💡 Role in a TC lab (not for plant culture)
PDM is not a plant growth medium — it grows fungi and bacteria. TC labs use it for: identifying contaminating fungi by colony morphology, growing mycorrhizal fungi before inoculation, and maintaining fungal strains from contaminated cultures for identification.
⚠️ Do not use PDM for plant tissue culture — the high dextrose and low mineral content will not support plant growth and may cause osmotic damage.
