Effect of heating at 50°C for 60 min on classical injury of Escherichia coli MRE162 cells

Temp (°C)	Injury (% ± SE) determined on LB agar plates witha:
	10 μg ml−1 polymyxin	0.1% (wt/vol) sodium deoxycholate	4% (wt/vol) sodium chloride	ROS scavengers catalase, SOD, and sodium pyruvate
37	1.13 ± 0.48	10.77 ± 3.11	7.14 ± 2.63	1.13 ± 0.16
70	35.71 ± 5.33	93.57 ± 2.80	98.86 ± 0.73	2.28 ± 0.31

^aInjury is expressed as the percentage of the difference between counts on nonsupplemented and supplemented media.
