In Salmonella typhimurium, methionine auxotrophs such as metB can use D-methionine as a methionine source. MetP mutations prevent this growth since D-methionine can enter only via the metP high-affinity methionine transport system. D-methionine utilising revertants ( Dmu +) were selected from metB23

## Abstract __Salmonella typhimurium__ strain 4a is a temperature‐sensitive division mutant. At 39° or 42° in several media a septation lesion occurs since non‐septate filaments form at these temperatures. At lower temperatures in some media separation is aberrant since long chains of cells are for
## Abstract The effect of inhibitors and uncouplers on the osmotic shock‐sensitive transport systems for glutamine and galactose (by the β‐methyl galactoside permease) was compared to their effect on the osmotic shock‐resistant proline and galactose permease systems in cytochrome‐deficient cells of
