Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or low acid. There are exceptions: some bacteria thrive in extreme heat or cold.
In this manner, how does temperature affect growth of bacteria?
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.
Also Know, what temperature do viruses grow?
"Some germs, known as hyperthermophilic bacteria, grow in very hot temperatures up to 250°F. However, most bacteria and viruses that are pathogenic to humans can be killed through a heat of 165ºF or higher within minutes of cooking." According to the New York Department of Health.
At what temperature does most bacteria stop growing?
Most food poisoning bacteria multiply at temperatures between 5°C and 63°C. This range of temperatures is called the Danger Zone. Room temperature is usually within the Danger Zone. Bacterial growth slows down or stops in food that is kept at temperatures colder than 5°C or hotter than 63°C.
Can bacteria grow below 0 degrees?
Most disease-causing bacteria have evolved to thrive at temperatures close to that of the human body. The average household freezer maintains a frosty -18 degrees Celsius (0 degrees Fahrenheit) or below: in these conditions there is no liquid water available and the enzymes bacteria rely on cannot function.
