High mycolic acid of certain bacterial cell wall
Acid in the stomach is a primary bodily defense against microorganisms. Obviously, it can be overwhelmed or bypassed, but it is toxic to many microorganisms.
An amino acid is just a molecule that is a building block of proteins. They are not living and they aren't microorganisms.
you get sick
it has a mild acid wich would kill them

Dye and nitric acid are different. A dye is a colored substance that has an affinity to the substrate to which it is being applied. The dye is generally applied in an aqueous solution, and requires a mordant to improve the fastness of the dye on the fiber.
Yes, the microorganisms produce lactic acid. Milk curdles in the presence of an acid.
Im not really all that sure but I have reason to belive either acetic acid in wine or yeast in bread is made up of microorganisms.
Acid mine drainage is the low pH created by microorganisms convering sulfides and sulfates in tailing from the ore processing into sulfuric acid.
No, the juice has high levels of citric acid which makes pH for acid higher and thus unsuitable for microorganisms to grow.
Hydrochloric acid reduces the pH of the stomach fluids to 1.5-2. At such a low pH, most microorganisms are unable to survive. So, when we ingest microorganisms with our food, they are killed by the acidic conditions in our stomach. That is why, people don't fall sick all the time.
