The Impact of Pyroglutamate: Sulfolobus acidocaldarius Has a Growth Advantage over Saccharolobus solfataricus in Glutamate-Containing Media

Figure 3

Concentration of intracellular glutamate and pyroglutamate. Glutamate (black) and pyroglutamate (red) concentrations were determined after exponential phase during growth of Sulfolobus acidocaldarius MW001 and Saccharolobus solfataricus P2 on 24 mM L-glutamate. Values represent the average of four independent cultivations. Error bars represent the standard error between the four experiments.
