I've seen a couple of recipes of minimal media with EDTA added, but can't
work out why it's there. Does anyone knows the reason? It occurs to me
that perhaps EDTA serves a reservoir of divalent cations which can be
released when needed, but surely EDTA has a higher affinity for the cations
than enzymes, how else could it inactive enzymes?
