What are needed to grow bacteria?

Answer 1

Bread, Cakes, Yoghurt etc...

Answer 2

All bacteria require a steady supply of some form of nutrients, though it may differ wildly from species to species. Phototrophic bacteria use photosynthesis, chemoautotrophs use chemicals. Some bacteria (aerobes) need oxygen, while others (anaerobes) will die immediately if exposed. Temperature requirements vary as well. Certain species can handle colder temperatures, while others need warmer conditions. A place to attach is important.

Extremophiles are bacteria that thrive in extreme conditions that normally kill all organisms. Thermophiles live in boiling hot waters, such as the hot springs in Yellow Stone National Park. Halophiles need high levels of salt in their environment.

Answer 3

Bacteria is a living organism , so it needs common "life behold" things such as air, food, and a living environment. "They" , so to speak, like to be kept in a warm, moist place. Also they tend to "enjoy" (grow better) in things that also have sugar and organic matter.

Answer 4

Agar with a nutrient suitable for the desired bacteria.

If you need to count them, then a reagent is needed too, that one can see a difference on the agar plate where bacteria colonies have grown.

To apply the sample, you need sterile equipment to dilute it to desired concentration and a spatula to spread it on the plate.

Then you need a sterile place to incubate the plates at the right temperature, e.g. 37 °C.

For professional counting, one often can use a binocular microscope and a hand counter.

Answer 5

food,warmth,oxygen the same as most things
