I just use a simple Tris-based minimal medium for PAO1, and get generation times of about 50 to 60
minutes. However, I HAVE found that it sometimes tends to go "clumpy" if you're not shaking it hard
enough, so I routinely add 40 micrograms/mL of all the natural amino acids (just to help it along).
It's not auxotrophic, though - it IS quite capable of making them itself if it has to..!!
