Hi everybody,
There are numerous studies about the impact of pH changes on microbial growth. But, I am wondering to know if microbial growth (in the soil, water, etc.) is able to change the pH of the environment?
Thanks
While bacteria cause alterations in the pH of foods, such as milk/yogurt/saurkraut, but they also affect any environments while they grow. An example to check out is Article Modifying and reacting to the environmental pH can drive bac...
I would recommend a scholar.google search to find other articles.
Many thanks, Mr. John Wolff for your response! The paper you introduced is the most relevant paper I have found so far on google, but I will try to find more relevant sources!
Sincerely,
There are many bacterial strains that are capable of producing organic acids. The production of organic acids leads to decrease the pH of the medium. For example in food industry, lactic acid bacteria produce lactic acid and acetic acid leading to transform milk (pH about 6.2) to yogurt (pH about 4.6). In the pickling production, the lactic acid bacteria transform the sugars in vegetable medium (pH about 6-7) to lactic and acetic acids in pickled products (pH about 3.5 to 4.5). Another example,
Acetobacter oxidize ethanol to acetic acid in the process of vinegar production.
