Abstract
The photosynthetic bacterium Rhodobacter sphaeroides f. sp. denitrific ans IL106 can grow in high osmolarity. The accumulation of intracellul ar inorganic ions and organic solutes in cells grown in a synthetic me dium containing different concentrations of NaCl was examined. Togethe r with potassium ion, trehalose was the major organic osmoprotectant a nd its accumulation depended on the external salt concentration. Intra cellular levels of glycine betaine and other osmoprotectants such as p roline did not change when osmolarity increased.
