactobacillus species are used in the fermentation of dairy products such as yogurt and cheese. Yeasts and bacteria facilitate the production of alcoholic beverages like beer and wine, as well as biofuels such as ethanol. Additionally, fermentation is utilized in the manufacturing of acids (e.g., acetic acid), enzymes, and pharmaceuticals.

The process involves enzymatic breakdown of complex molecules into simpler molecules that bacteria can metabolize. The end products of bacterial fermentation depend on the specific bacterial species and substrates involved. The method is valued for its efficiency, sustainability, and the ability to produce a wide range of useful compounds under mild conditions.

Bacterial fermentation continues to be a focus of scientific research, especially in developing sustainable industrial processes and understanding microbial roles in environmental and human health.
