What will happen to organisms in a hay infusion culture when conditions are acidic?
Bacteria die at acidic conditions but some has a specific pH to be eradicated. Since we are dealing with unknown specimen of bacteria, we can hypothesize that no, or some, bacteria will survive the condition. (Sorry for my english.)
Why conditions in the stomach are acidic?
The stomach is acidic because the stomach lining produces gastric acid. This helps the body start to digest proteins as well as provides a protective barrier against most bacteria and viruses.
How does acid in the stomach kill bacteria?
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.
What are conditions like in the stomach?
the stomach hold an acid which is very acidic
What dangers do high level nitrates in the drinking water present for infants?
Humans and other animals usually have bacteria that convert nitrates into nitrates in their large intestines. For adults, the presence of these bacteria in the digestive system is not harmful, because the stomach of an adult is so acidic that the bacteria cannot survive. But the stomach of an infant is much less acidic, so the bacteria can move up into the stomach, where they will convert nitrates into nitrites. The nitrites can then pass into the blood of the infant.

Why does the stomach contain HCl?
HCl lowers the pH in the stomach and provides the acidic conditions for the digestive enzymes in the stomach to work effectively.
What types of bacteria are found in harsh or extreme conditions?
Bacteria that can thrive in harsh or extreme conditions are often categorized as extremophiles. These include thermophiles that live in high temperatures, psychrophiles in cold temperatures, acidophiles in acidic environments, alkaliphiles in alkaline environments, and halophiles in high-salt environments. These bacteria have developed specialized adaptations that allow them to survive and function in such challenging conditions.
How does pH 3 benefit the working stomach?
It's very acidic so it will provide the conditions for enzymes to multiply and it will kill off bacteria. Acid DOES NOT digest the food, ENZYMES digest the food
In what level of acidity does bacteria grow?
Prokaryotes (including bacteria) are the most diverse kingdom on earth. Bacteria are able to survive and thrive at a variety everyone on this earth. In acidic, boiling, freezing, basic, little water, high radiation environments there is a bacteria that can survive.
How do you remove stomach bacteria?
Stomach bacteria is naturally neutralized with acidic or certain compounds in foods. If you drink lemon juice or orange juice, the bacteria will be suppressed. Also, compounds found in chili peppers are known to kill any bad bacteria.
What is the benefit of having hydrochloric acid in your stomach?
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.
