How does acid in the stomach kill bacteria?

Answer 1

The stomach acid makes the stomach a particularly hostile environment for bacteria. It is an too acidic an environment for most microorganisms to survive. In addition there are proteases that will digest most cells.

Answer 2

Quite simply, the bacteria are acid-stable which is to say, they can live just fine in a pH that low (about 2). Bacteria throughout the world have adapted biochemically in order to survive in various extreme environments such as the thermophiles in the springs at Yellowstone National Park.

Answer 3

The stomach contains a highly acidic mixture of enzymes, acids, etc. Specifically, the inside of the stomach is acidic to allow the enzyme pepsin to work at its maximum efficiency. The use of hydrochloric acid (HCl) acidifies to stomach juices to around a pH of 2. This highly acidic environment allows the destruction of bacteria. The acidic nature of the stomach contents can denature bacterial enzymes, DNA, etc. Therefore, I would say that the acidity of the stomach is what helps destroy bacteria, and prevent infections from said bacteria.

Answer 4

By creating a pH which is too low (acidic) for many microorganisms to survive.

Answer 5

may be yes
