摘要

从各种藻类和海草样本中获得了九种新菌株。基于 16S rRNA 基因的系统发生树分析表明,所有新菌株都被归入 Rhodopirellula 属。模式菌株被鉴定为 JC737T,它与 Rhodopirellula baltica SH1T 的 16S rRNA 基因序列具有 99.1 % 的相同性,而菌株 JC740 则被认定为一个额外的菌株。菌株 JC737T 和 JC740 的基因组大小分别为 6.6 和 6.7 Mb,G+C 含量为 56.2%。与其他 Rhodopirellula 成员相比,菌株 JC737T 的 ANI 值为 75.8-76.1%,dDDH 值为 20.8-21.3%。该菌株具有多种降解能力,能降解多种复杂的多糖,其中包括以前从未在 Planctomycetota 门成员中发现的粘蛋白。通过对该菌株的系统发生组、泛基因组、形态学、生理学和基因组特征的研究,提出将该菌株命名为 Rhodopirellula halodulae sp.

Genomic and functional insights of a mucin foraging Rhodopirellula halodulae sp. nov.

Nine novel strains were obtained from various algal and seagrass samples. The analysis of the 16S rRNA gene-based phylogenetic tree revealed monophyletic placement of all novel strains within the Rhodopirellula genus. The type strain was identified as JC737T, which shared 99.1 % 16S rRNA gene sequence identity with Rhodopirellula baltica SH1T, while strain JC740 was designated as an additional strain. The genome sizes of strains JC737T and JC740 were 6.6 and 6.7 Mb, respectively, and the G + C content was 56.2 %. The strains cladded distinctly in the phylogenomic tree, and the ANI and dDDH values of the strain JC737T were 75.8–76.1 % and 20.8–21.3 %, respectively, in comparison to other Rhodopirellula members. The strain demonstrated a versatile degradation capability, exhibiting a diverse array of complex polysaccharides, including mucin which had not been previously identified within the members of the phylum Planctomycetota. The phylogenomic, pan-genomic, morphological, physiological, and genomic characterization of the strain lead to the proposal to describe the strain as Rhodopirellula halodulae sp. nov.

期刊介绍: Systematic and Applied Microbiology deals with various aspects of microbial diversity and systematics of prokaryotes. It focuses on Bacteria and Archaea; eukaryotic microorganisms will only be considered in rare cases. The journal perceives a broad understanding of microbial diversity and encourages the submission of manuscripts from the following branches of microbiology:
