Into a second flask, add charcoal, yeast extract, alpha-keto-glutarate, and agar. Mix the dry powders. Pour the buffer solution into the second flask containing the dry powders and mix. Carefully heat to dissolve the agar, then sterilize by autoclaving at 121 °C for 15 minutes. Immediately place the medium in 50 °C water bath.

Thayer–Martin agar (or Thayer–Martin medium, or VPN agar) is a Mueller–Hinton agar with 5% chocolate sheep blood and antibiotics. It is used for culturing and primarily isolating pathogenic Neisseria bacteria , including Neisseria gonorrhoeae and Neisseria meningitidis , as the medium inhibits the growth of most other microorganisms.
Agar plates Organisms are placed or streaked onto petri dishes Provides a solid surface for stationary growth, compact and stackable Agar based dipsticks Essentially miniature agar plates in the form of dipsticks Diagnostic purposes, can be used anywhere, cost effective, easy to use Selective and differential media
Label the base of the plate. Then, visualize the plate in four quadrants: top left (I), top right (II), bottom right (III), bottom left (IV). Streak the mixed culture back and forth in the first quadrant (top left) of the agar plate. Do not cut the agar, simply scrape the top. Flame the loop to rid of culture residue.
Nutrient agar is a general-purpose solid medium supporting growth of a wide range of non-fastidious organisms. It typically contains ( mass/volume ): [ 1 ] 0.5% peptone – this provides organic nitrogen
