There are exceptions: some bacteria thrive in extreme heat or cold.

some can survive under highly acidic or extremely salty conditions..

Why is temperature important for bacterial growth?

Generally,an increase in temperature will increase enzyme activity. But if temperatures get too high, enzyme activity will diminish and the protein (the enzyme) will denature. … Every bacterial species has specific growth temperature requirements which is largely determined by the temperature requirements of its enzymes.

Why are hospitals so cold?

Bacteria thrive in warm environments, so hospitals combat this with cold temperatures, which help slow bacterial and viral growth. … Operating rooms are some of the coldest areas in a hospital, usually around 65-69° with a humidity of 70%, to keep the risk of infection at a minimum.
