摘要

16S rRNA基因序列分析表明，aquimaris Algoriphagus F21T与formosus Algoriphagus XAY3209T序列相似性最高，为100.00%。基于16S rRNA基因和全基因组序列的系统发育分析显示，水貂F21T与台湾水貂XAY3209T形成了一个集群，表明它们之间存在密切的亲缘关系。结果表明，双歧杆菌F21T和台湾双歧杆菌XAY3209T的平均核苷酸同源性（ANIb/m）和数字DNA-DNA杂交值分别为97.48%/97.73%和79.50%，均高于95-96.00%和70.00%的细菌种类划分临界值，表明两株菌株属于同一种。此外，表型和化学分类特征的综合比较进一步验证了这一结论。基于以上所有数据和《国际原核生物命名规则》第42条，我们认为a.a aquimaris Kim et al. 2020是a.f ormosus Ye et al. 2020的后异型同义种。

Reclassification of Algoriphagus aquimaris Kim et al. 2020 as a later heterotypic synonym of Algoriphagus formosus Ye et al. 2020 using a polyphasic approach.

16S rRNA gene sequence analysis indicated that Algoriphagus aquimaris F21^T shared the highest sequence similarity of 100.00% to Algoriphagus formosus XAY3209^T. Phylogenetic analysis based on 16S rRNA gene and whole-genome sequences revealed that A. aquimaris F21^T formed a cluster with A. formosus XAY3209^T, suggesting that there was a close genetic relationship between them. However, the average nucleotide identity (ANIb/m) and digital DNA-DNA hybridization values between A. aquimaris F21^T and A. formosus XAY3209^T were 97.48%/97.73% and 79.50%, respectively, greater than the 95-96.00% and 70.00% cut-off points recommended for delineating bacterial species, which suggested that these two strains belonged to the same species. In addition, the comprehensive comparison of phenotypic and chemotaxonomic characteristics further verified this conclusion. Based on all these data above and rule 42 of the International Code of Nomenclature of Prokaryotes, we propose that A. aquimaris Kim et al. 2020 is a later heterotypic synonym of A. formosus Ye et al. 2020.

期刊介绍： Published by the Microbiology Society and owned by the International Committee on Systematics of Prokaryotes (ICSP), a committee of the Bacteriology and Applied Microbiology Division of the International Union of Microbiological Societies, International Journal of Systematic and Evolutionary Microbiology is the leading forum for the publication of novel microbial taxa and the ICSP’s official journal of record for prokaryotic names. The journal welcomes high-quality research on all aspects of microbial evolution, phylogenetics and systematics, encouraging submissions on all prokaryotes, yeasts, microfungi, protozoa and microalgae across the full breadth of systematics including: Identification, characterisation and culture preservation Microbial evolution and biodiversity Molecular environmental work with strong taxonomic or evolutionary content Nomenclature Taxonomy and phylogenetics.
