This depends on the microbes in question. Some microbes are adapted to very hot (thermophiles) or very cold (cryophiles) conditions. But most of the microbes that makes us sick or spoil food prefer conditions right around room temperature, give or take a few degrees. This is why refrigerating food or cooking food can help minimize food spoilage and food borne illness.

∙ 12y agoit 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.

∙ 12y agoIt depends on the bacteria. Normally, thinking about where the bacteria normally like to live is a good starting point. Clinical species like 35-40°C, thermophiles from geothermal vents like 75°C+ and bacteria from the Arctic like cold conditions best.
In summary at least some bacteria like every temperature you will find on the planet best.

∙ 11y agomicrobes hate cold temperatures because they grow slower.
they love the warm and moist temperature as they grow faster.
they hate vinegar because it makes the pH too low.
salt, canned food, and milk heated to 70 degrees Celsius
for 15 seconds kills microbes.
this is all i know really.

At what tenperature is bacteria most active?
It really depends on the bacteria. Some multiply best at room temperature, some at 60 deg celcius. Bacteria has 4 phases in life. The lag, log/exponential, stationary or the death phase. Bacteria multiply best at its log phase. The log phase depends on the bacteria species.
Do bacteria multiply in air?
yup. bacteria is a living thing, so it needs air, obviously.
What is the ideal tempreture zone for bacteria to multiply?
It depends on what kind of bacteria it is.
Can bacteria multiply inside spores?
No, bacteria cannot multiple within a spore. They first have to come out when conditions are favorable, like when they are picked up by a host then get nutrient and multiply.
What temperature range kills bacteria?
different bacteria have different temperature ranges many however are adapted to the temperature of 37 degrees Celsius (core temperature of the human body) so for those bacteria anything above 45 to 50 will usually kill them
Does temperature affect bacteria?
bacteria multiply s and grows quicker when warmer
What is the bacteria at this temperature D not able to multiply?
dormant
What makes Bacteria multiply?
bacteria need to be at the right temperature to multiply (room temperature) which is why we freeze/cook food, temperatures that are to hot and too cold kill the spores (bacteria) and therefore kill them

Why does the freezer preserve food the best?
Bacteria grows slower at colder temperatures. In room temperature, the bacteria will multiply quickly and create mold, but at lower temperatures, the bacteria grows slower, or wont even grow at all.
What are the end points of danger zone the temperature range at which bacteria multiply fastest?
The end points or temperature range of the danger zone, where bacteria multiply the fastest, are typically between 40°F (4°C) and 140°F (60°C). Bacteria multiply best in this temperature range, posing a higher risk of foodborne illness if food is left in this temperature range for too long. It is therefore crucial to keep perishable foods out of the danger zone and ensure proper food storage and handling.
What is the prime danger zone?
Definition? The temperature where hazardous bacteria is likely to multiply at the fastest rate: 98.6°.
Pathogenic bacteria grow best at body temperature?
4.6-7.5
How much bacteria can multiply in a day?
Different types of bacteria will probably multiply at different rates.
What is the optimum temperature for inoculum?
The optimum temprature is that temprature at which bacteria grows and multiply at its full extent, because of its favaurable conditions avialable.
What temperature does bacteria grow in?
It grows best around body temp 37c
What is the best temperature range for medical bacterial growth?
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.
