Osmoprotection of Escherichia coli by peptone is mediated by the uptake and accumulation of free proline but not of proline-containing peptides.

Applied and environmental microbiology - 1 Dec 1999

Amezaga M R, Booth I R

Abstract excerpt

The effect of meat peptone type I (Sigma) on the growth of Escherichia coli cells under hyperosmotic stress has been investigated. Peptone is a complex mixture of peptides with a small content of free amino acids, which resembles nutrients found in natural environments. Our data showed that peptone enhances the growth of E. coli cells in high-osmolarity medium to levels higher than those achieved with the main...
