20 to 40 degree's
It depends on species; most bacteria develop rapidly between 20 and 40°C. Those that are pathogenic to humans are normally cultivated around body temperature, 37±3°C for fast analysis.
Most bacteria stop growing at temperatures close to 0°C. Also most bacteria die at about 70°C, but there are pathogenic bacteria that need 121°C to be killed off.
Refrigerators shall have max 8°C temperature to reduce bacterial growth, 2°C for storing of fish (hence ice boxes are used). Food shall be warmed above 70°C fast and cooled rapidly to below 8°C to according to EU rules for cooking.
There are though extreme environment bacteria e.g. thermophile ones that thrive in heat. In freezing environments many bacteria go to a kind of hibernation mode, as "spores", where they survive but don't reproduce. The kryophiles like temperatures even below 0°C, where some even reproduce.

There are though extreme environment bacteria e.g. thermophile ones that thrive in heat, i.e. 45-100 °C. In freezing environments many bacteria go to a kind of hibernation mode, as "spores", where they survive but don't reproduce. Others, the kryophiles, like cold and some can reproduce below 0 °C. Colwellia has metabolism even at -200 °C.
Bacterial ideal temprature zone vary with different species they can be divided in following types:
Psychrophiles: they love cool environment and grow in temp below 20o
Mesophiles: they can grow normally in temp range between 35 to 45
Thermophiles: they are able to grow at temprature higher then 80o
The best temperature for bacterial growth is around the same temperature as the human body, 98.6 degrees F (37 degrees C).
we incubate at 25 degrees Celsius because it is room temperature and it is the best temperature to grow bacteria that lives on objects like the counters, and sinks.
18 degrees C
the comfortable summer temperature is around 80 or 90 degrees.
12'C
80 Fahrenheit would be more comfortable.
There are a few different temperatures that allow you to grow bacteria. Warm temperatures tend to grow bacteria rather well.
It is actually wrong. The bacteria grow fastest in incubators.
4.6-7.5
Yep. There are some uncommon bacteria (psycrophiles) that are able to grow at low temperature, as Arthrobacter.
It grows best around body temp 37c
Because pathogenic bacteria love to grow at room temperature.
Food spoilage happens when bacteria in the food is allowed to grow. The food heats up to room temperature or hotter and the bacteria grow allowing it to spoil.
There are a number of bacteria that can grow on meat at room temperature, including Salmonella, E. coli, Staphylococcus, Streptococcus and Listeria.
It depends on what the bacteria is. If it is a bacteria that infects humans, then a temperature of 36-38 degrees C. Some bacteria like cold temperatures and some will grow in hot springs.
moisture noruishes bacteria. the wet damp atmosphere is an ideal conditions for bacteria to grow. the temperature also has a rapid effect on bacteria, the warmer the climate, the more easily bacteria is grown.
Bacteria all have a specific optimum growth temperature. When the temperature is not at the optimum, growth is slowed down. When it is too cold, the bacteria will still be alive, but growth will be very slow and spoilage will happen slower.
the endospore would protect the bacteria and can last the temperature
