How are bacteria cultured for lab work?

Answer 1

Culturing a bacteria means increasing it's numbers so that you can see its colonies with the naked eye.

This is usually done using a culture medium - (an agar plate of some sort, with either a differential or selective base medium), which is a source of nutrition for the bacteria, allowing them to reproduce and grow in ideal conditions.

The original bacterium is placed on the culture medium using aseptic technique (to avoid contamination), and is then usually incubated inverted.

The bacteria will then reproduce and form colonies, which can then be seen by the naked eye. The colonies' characteristics (shape, colour, margin etc) will then be noted and these details will be used to identify the strain of bacteria present if the bacteria was being cultured for identification purposes.

Answer 2

You first add 2,3 gram of Nutrient Agar with into 100ml of distilled. Then hit up until it boil, to then place it in a Petri dish to hit it up in an incubator at 67ºC. Put it jell down for 24 hours. After 24 hours return it so the jell is facing up. Finally let the bacteria culture.

Answer 3

To grow microbes in a lab, you need to insert sperm into your mum's pussy/vagina and then get a baby from incest and kill/burn that baby into ashes and put thashes into a petri dish and burn in more

Answer 4

Bacteria are cultured in the lab by inoculating a small sample into a growth medium containing nutrients and incubating it at the optimal temperature for the specific bacteria. The culture is then monitored for growth, and various techniques can be used to isolate and characterize the bacteria. These techniques include streak plating, pour plating, and spread plating.

Answer 5

Use either a solid agar media or an agar broth autoclaved with an antibotic. Add bacteria to the flask (broth) or streak them out on a petri dish (solid).
