Naturally occurring betaines, especially glycine betaine and proline betaine, were accumulated by Escherichia coli from urine. In synthetic hyperosmotic medium, with an homologous series of added betaines, (CH3)3N(+)-(CH2)n-COO-, osmoprotective activity and intracellular accumulation decreased monotonically as n increased from 1 to 5. In contrast, alpha-substituted glycine betaines were accumulated in a similar manner to glycine betaine, but with different osmoprotective activities. Arsenobetaine, with a quaternary arsonium group, was also accumulated but amino acids which can become negatively charged in a chemically basic environment were not.
