It dependes on where the bacteria are growing. You can use antibiotics if they are in your body. If they are on food the refrigeration, salting and pickling. You could also limit the food source avalible.
Kills it
The pickling process creates an acidic environment that is inhospitable to bacteria, slowing down their growth and spoilage of the onions. The addition of vinegar or other acidic ingredients lowers the pH of the solution, inhibiting microbial growth and extending the shelf life of the pickled onions. Additionally, the salt in the pickling solution helps draw out moisture from the onions, further inhibiting bacterial growth.
It creates an acidic environment which many bacteria cannot tolerate.
Capable of inhibiting the growth or reproduction of bacteria. Different from bactericidal (capable of killing bacteria outright).
Pickling food helps preserve it by creating an acidic environment, typically through the use of vinegar or fermentation, which inhibits the growth of spoilage-causing bacteria and molds. The process also often involves the addition of salt, which draws out moisture and further creates conditions unfavorable for microbial growth. Additionally, pickling can enhance the flavor and texture of foods, making them more enjoyable to eat while extending their shelf life.
Salt prevents the growth of bacteria.
The sound waves of the music could effect the growth of the bacteria.
Vinegar is usually used to pickle foodstuffs and it is the acidity of this medium which prevents the growth of spoilage bacteria. The vinegar can also be flavoured with various spices further enhance the taste of the pickle.
Iron helps fight the bacteria that grows in algae. It dosn't effect the plants.
Freezing conditions can inhibit the growth and reproduction of bacteria and fungi by slowing down their metabolic activities. However, some bacteria and fungi have adapted mechanisms to survive freezing conditions by producing antifreeze compounds or spores. When the temperature rises, these organisms can resume their growth and metabolism.
Acetinobacter aceti is the vinegar producing bacteria.
