Antibiotic persistence does not cause phenotypic heterogeneity in tolerance of Escherichia coli to formaldehyde stress but can preserve it through time

This study investigates whether antibiotic persistence causes phenotypic heterogeneity in Escherichia coli's tolerance to formaldehyde stress and finds that persistence can preserve tolerance over time but is not the cause of initial heterogeneity.

EfgA is a conserved formaldehyde sensor that halts bacterial translation in response to elevated formaldehyde

This study identifies EfgA as a formaldehyde sensor in Methylorubrum extorquens that inhibits translation under formaldehyde stress, without enzymatic detoxification.
