The nonpathogenic E. coli strain 35218 was selected
for this study because E. coli strain 35218 is more resistant to PEF
treatment than E. coli O157:H7 and may be a more suitable surrogate
bacterium in PEF challenge studies with acidic beverages than other
non-pathogenic strains of E. coli (Gurtler, Rivera, Zhang, & Geveke, 2010)
