Hello,
I've heard a few rumors from companies that there is more to PDA than just potato infusion, dextrose (glucose), and agar. When we prepare it in our lab and compare to supplier bought PDA, performance of our lab-made medium is less. Has anyone heard of this rumor, or possibly has suggestions on how you make your PDA?
We currently make it using:
Glucose: 20g
Potato infusion powder: 4 g
Agar: 15g
Thanks in advance for any advice!
