Abstract

Strain PFL01T was isolated from traditional Korean fermented clam, jogae-jeotgal, and characterized. The strain was a facultative anaerobic, Gram-stain-negative bacterium that was rod-shaped, motile and beige-pigmented. The phylogenetic sequence analysis based on the 16S rRNA gene from PFL01T revealed that it was closely related to Lelliottia nimipressuralis LMG 10245T and Lelliottia amnigena LMG 2784T with 99.3 and 99.3 % sequence identities, respectively. Multilocus sequence type analysis of concatenated partial aptD, gyrB, infB and rpoB gene sequences showed a clear distinction of strain PFL01T from its closest related type strains. The discrimination was also supported by unique repetitive extragenic palindromic PCR (Rep-PCR, ERIC-PCR) fingerprint patterns. In addition, results from average nucleotide identity analyses with other species were less than 85 %. vitek and API analyses revealed distinct characteristics from other species of Lelliottia. The cellular fatty acid profile of the strain consisted of C16 : 0, cyclo-C17 : 0, C16 : 1ω7c/C16 : 1ω6c and C18 : 1ω7c/C18 : 1ω6c as major components. The whole genome of PFL01T was 4.6 Mb with a G+C content of 55.3 mol%. Based on these results, strain PFL01T was classified as a novel species of the genus Lelliottia, for which the name Lelliottia jeotgali sp. nov. is proposed. The type strain in PFL01T (=KCCM 43247T=JCM 31901T).
