(a) Workflow – Induction and confirmation of the viable but non-culturable state, (b) ATP determination of non-culturable L. monocytogenes. Additionally, the viable cell count (cells/ml) was determined using the LIVE/DEADTM BacLightTM viability assay (green). (c) Development of cells after reuptake in BHI medium; control (mock): culturable cells, negative control (disinfection), VBNC cells 1 h after reuptake in BHI and VBNC cells 24 h after reuptake in BHI; scale: 20 µm, enzymatic activity and ability to ferment sugar by L. monocytogenes were measured by the API 20E system.
