Some organic acids have no inhibitory effect on microorganisms for example, gluconic acid is a highly polar molecule, and is unable to penetrate the cell membrane of E. coli 0157 H7 (Bjornsdottir, Breidt, Jr., and McFeeters, 2006). A tolerance response in Salmonella enterica sv. Typhimurium, induced by lactic acid, will, however, induce sensitivity to hydrogen peroxide (Greenacre et al., 2006).
