Can bacteria grow better in salt water or fresh water?
It really depends on the type of bacteria and the temperature of the water. Most species that prefer to live in a human's blood stream will like salt water over fresh. It is a lot more similar in chemical composition. But there are hundreds of water born disease that humans get from drinking contaminated fresh water. Most of these are also bacteria.
Reply:Bacteria grow better in salt water as fresh water is too clean for bacteria to grow.
Reply:They probably have their preferences.
Some may not thrive in salt water and another in fresh.
