A novel role for the glutamate decarboxylase system in Listeria monocytogenes; protection against oxidative stress

The GAD system is widely present in several types of organisms and is known to play an important role in bacterial acid tolerance. There is only one account of this system playing a role in oxidative stress in bacteria and one in yeasts. Here we show for first time that it affects the oxidative stress resistance of a Gram-positive bacterium, (L. monocytogenes, tested in three strains; 10403S, EGD-e, and LO28). We found a statistically...
