| Abstract: | Strains of Proteus vulgaris utilized only citric acid among the tricarboxylic acids. Citric acid uptake in P. vulgaris IFO 3045 was mediated by a single transport system induced by citrate, isocitrate or cis-aconitate and possessed a weak affinity to isocitric acid. This citric acid transport system corresponds to the system of Salmonella typhimurium or Serratia marce-scens, which is induced by citrate, isocitrate or cis-aconitate and transports citric and isocitric acids. |
