Abstract
The dependence of H2 production on the formate channels, FocA and FocB, by Escherichia coli at pH 5.5, 6.5 and 7.5 was shown using focA and focB mutants and comparing with the wild type. Moreover, effect of exogenous addition of formate (10Â mM) on H2 production was allotted. The results acquired propose that during glucose fermentation formate import can occur through FocB at different pHs; external formate drives FocA to import direction. However, during glycerol fermentation formate might be imported through FocB, whereas formate is exported preferentially through FocA at pH 7.5.
