Recovery of injured Escherichia coli

ED-1829 ColV,I-K94, a derivative of Escherichia coli K-12, were injured with hydrogen peroxide, acetic, and formic acid for various length of time at acidic pH(s) in Nutrient Broth 2. The acid injured organisms recovered significantly better in the media containing phosphate than the media without p...

Zusammenfassung:ED-1829 ColV,I-K94, a derivative of Escherichia coli K-12, were injured with hydrogen peroxide, acetic, and formic acid for various length of time at acidic pH(s) in Nutrient Broth 2. The acid injured organisms recovered significantly better in the media containing phosphate than the media without phosphate. Phosphate helped in plating efficiency of the injured bacterial population and somehow expedite the recovery process of the acid stressed organisms.
