As I asked before about Escherichia coli regarding tween 20 utilization and got very useful answers, now I wish to construct a model of different substrate utilization scheme for Salmonella spp.
It has been reported that some strains of bacteria especially the Salmonella enter the viable but nonculturable state (VBNC) when they encounter environmental stresses, such as low temperatures, oligotrophic conditions, infiltration press, and biocides including heavy metals and ultraviolet radiation. VBNC bacteria are organisms that fail to grow and develop colonies on media, but their metabolic activity capabilities indicate that they are still alive. Add 3% Tween 20 or 1% catalase enabled cells to make it become culturable again, with resuscitation times of 48 h and 24 h, respectively.
