Grimontia kaedaensis sp. nov., isolated from the estuary of Kaeda river in Miyazaki, Japan

Abstract

Strain 020920NTwas isolated from the estuary of the Kaeda river in the Miyazaki prefecture in Japan. Phylogenetic analysis based on the 16S rRNA gene showed the strain’s close evolutionary relationship with bacteria from the genusGrimontia, in the familyVibrionaceae. Phenotypic and chemotaxonomic features of the strain were investigated. Whole genome sequencing revealed that the strain 020920NTgenome consists of two chromosomes and a plasmid, for a total of 5.52 Mbp. Calculations of whole genome average nucleotide identity and phylogenetic analysis based on the whole genome sequence showed that the strain represents a new species in the genusGrimontia, for which we propose the nameGrimontia kaedaensissp. nov. with the type strain 020920NT(=LMG 32507T=JCM 34978T).
