Table salt, which consists primarily of sodium chloride, is the most important ingredient for curing food and is used in relatively large quantities. Salt kills and inhibits the growth of microorganisms by drawing water out of the cells of both microbe and food alike through osmosis. Concentrations of salt up to 20% are required to kill most species of unwanted bacteria.
Once properly salted, the food's interior contains enough salt to exert osmotic pressures that prevent or retard the growth of many undesirable microbes.

How do you Kill Halophilic Bacteria?
with salt
Explain what happens to meat when it is packed in salt?
When the meat is packed in salt it will last longer because the salt prevents the meat from growing bacteria or mold and spoiling. The meat will last for a year or so.
What percent of bacteria will water kill?
What percentage of salt mixed in water kills bacteria
Give the example of food preservation?
Pour Salt, kill the air Decrease bacteria Pour Salt, kill the air Decrease bacteria
Why does salt kill bacteria?
If it doesn't kill the bacteria, it at least disables it and prevents it from growing; salt water is hypertonic to the bacteria, i.e. there's greater concentration of solute (salt) outside the cell than inside. When exposed to this, the water inside the bacteria will essentially be sucked out, leaving the bacteria dead, or disabled. Some bacteria, such as the ones that cause a sore throat, can be tackled this way. Others can cope with salty environments, so salt isn't a universal antibacterial substance.

What happens to meat when its packed in salt?
drys/preserves meat. (kills bacteria)
Will slow cooking meat cook out all of the bacteria on questionable meat?
It will kill a lot of bacteria, but it does not sterilize the food.

How do you preserve meat using salt in a hot humid climate?
You would salt the meat sufficient to dry it out - in very hot and/or humid climates you would almost have to pack the meat into a case of salt to get the proper dehydration. The salt reduces the water activity (basically the amount of water available to bacteria) in the meat - if the water activity is too low bacteria can't grow and therefore can't spoil the meat.
Why doesnt salted meat rot?
Salt will drain the meat of its water and dehydrates it. Salt has lower water potential then the water in the cell sap of the meat and water will move out of the meat through diffusion. Thus without water, no bacteria can grow on the meat because of the need for water for all living organisms.
Can Hepatitis A survive in salt water?
Yes, salt water is not corrosive enough to kill bacteria.

What can salt kill or clean?
both actually, salt can kill slugs and can clean your thruoght like if you have soar thruoght than you can gargle salt water and can clean out the bacteria
Why salt is important in salt gargle?
That is because of osmosis . To kill the bacteria we need it . It also loosens mucus
How did using salt to preserve meat keep microorganism off?
Salt absorb water and kill microorganisms.
