AB - <jats:title>Abstract</jats:title><jats:p>Almost all bactericidal drugs require bacterial replication and/or metabolic activity for their killing activity. When these processes are inhibited by bacteriostatic antibiotics, bacterial killing is significantly reduced. One notable exception is the lipopeptide antibiotic daptomycin, which has been reported to efficiently kill non-dividing bacteria. However, these studies employed only brief periods of growth arrest. We found that a bacteriostatic concentration of the protein synthesis inhibitor tetracycline led to a time-dependent induction of daptomycin tolerance in<jats:italic>S. aureus</jats:italic>, with<jats:sup>~</jats:sup>100,000-fold increase in survival after 16 h growth arrest relative to exponential phase bacteria. Daptomycin tolerance required glucose and was associated with increased production of the cell wall polymers peptidoglycan and wall-teichoic acids. However, whilst accumulation of peptidoglycan was required for daptomycin tolerance, only a low abundance of wall teichoic acid was necessary. Therefore, whilst tolerance to most antibiotics occurs passively due to a lack of metabolic activity and/or replication, daptomycin tolerance arises via active cell wall remodelling.</jats:p>
