“These iron memories persist for at least four generations and disappear by the seventh generation.”
Make note that for example “when well fed, E. coli bacteria divide once every 20 minutes”[1], making that iron memory last for 80 to 140 minutes. Though that may still be longer than it takes them to discard a plasmid (genetic “loose change” on e.g. immunity resistance) when competing for reproductive speed.
