- Abstract
A novel Gram-stain-negative bacterial strain, CHu64-6-4T, was isolated from a 67-cm-long sediment core collected from the Daechung Reservoir at a water depth of 17 m, Daejeon, Republic of Korea. The cells of strain CHu64-6-4T were aerobic nonmotile and formed colorless colonies on R2A agar. The phylogenetic analysis based on 16S rRNA gene sequencing indicated that the strain formed a separate lineage within the family Oxalobacteraceae, exhibiting 97.2% and 97.1% 16S rRNA gene sequence similarities to Glaciimonas singularis and Paraherbaspirillum soli, respectively. Strain CHu64-6-4T showed less than 74.4% average nucleotide identity compared to the type strains of related genera within the family Oxalobacteraceae. In the UPGMA dendrogram based on the ANI values of genomic sequences, strain CHu64-6-4T formed an evolutionary lineage independent of the genera Glaciimonas and some other taxa. The chemotaxonomic results showed Q-8 as the predominant respiratory ubiquinone, phosphatidylglycerol, diphosphatidylglycerol, and phosphatidylethnolamine as the major polar lipids, Summed Feature 3 (C16:1ω7c and/or iso-C15:0 2-OH), C16:0, and C18:1ω7c as the major fatty acids, and a DNA G+C content of 62.1 mol%. The combined genotypic and phenotypic data showed that strain CHu64-6-4T could be distinguished from all genera within the family Oxalobacteraceae and represents a novel genus, Lacisediminimonas profundi gen. nov., with the name Lacisediminimonas profundi sp. nov., in the family Oxalobacteraceae. The type strain is CHu64-6-4T (=KCTC 62287T=JCM 32676T).
