title: [Utilization and fermentation of 2-ketogluconate by "Enterobacteriaceae" (author's transl)].
abstract: Two methods were compared: 1) the ability to use 2-ketogluconate (2-KG) as source of carbon and energy in defined medium, and 2) the ability to produce acid by fermentation of 2-KG (0.5 g/100 ml) in peptone water with phenol red. Results of growth on, and acid production from, 2-KG were identical. A total of 990 strains was studied. No strain of Escherichia coli, Shigella (4 species), Salmonella (4 sub-genera), Yersinia pestis, Y. pseudotuberculosis, Edwardsiella (2 species), Proteus vulgaris, P. mirabilis, P. morganii, Providencia (2 species) could utilize 2-KG. All strains of Citrobacter (2 species), Levinea amalonatica, Klebsiella pneumoniae, K. oxytoca, K. ozaenae, Enterobacter (5 species), Serratia (6 species) utilize 2-KG as sole carbon source. Different reactions were given by strains of P. rettgeri, Y. enterocolitica and K. rhinoscleromatis.
