Recent Progress in Molecular Mechanism of Acid Resistance in Escherichia coli

doi:10.7506/spkx1002-6630-201521051

Abstract

Abstract:

Some strains of Escherichia coli are resistant to strong acid and can survive in acidic conditions, mainly because
they have a variety of acid resistance mechanisms, including a glucose-repressed system, amino-acid-dependent system,
chaperone proteins and systems for stabilizing membrane charge. Understanding the molecular mechanisms of acid
resistance in E. coli can provide new insight into controlling contamination in the food processing industry, and play a
positive role in clinical prevention and treatment of foodborne pathogens. In this paper, the molecular mechanisms of acid
resistance in E. coli are reviewed.

Key words: Escherichia coli, glucose-repressed, amino-acid-dependent, chaperone proteins, membrane charge, crossprotection
