2023年10月1日 · 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 which are moderate and long-term in nature.

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. [1] Bacteria in a VBNC state cannot grow on standard growth media, though flow cytometry can measure the viability of the bacteria. [1]

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.

Viable but non-culturable (VBNC) state is a dormant-like state of bacteria, and many species of bacteria can enter into this state when suffering stress conditions. VBNC bacterial cells can resuscitate to culturable state and recover their pathogenicity when conditions become favorable.

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 …

2024年10月21日 · 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 other chemical stress can induce the cells to VBNC state.

In this review, we describe these two dormancy strategies, characterize the molecular underpinnings of each state, and highlight the similarities and differences between them. We believe these survival modes represent a continuum between actively growing and dead cells, with VBNC cells being in a deeper state of dormancy than persister cells.

2 天之前 · This phenomenon is a defence mechanism that allows cells to tolerate stress and maximize population fitness. The investigation of the VBNC state is of high importance for the food industry, as the impacts of VBNC induction and single cell outgrowth heterogeneity can contribute to false-negative detection outcomes.

there are significant differences between VBNC cells and persister cells, including their induction stress, cellular phenotypes (such as culturability, morphology, capability of maintenance and re- suscitation), and study procedures (Figure 1).
