Optimum Ph agar for growth
    #25185953 - 05/05/18 03:13 PM (3 years, 2 days ago)

I've been searching around for the answer but haven't found anything conclusive.

Been wondering what the optimum pH of agar for mycelium growth is. Checked out the store bought pH of both MEA and PDA, comes out to be 4.7 and 5.6 which is a pretty big difference actually.

Also slightly related to this is study from a thousand years ago on production of psilocybin under submerged culture where they measure pH. Here it seems that pH swings a shitload as growth progresses so i also wonder if it's so important to control initial levels or not.

Any thoughts?
