Osmoprotective activity, urea protection, and accumulation of hydrophilic betaines in Escherichia coli and Staphylococcus aureus
The hydrophilic betaines, deanol betaine, triethanol betaine, diethanolthetin and methylethanolthetin, and also thioxanium betaine and citrulline betaine, were accumulated by Escherichia coli. All betaines tested had significant osmoprotective activity for E. coli and, with the exception of citrulli...

Summary: | The hydrophilic betaines, deanol betaine, triethanol betaine, diethanolthetin and methylethanolthetin, and also thioxanium betaine and citrulline betaine, were accumulated by Escherichia coli. All betaines tested had significant osmoprotective activity for E. coli and, with the exception of citrulline betaine and diethanolthetin, also demonstrated urea protection. Staphylococcus aureus accumulated only methylethanolthetin, deanol betaine and thioxanium betaine: the first two had an osmoprotective effect but conferred no urea protection. Diethanolthetin and thioxanium betaine significantly decreased urea tolerance for S. aureus. |
