Potato dextrose agar (abbreviated "PDA") is the most widely used medium for growing fungi and bacteria.
[3] Potato dextrose agar is a versatile growing medium for bacteria and fungi (yeasts and molds).
Malt extract agar is more acidic than PDA and is commonly used to cultivate penicillium species.
[1] A similar growth medium, potato dextrose broth (abbreviated "PDB"), is formulated identically to PDA, omitting the agar.
[5] Common organisms that can be cultured on PDB are yeasts such as Candida albicans and Saccharomyces cerevisiae and molds such as Aspergillus niger.
