Figure 3From: Release of extracellular ATP by bacteria during growthExtracellular ATP level changes during bacteria growth. Overnight cultures of Salmonella SE2472 (A) or ST14028s (B), E. coli K12 (C) or BW25113 (D), were diluted 1:100 in LB broth and cultured at 37°C with shaking. Aliquots were collected at various time points for measuring OD600nm and culture supernatant was harvested for ATP assays. The ATP levels in the culture supernatant were normalized against OD600nm and plotted against incubation period. Results are the average from 3 to 8 experiments and error bars represent standard deviations.Back to article page
