What kind of bacterium would be most likely found in the human stomach?

a. salt-loving

b. acid-loving

c. heat-loving

d. sulfur-loving

The bacterium we would most likely find in a human stomach would be probably an acid-loving bacterium - b.

The reason for this is simple - the human stomach is quite acidic which enables it to break down a lot of different substances that get carried into the body through digestion.

b. acid-loving

It would only make sense that the human stomach has the type of bacteria that is "acid-philic" or acid-loving since it is composed of the acidic composition which primarily does the second chemical breakdown of the food consumed.
