Abstract
Strains 97/79T and A121, recovered respectively from human faeces and well water, were compared to currently known species of the genus Citrobacter using genotypic and phenotypic approaches. Multilocus sequence analysis based on housekeeping genes fusA, leuS, pyrG, rpoB and recN, showed that the two strains formed a distinct phylogenetic lineage within the genus Citrobacter. Average nucleotide identity (ANI) between strains 97/79T and A121 was 99.2 %, whereas ANI values of strain 97/79T with the type strains of closely related species of the genus Citrobacter, C. werkmanii, C. braakii, C. freundii, C. youngae and C. pasteurii, were all below 93.0 %. The ability to metabolize different compounds also discriminated strains 97/79T and A121 from other species of the genus Citrobacter. Based on these results, strains 97/79T and A121 represent a novel species of the genus Citrobacter, for which the name Citrobacter europaeus sp. nov. is proposed, with strain 97/79T (=CIP 106467T=DSM 103031T) as the type strain. The DNA G+C content of strain 97/79T is 52.0 %.Entities:
