title: Pantoea intestinalis sp. nov., isolated from the human gut.
abstract: A novel bacterial strain, 29Y89BT, was isolated from a faecal sample of a healthy human subject. Cells were Gram-stain-negative, motile, non-spore-forming and rod-shaped. Strain 29Y89BT formed cream-coloured colonies 2 mm in diameter on trypticase soy agar and showed optimum growth at 35 °C. Strain 29Y89BT showed highest 16S rRNA gene sequence similarity to Pantoea gaviniae A18/07T (98.4 %) followed by Pantoea calida 1400/07T (97.2 %). Multi-locus sequence analysis using atpD (ATP synthase β subunit), gyrB (DNA gyrase), infB (initiation translation factor 2) and rpoB (RNA polymerase β subunit) genes also supported the result of 16S rRNA gene sequence based phylogeny. Strain 29Y89BT showed 62 and 40.7 % DNA-DNA relatedness with P. calida DSM 22759T and P. gaviniae DSM 22758T. Strain 29Y89BT contained C17  : 0 cyclo, C19  : 0 cyclo ω8c, C16 : 0, C14 : 0 and C12 : 0 as predominant fatty acids. In addition, strain 29Y89BT showed physiological and phenotypic differences from its closest relatives P. gaviniae DSM 22758T and P. calida DSM 22759T. The polar lipid profile mainly comprised phospholipids. The DNA G+C content was 59.1 mol%. Thus, based on the findings of the current study, strain 29Y89BT showed clear delineations from its closest relatives P. gaviniae DSM 22758T and P. calida DSM 22759T, and is thus considered to represent a novel species of the genus Pantoea, for which the name Pantoea intestinalis sp. nov. is proposed. The type strain is 29Y89BT ( = DSM 28113T = MCC 2554T).
