Biochemical characteristics of Enterobacter agglomerans and related strains found in buckwheat seeds.
Thirty strains of bacteria were randomly isolated and identified from buckwheat seeds. The phenotypic characteristics of these strains agreed well with those of the Enterobacter agglomerans-Erwinia herbicola complex. On the basis of the difference in indole production and gas production from smallcap˜D-glucose, the isolates were divided into 3 phenotypic groups (I, II and III). Twenty two strains were in phenotypic group I, which were negative for indole production and gas production from smallcap˜D-glucose and resembled Pantoea agglomerans. All 6 strains in phenotypic group II, which was positive for indole production and negative for gas production from smallcap˜D-glucose, were identified as Erwinia ananas [P. ananas pv. ananas]. Two strains in phenotypic group III, which was negative for indole production and positive for gas production from smallcap˜D-glucose, were identified as Rahnella aquatilis.
