Scholarcy highlights

  • The aim of this study was to determine the influence of respiratory chain inhibitors upon iron reduction in Aeromonas hydrophila strain KB1
  • Optimal conditions of the reduction process were established by determining the amount of biomass, optimal pH, temperature and substrate concentration
  • The substrate concentration used in our study was such as to allow the maximum iron reduction rate
  • Dicumarol was used as an inhibitor of the quinone loop, while quinacrine was used to inhibit alloxazine centers
  • The observed inhibition of iron reduction by rotenone and capsaicin may suggest the existence of Q sites in formate reductase, analogous to those in complex I
  • Lack of inhibition of iron reduction by azide suggests that complex IV does not participate in this process
