Good buffers are a good choice only if the bacteria do not degrade them.
They are a bad choice, in my opinion, for enrichment cultures, since you may
enrich for buffer degraders. Sodium bicarbonate and sodium carbonate, are a
better choice. The carbon dioxide buffer system is more ecologically
correct than most other buffers.
