Abstract
Two Gram-positive, non-motile, short rod-shaped actinomycete strains, designated as A18JL241T and Y20T, were isolated from deep-sea sediment samples collected from the Southwest Indian Ocean and Western Pacific Ocean, respectively. Both of the isolates were able to grow within the temperature range of 5-40 °C, NaCl concentration range of 0-7 % (w/v) and at pH 6.0-12.0. The two most abundant cellular fatty acids of both strains were anteiso-C15 : 0 and anteiso-C17 : 0. The major polar lipid contents of the two strains were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and one unidentified glycolipid. These two strains shared common chemotaxonomic features comprising MK-10 and MK-12 as the respiratory quinones. The genomic DNA G+C contents of the two strains were 68.1 and 70.4 mol%, respectively. The 16S rRNA gene phylogeny showed that the novel strains formed two distinct sublines within the genus Microbacterium. Strain A18JL241T was most closely related to the type strain of Microbacterium tenebrionis KCTC 49593T (98.8 % sequence similarity), whereas strain Y20T formed a tight cluster with the type strain of Microbacterium schleiferi NBRC 15075T (99.0 %). The orthologous average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values with the type strains of related Microbacterium species were in the range of 74.1-89.1 % and 19.4-36.9 %, respectively, which were below the recognized thresholds of 95-96 % ANI and 70 % dDDH for species definition. Based on the results obtained here, it can be concluded that strains A18JL241T and Y20T represent two novel species of the genus Microbacterium, for which the names Microbacterium abyssi sp. nov. (type strain A18JL241T=JCM 33956T=MCCC 1A16622T) and Microbacterium limosum sp. nov. (type strain Y20T=JCM 33960T=MCCC 1A16747T) are proposed.

Lee SD, Yang HL, Kim IS. Four new Microbacterium species isolated from seaweeds and reclassification of five Microbacterium species with a proposal of Paramicrobacterium gen. nov. under a genome-based framework of the genus Microbacterium. Front Microbiol 2023; 14:1299950. [PMID: 38164402 PMCID: PMC10757982 DOI: 10.3389/fmicb.2023.1299950] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Accepted: 11/15/2023] [Indexed: 01/03/2024] Open
Abstract
The taxonomic relationships of 10 strains isolated from seaweeds collected from two beaches in Republic of Korea were studied by sequencing and analyses of 16S rRNA genes and whole genomes. For the construction of a more reliable and robust 16S rRNA gene phylogeny, the authentic and nearly complete 16S rRNA gene sequences of all the Microbacterium type strains were selected through pairwise comparison of the sequences contained in several public databases including the List of Prokaryotic names with Standing in Nomenclature (LPSN). The clustering of the ten study strains into five distinct groups was apparent in this single gene-based phylogenetic tree. In addition, the 16S rRNA gene sequences of a few type strains were shown to be incorrectly listed in LPSN. An overall phylogenomic clustering of the genus Microbacterium was performed with a total of 113 genomes by core genome analysis. As a result, nine major (≥ three type strains) and eight minor (two type strains) clusters were defined mostly at gene support index of 92 and mean intra-cluster OrthoANIu of >80.00%. All of the study strains were assigned to a Microbacterium liquefaciens clade and distributed further into four subclusters in the core genome-based phylogenetic tree. In vitro phenotypic assays for physiological, biochemical, and chemotaxonomic characteristics were also carried out with the ten study strains and seven closely related type strains. Comparison of the overall genomic relatedness indices (OGRI) including OrthoANIu and digital DNA-DNA hybridization supported that the study strains constituted four new species of the genus Microbacterium. In addition, some Microbacterium type strains were reclassified as members of preexisting species. Moreover, some of them were embedded in a new genus of the family Microbacteriaceae based on their distinct separation in the core genome-based phylogenetic tree and amino acid identity matrices. Based on the results here, four new species, namely, Microbacterium aurugineum sp. nov., Microbacterium croceum sp. nov., Microbacterium galbinum sp. nov., and Microbacterium sufflavum sp. nov., are described, along with the proposal of Paramicrobacterium gen. nov. containing five reclassified Microbacterium species from the "Microbacterium agarici clade", with Paramicrobacterium agarici gen. nov., comb. nov. as the type species.

Abstract
The Gram-positive, nonmotile, rod-shaped bacterium EF45044T was isolated from a hot spring in Chungju, South Korea. The strain was able to grow at concentrations of 0‒5% (w/v) NaCl, at pH 6.0‒10.0 and in the temperature range of 18‒50 °C. Strain EF45044T showed the highest 16S rRNA gene sequence similarity (98.2%) with Microbacterium ketosireducens DSM 12510T, and the digital DNA‒DNA hybridization (dDDH), average amino acid identity (AAI), and average nucleotide identity (ANI) values were all lower than the accepted species threshold. Strain EF45044T contained MK‒12 and MK‒13 as the predominant respiratory quinones and anteiso‒C17:0, anteiso‒C15:0, and iso‒C16:0 as the major fatty acids. Diphosphatidylglycerol, phosphatidylglycerol, and glycolipid were detected as the major polar lipids. The cell-wall peptidoglycan contained ornithine. The DNA G + C content was 71.4 mol%. Based on the polyphasic data, strain EF45044T (= KCTC 49703T) presents a novel species of the genus Microbacterium, for which the name Microbacterium neungamense sp. nov. is proposed.

Abstract
A Gram-stain-positive, strictly aerobic, polar flagellated, short rod-shaped bacterium, designated DFW100M-13T, was isolated from gut of the larva of Protaetia brevitarsis seulensis collected from Wanju-gun, South Korea. The growth range of NaCl concentration was 0–3 % (w/v) (optimally 0 % (w/v)), the temperature range for growth was 10–40 °C (optimally 28–30 °C), and the pH range for growth was pH 6.0–9.0 (optimally pH 7.0–8.0). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain DFW100M-13T had a high sequence similarity to members of the genus
Microbacterium
, having the highest similarity with
Microbacterium luticocti
DSM 19459T (97.7 %),
Microbacterium rhizosphaerae
CHO1T (97.1 %), and
Microbacterium immunditiarum
SK 18T (97.0 %), and formed a distinct lineage with
Microbacterium luticocti
DSM 19459T within the genus
Microbacterium
. A phylogenetic tree based on house-keeping genes also showed the result similar to the 16S rRNA gene-based tree. The main respiratory quinone (>10 %) was MK-11, MK-12 and MK-10, and the predominant cellular fatty acids (>10 %) were iso-C16 : 0, anteiso-C17 : 0 and anteiso-C15 : 0. The polar lipids were composed of diphosphatidylglycerol, phosphatidylglycerol, an inidentified glycolipid and an unidnetified lipid. The peptidoglycan type was supposed to be the B2ß with amino acids d-alanine, d-glutamic acid, glycine, l-homoserine and d-ornithine. The genomic DNA G+C content was 68.0 mol%. Based on the polyphasic taxonomic data, strain DFW100M-13T is considered to represent a novel species, for which the name Microbacterium protaetiae sp. nov. is proposed. The type strain is DFW100M-13T (=KACC 19323T=NBRC 113120T).

Abstract
Two strains of Gram-stain-positive, aerobic, non-spore-forming, non-motile, rod-shaped bacteria (designated dk512T and dk508) were isolated from the faeces of Tibetan gazelle (Procapra picticaudata) collected from the Qinghai-Tibet Plateau, PR China. The 16S rRNA gene sequences of the strains showed the highest identity to Microbacterium saccharophilum K-1T (98.0 and 97.9 % similarity, respectively). The phylogenetic analysis based on 16S rRNA gene sequences revealed that dk512T and dk508 were members of the genus Microbacterium, and most closely related to strains Microbacterium mitrae M4-8T and Microbacterium hatanonis FCC-01T. The strains grew optimally on brain-heart infusion (BHI) agar with 5.0 % (v/v) sheep blood at 30 °C, pH 7.0 and with 1.0 % (w/v) NaCl. The genome of type strain dk512T was 3.8 Mb with a G+C content of 70.6 mol%. The average nucleotide identity and digital DNA-DNA hybridization values between strain dk512T and previously characterized Microbacterium species were <95 and <70 %, respectively. In strain dk512T, the detected primary cellular fatty acids were anteiso-C15 : 0 and anteiso-C17 : 0, the main respiratory quinones were MK-9 (37.9 %) and MK-10 (35.7 %), and the polar lipids included diphosphatidylglycerol, phosphatidylglycerol and three unidentified glycolipids. The major cell-wall sugars were rhamnose, ribose and galactose. Alanine, glutamic acid, glycine and ornithine were in the cell-wall peptidoglycan. Based on phenotypic data and phylogenetic inference, these two strains represent a novel species of the genus Microbacterium, named here as Microbacterium wangchenii sp. nov, where dk512T is designated the type strain (=CGMCC 1.16590T=JCM 33494T=KCTC 49313T).

Abstract
A Gram-stain-positive, aerobic, non-motile, short-rod shaped actinobacterium, designated THG-T2.14T, was isolated from soil sampled from the rhizosphere of mugunghwa. Growth occurred at 10-40 °C (optimum 30 °C), at pH 5.0-10.0 (optimum 7.0) and at 0-7.0 % NaCl (optimum 3.0 %). Based on 16S rRNA gene sequence analysis, the nearest phylogenetic neighbours of strain THG-T2.14T were identified as Microbacterium yannicii DSM 23203T (98.8 %), Microbacterium trichothecenolyticum DSM 8608T (98.8 %), Microbacterium arthrosphaerae DSM 22421T (98.7 %) and Microbacterium jejuense KACC 17124T (98.4 %). The major fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, one unidentified lipid, two unidentified phospholipids and two unidentified phosphoglycolipids. The menaquinones were MK-12, and MK-13. The major polyamine was spermidine. The peptidoglycan contained ornithine, alanine, glycine, homoserine and glutamic acid. The diagnostic diamino acid was ornithine. The acyl type of the muramic acid was glycolyl. The whole-cell sugars were rhamnose, ribose, galactose, arabinose, xylose and glucose. The DNA G+C content of strain THG-T2.14T was 71.2 mol%. The DNA-DNA relatedness between strain THG-T2.14T and its closest reference strains were significantly lower than the threshold value of 70 %. On the basis of the phylogenetic analysis, chemotaxonomic data, physiological characteristics and DNA-DNA hybridization data, strain THG-T2.14T represents a novel species of the genus Microbacterium, for which the name Microbacterium hibisci sp. nov. is proposed. The type strain is THG-T2.14T (=KACC 18931T=CCTCC AB 2016180T).
