Aestuariisphingobium litorale gen. nov., sp. nov., a novel proteobacterium isolated from a water sample of Pearl River estuary

Aestuariisphingobium litorale Li et al. 2020 is a later heterotypic synonym of Chakrabartia godavariana Jani et al. 2019

Chakrabartia godavariana PRB40^T was compared with Aestuariisphingobium litorale SYSU M10002^T to examine the taxonomic relationship between the two type strains. The 16S rRNA gene sequence of C. godavariana PRB40^T had high similarity (99.8 %) to that of A. litorale SYSU M10002^T. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that the two strains formed a tight cluster within the genus Chakrabartia. A draft genomic comparison between the two strains revealed an average nucleotide identity of 97.3 % and a digital DNA-DNA hybridization estimate of 79.5±2.9 %, strongly indicating that the two strains represented a single species. In addition, neither strain displayed any striking differences in metabolic, physiological or chemotaxonomic features. Therefore, we propose that Aestuariisphingobium litorale is a later heterotypic synonym of Chakrabartia godavariana.
