Utilization of D-xylose by wild-type strains of Salmonella typhimurium. 1979

R P Mortlock, and D C Old

Enzyme studies of strains of Salmonella typhimurium representing biotypes that utilized D-xylose rapidly (xylose strong) or slowly (xylose weak) showed that they were different in the utilization of D-xylose because the xylose-weak strains were deficient in the transport of D-xylose. This observation is consistent with the idea that strains of the different xylose-weak biotypes, e.g. biotypes 17 to 32, were descended from strains of xylose-strong types, particularly from biotype 1.
