Abstract excerpt

Oxidant stress inhibits the growth of Escherichia coli, which is partially relieved by adding asparagine to the culture medium. Asparagine synthetase (AS), assayed using hydroxylamine as an amino donor, was decreased in a concentration-dependent manner by exposure of cultures to oxygen from near-...
