how do you culture bacteria?

Answer 1

If you mean how do you culture, pure cultures of bacteria, then one of the easiest ways is to get a culture plate of generic media (broad appeal media, not specific to certain bacteria types), clean a nichrome wire in a flame, dip it into whatever has bacteria you wanna try and culture (old mayonnaise, rotten meat, lake water), streak (run it back and forth along one side of the media), clean the wire in the flame, alter the media by 90 degs, streak again, making sure the wire passes into the area previously streaked a few times, repeat one more time, place the lid on the plate, turn upside down and place in a incubator for 24 to 48 hours. Pure cultures (those grown from a single bacterium) will have grown up in the second and third streaking areas.

Answer 2

A fundamental method of studying bacteria is by culturing them in liquid media or on the surface of media that have been solidified by agar. Media contain nutrients, varying from simple sugars to complex substances such as meat broth. To purify or isolate a single bacterial species from a mixture of different bacteria, solidified media are generally used. Individual cells dividing on the surface of solidified media do not move away from each other as they do in liquid, and after many rounds of replication they form visible colonies composed of tens of millions of cells all derived by binary fission from a single cell. If a portion of a colony is then transferred to a liquid medium, it will grow as a pure culture, free of all other bacteria except the single species that was found in the colony.

Answer 3

You place bacteria food in a container, every bacteria likes different food. By knowing what food a specific bacteria likes then you find out if what you've put in the container has the bacteria...Hope i have explained myself :)
