Turns out, thiobacteria have settled on my car, they lived happily ever after, and in the process of their life they secrete organic and non-organic acids, alkalis, ammonia and other substances that initiate and intensify the corrosion reaction (destruction of the metal). If you clean up all the products of their life, will the car stop to fail, thought I. As it turns out, no it isn’t. These bacteria can breathe by destroying metal while extracting energy for life.
