Abstract

Four Gram-stain-negative, aerobic, rod-shaped bacteria, designated WL0002^T, WL0024^T, WL0050^T, and WL0075^T, were isolated from sediment in the coastal areas of Nantong City, China. Metagenomic analysis revealed higher relative abundance of taxa closely related to the four strains in sediment (0.79-2.0 %) than in water (0.34-1.3 %) (Mann-Whitney U test: p < 0.001). Phylogenetic analysis based on 16S rRNA gene and the bac120 gene set both suggested that the four strains are closely related to the genus Defluviimonas. Additionally, Albidovulum inexpectatum DSM 12048^T formed a distinct branch within Defluviimonas. The evolutionary distance (ED) and percentage of conserved proteins (POCP) analysis indicated that the four strains and the genus strains of Albidovulum and Defluviimonas should be recognized as a single genus. Genomic relatedness analysis among the four strains and type strains of the genera Albidovulum and Defluviimonas was below species delimitation thresholds, except for strains WL0024^T and "D. salinarum" CAU 1641^T, which should belong to the same species. Based on phenotypic and genotypic characterization, the four strains should be recognized as novel species in Albidovulum, and it is reasonable to reclassify the genus Defluviimonas as a later heterotypic synonym of Albidovulum, consistent with the classification of the Genome Taxonomy Database (GTDB). Four names are proposed as follows: Albidovulum marisflavi sp. nov. (type strain WL0002^T = MCCC 1K06013^T = JCM 34653^T = GDMCC 1.2437^T), Albidovulum salinarum sp. nov. (WL0024^T = MCCC 1K06062^T = JCM 34656^T = GDMCC 1.2438^T), Albidovulum litorale sp. nov. (WL0050^T = MCCC 1K07524^T = JCM 35566^T = GDMCC 1.3084^T), and Albidovulum sediminicola sp. nov. (WL0075^T = MCCC 1K06064^T = JCM 34660^T = GDMCC 1.2419^T).

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:
