Prominent role of γ -glutamyl-transpeptidase on the growth of Helicobacter pylori

Figure 2 Effect of GGT on the growth of H pylori. H pylori strain NCTC 11 637 was cultured microaerobically in BHI broth medium supplemented with 10% fetal bovine serum at 37 °C nd in the presence of either different concentration of GGT inhibitor or stimulator. A: Effect of 2 mmol/L ( ■square), 4 mmol/L (▲triangle), 6 mmol/L (× ross), 8 mmol/L (* star) SBC and GGT stimulation (0.1 mol/L GSH +1 mol/L glycyl-glycine,●ircle) on NCTC 11637 over 21 d. Control (◆iamond). B: Effect of 10 mmol/L SBC on NCTC 11637 over 72 h. Viability was determined continuously at time intervals. (CFU: colony-forming units).
