Viable but nonculturable (VBNC) bacteria refers as to bacteria that are in a state of very low metabolic activity and do not divide, but are alive and have the ability to become culturable once resuscitated.

Oct 1, 2023 · Viable but nonculturable (VBNC) cells are characterized by their loss of culturability, ability to maintain a nonculturable state, and potential to resuscitate. The formation of VBNC cells can occur under a wider range of stress conditions, …

Many bacterial species have been found to exist in a viable but non-culturable (VBNC) state since its discovery in 1982. VBNC cells are characterized by a loss of culturability on routine agar, which impairs their detection by conventional plate count techniques.

VBNC status is a survival strategy adopted by many bacteria in response to adverse environmental conditions (Ayrapetyan et al. 2018; Dong et al. 2020; Yoon and Lee 2020). In the case of VBNC, bacteria cannot grow on a routine culture medium, while their live and metabolic activities continue.

Viable but nonculturable (VBNC) cells are characterized by their loss of culturability, ability to maintain a nonculturable state, and potential to resuscitate. The formation of VBNC cells can occur under a wider range of stress conditions, many of …

Under stress conditions, many species of bacteria enter into starvation mode of metabolism or a physiologically viable but non-culturable (VBNC) state. Several human pathogenic bacteria have been reported to enter into the VBNC state under these conditions.

Oct 21, 2024 · In this present review, we mainly focus the VBNC state of Vibrios and other human bacterial pathogens. Exposure to several factors like nutrient depletion, temperature fluctuation, changes in salinity and oxidative stress, antibiotic and …

Sep 24, 2018 · Bacteria have evolved numerous means of survival in adverse environments with dormancy, as represented by "persistence" and the "viable but nonculturable" (VBNC) state, now recognized to be common modes for such survival.

Viable but nonculturable (VBNC) microorganisms have been recognized as pathogenic contaminants in foods and environments. The failure of VBNC cells to form the visible colonies hinders the ability to use conventional media for their detection.

Mar 18, 2020 · Escherichia coli O157:H7 and Salmonella enterica are leading causes of foodborne outbreaks linked to fresh produce. Both species can enter the “viable but nonculturable” (VBNC) state that precludes detection using conventional culture-based or molecular methods.
