Comment on 'UV Disinfection Induces a VBNC State in Escherichia coli and Pseudomonas aeruginosa'

摘要

Viable but nonculturable (VBNC) is described as a condition where cells lose culturability upon exposure to environmental stress, but retain their viability and potential to revert to a metabolically active and infectious state. These observations have generated interest in understanding the role of VBNC in water disinfection and potential public health implications. Zhang et al. presents a study on the potential of UV disinfection to induce VBNC in bacteria.2 In reviewing the study, fundamental concerns were identified with the methods used, which deviate from standard practice, calling into question their results and subsequent conclusions.
