PDA

I just knocked up some agar for the first time in ages. Weighed out the agar, measrured the water and added the  stirred it all up then realised I hadn't cooked up my potatoes. :facepalm:
Damn it. Start again.

Any one ever done the same but actually used it? the PDA agar without the (P) I mean.

If so, what was the result on growth?

Without the "P" in the PDA, you will be missing vital nutrients that are necessary to sustain mycelial growth.
So my guess would be very little growth that'll stall out quickly.

Get cookin'! :wink:

Simple sugars are not nearly enough to keep mycelium healthy, they need a source for starches as well. It would probably grow a bit but I think it would be weak as fuck and would probably end up stalling, as psilo already said.

Conidiation is a biological process in which filamentous fungi reproduce asexually from spores. Potato flakes promote conidiation. In essence, it promotes the actual growth of the culture.

I always find it pretty funny because the fungus breaks down the sugars in the potato primarily into dextrose....it's just that the processes that break it down are more important than just having the dextrose....
