Culturability of V. campbellii BAA-1117™ (light grey) and V. japonicus UU24 (dark grey). Different treatments were considered: (i) after resuscitation on TSB-NaCl agar plates, (ii) without resuscitation on TSB-NaCl agar plates treated with catalase and (iii) without resuscitation on TSB-NaCl agar plates. Cells from V. campbellii BAA-1117™ microcosm were not yet completely in VBNC state (31 days). Cells from V. japonicus UU24 microcosm were in VBNC state (179 days). Use of catalase greatly improved the culturability of the cells for both strains. Significant differences were observed among treatments for each strain (t-test, p < 0.05). Counts (CFU/ml) are reported as Log10(CFU + 1)
