From: Photodynamic inactivation and its effects on the heterogeneity of bacterial resistance
Bacterial populations with a highly heterogeneous response tend to have broad survival fractions at different antibiotic concentrations, usually indicating a resistant phenotype. By using photodynamic inactivation, i.e. irradiating bacterial cultures with a photosensitiser, cells that survive oxidative stress are more homogeneous in their response to antibiotics, similar to phenotypically sensitive profiles.
