How can you get uncontaminated culture
This storyboard does not have a description.
Today we are going to do a required practical: How can you get uncontaminated culture
Firstly, get a petri dish and put it near a flame so no bacteria from the surroundings get in the dish therefore ensuring it does not get contaminated
Secondly, get an inoculating loop and sterilise it by hovering it over a flame
Thirdly, get your chosen bacteria and carefully spread it over the agar jelly making sure that you don't create any dents in it
Then, close the petri dish and seal it so that the culture does not get contaminated
Finally, place the petri dish upside down in a water bath at 25 degrees to obtain uncontaminated culture
