sp. nov., a novel bacterium isolated from Adélie penguin oral cavity.

The taxonomic status of strain P5891, isolated from an Adélie penguin beak swab, was investigated. Based on the 16S rRNA gene sequence, the strain was identified as a potentially novel species, with the highest sequence similarities to FRC0190 (96.7 %) and DSM 45586 (96.6 %). The average nucleotide identity values between strain P5891 and FRC0190 and DSM 45586 were 68.2 and 69.2 %, respectively. The digital DNA-DNA hybridization values between strain P5891 and FRC0190 and DSM 45586 were 23.7 and 21.4 %, respectively. Phylogenetic trees based on the 16S rRNA sequence placed strain P5891 in a separate branch with 1170 and 1045, while a phylogenomic tree based on the species core genome placed the strain next to 200CH. Extensive phenotyping and genomic analyses clearly confirmed that strain P5891 represents a novel species of the genus , for which the name sp. nov. is proposed, with the type strain P5891 (=CCM 8862=LMG 31627).
