Can E coli survive in sea water?

Can E coli survive in sea water?

Survival of E. coli in seawater/distilled water mixtures at different ratios (0, 25, 50, 75 and 100% seawater) for 48 h showed an optimal survival (74%) at 25% seawater. Survival in the end members – distilled water and seawater – was 60% and 8%, respectively [48].
