So what is agar? It's a gelatinous medium providing nutrients and a stable controlled environment for bacteria growth. Most bacteria will grow well using nutrient agar, but some more fastidious bacteria prefer tryptic soy agar.
To prepare agar plates, just heat and pour into one of your selected sterile petri dishes. Next, collect bacteria: Swab along any surface to test (your mouth, the bathroom counter, etc.). To culture your microbes, lightly smear the swab in a zig-zag pattern on the surface of the agar plates. Within 1-2 weeks, you should see signs of bacterial growth.
Now you know where to buy petri dishes. But maybe you’re unsure what to add to your cart. We can help with your order!
