How do you prepare culture media?
Dehydrated media for broth cultures need to be prepared by dissolving in distilled water and adjusting the final pH prior to sterilization. Powdered media for agar cultures must be dissolved in distilled water, stirred, then boiled or autoclaved prior to pouring into sterile petri dishes using aseptic techniques.
What are the preparation and sterilization procedures for culture media?
Agar-free media will usually dissolve on gentle agitation. Media containing agar should be heated to dissolve the agar before autoclaving. Bring the medium to the boil without scorching or burning. Most culture media will require final sterilization in an autoclave at 121°C for 20 minutes.
What are the different culture media used in experiments?
