Abstract
An orange-golden iridescent culture, designated A1X5R2T, was isolated from a compost soil suspension which was amended with
Micrococcus luteus
NCTC 2665T culture supernatant. The cells were non-motile, Gram-stain-negative, 0.4–0.5 µm wide and 0.7–1.4 µm long. The 16S rRNA-based phylogenetic and whole-genome analyses revealed that strain A1X5R2T forms a distinct lineage within the family
Sphingosinicellaceae
and is closely related to members of the genus
Sphingoaurantiacus
(
S. capsulatus
, 93.04 % similarity, and
S. polygranulatus
, 92.77 %). The organism grew at 22–47 °C (optimal at 37 °C), salinity <3 % (optimal at 1.5 %) and at pH 7. The major respiratory quinone was ubiquinone-10, but a small quantity of ubiquinone-9 was also detected The major polyamine was homospermidine, but a small quantity of putrescine was also detected. The strain contained C18 : 1ω7c, C16 : 0, C16 : 1 ω7c and C18 : 0 as the major fatty acids. The main polar lipids were phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, phosphatidylinositol, sphingoglycolipid, diphosphatidylglycerol, two unidentified phospholipids and three unidentified amino lipids. The DNA G+C content was 64.9 mol%. According to the results of phylogenetic and phylogenomic analyses, as well as its physiological characteristics, strain A2X5R2T represents the type species of a novel genus within the family
Sphingosinicellaceae
. The name Pedomonas mirosovicensis gen. nov., sp. nov. is proposed, with the type strain being A1X5R2T (=NCCB 100839T=DSM 112829T).

Tahon G, Gök D, Lebbe L, Willems A. Description and functional testing of four species of the novel phototrophic genus Chioneia gen. nov., isolated from different East Antarctic environments. Syst Appl Microbiol 2021; 44:126250. [PMID: 34592543 DOI: 10.1016/j.syapm.2021.126250] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 09/02/2021] [Accepted: 09/03/2021] [Indexed: 10/20/2022]
Abstract
Seven Gram-negative, aerobic, non-sporulating, motile strains were isolated from terrestrial (R-67880T, R-67883, R-36501 and R-36677T) and aquatic (R-39604, R-39161T and R-39594T) East Antarctic environments (i.e. soil and aquatic microbial mats), between 2007 and 2014. Analysis of near-complete 16S rRNA gene sequences revealed that the strains potentially form a novel genus in the family Sphingomonadaceae (Alphaproteobacteria). DNA-DNA reassociation and average nucleotide identity values indicated distinction from close neighbors in the family Sphingomonadaceae and showed that the seven isolates form four different species. The main central pathways present in the strains are the glycolysis, tricarboxylic acid cycle and pentose phosphate pathway. The strains can use only a limited number of carbon sources and mainly depend on ammonia and sulfate as a nitrogen and sulfur source, respectively. The novel strains showed the potential of aerobic anoxygenic phototrophy, based on the presence of bacteriochlorophyll a pigments, which was corroborated by the presence of genes for all building blocks for a type 2 photosynthetic reaction center in the annotated genomes. Based on the results of phenotypic, genomic, phylogenetic and chemotaxonomic analyses, the strains could be assigned four new species in the novel genus Chioneia gen. nov. in the family Sphingomonadaceae, for which the names C. frigida sp. nov. (R-67880T, R-67883 and R-36501), C. hiemis sp. nov. (R-36677T), C. brumae sp. nov. (R-39161T and R-39604) and C. algoris sp. nov. (R-39594T) are proposed.

Abstract
Strain SZY PN-1 T, representing a novel Gram-negative, aerobic, non-motile, rod-shaped and yellow-pigmented bacterium, was isolated from a skin sample of a healthy Chinese male. Growth occurred at pH 6.0-8.0 (optimum, pH 7.0) and 10-37 ℃ (optimum, 30 ℃) with 0-1.0% (w/v) NaCl in R2A agar. Comparative analysis of the 16S rRNA gene sequences revealed that strain SZY PN-1 T shared high similarities with two invalid-published species, "Sandaracinobacter sibiricus" RB16-17 (97.1%) and "Sandaracinobacter neustonicus" JCM 30734 (96.6%), respectively. Phylogenetic analysis of 16S rRNA gene sequences together with protein-concatemer tree showed that SZY PN-1 T formed a separate branch within the family Sphingosinicellaceae. The DNA G + C content of the strain SZY PN-1 T was 65.0% (genome). The polar lipid profile included phosphatidylethanolamine, phosphatidylglycerol, two sphingoglycolipids, diphosphatidylglycerol, five unidentified glycolipids, and seven unidentified lipids. The predominant fatty acids (> 10.0%) were identified as C18:1 ω7c and/or C18:1 ω6c, C17:1 ω6c, C16:1 ω7c and/or C16:1 ω6c. The major respiratory quinone was Q-10. Based on the phenotypic and genotypic features, a novel genus and species, Sandaracinobacteroides hominis gen. nov., sp. nov. is proposed, with type strain SZY PN-1 T (= KCTC 82150 T = NBRC 114675 T).

Abstract
A novel Gram-stain-negative, rod-shaped, yellow bacterium, designated as LB1R16T, was isolated from the Laigu glacier on the Tibetan Plateau, PR China. Strain LB1R16T was catalase-positive, oxidase-negative and grew at 0-28 °C, pH 6.0-8.0 and in the absence of NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain LB1R16T belongs to the family Sphingosinicellaceae but formed an independent lineage. The highest level of 16S rRNA gene sequence similarities were found to Polymorphobacter arshaanensis DJ1R-1T (95.24 %), Sphingoaurantiacus capsulatus YLT33T (94.78 %) and Sandarakinorhabdus limnophila DSM 17366T (94.67 %). The genomic DNA G+C content was 68.8 mol%. The main cellular fatty acids were summed feature 8 (C18 : 1 ω7c/C18 : 1 ω6c), summed feature 3 (C16 : 1 ω7c/C16 : 1 ω6c), C16 : 0 and C12 : 0-OH. The respiratory quinone was ubiquinone-10. The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, one sphingoglycolipid, one unidentified aminolipid, one unidentified phospholipid and two unidentified polar lipids, which were different from the type strains of Polymorphobacter arshaanensis, Sphingoaurantiacus capsulatus and Sandarakinorhabdus limnophila. Based on a polyphasic approach, a novel species of a new genus, Glacieibacterium frigidum gen. nov., sp. nov., within the family Sphingosinicellaceae is proposed. The type strain is LB1R16T (=CGMCC 1.11941T=NBRC 113873T).

Abstract
Two bacterial strains SYSU G02173T and SYSU G03142 were isolated from hot springs in Tibet, China. Based on the results of nearly full-length 16S rRNA gene sequences and phylogenetic analyses, strains SYSU G02173T and SYSU G03142 were assigned to the family Sphingosinicellaceae, and were closest to Sandaracinobacter sibiricus RB16-17 T (96.04% and 96.12% similarity, respectively). Cells of the both new strains were observed to be motile rod-shape, Gram-staining negative. Growth occurred at pH 6-8 (optimal: pH 7.0) and 37-55 °C (optimal: 45 °C) with 0-1.0% (w/v) NaCl in T4 broth. The cells were found to be positive for oxidase and catalase activities. The major respiratory ubiquinone was Q-8. The major fatty acids were identified as summed feature 8 (C18:1 ω7c and/or C18:1 ω6c), C16:0, C14:0 2-OH. The major polar lipids were found to consist of sphingoglycolipid, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, one unidentified phospholipid, one unidentified glycolipid, three unidentified aminolipids and two unidentified polar lipids. The DNA G + C contents of strains SYSU G02173T and SYSU G03142 were 71.8%. The average nucleotide identity (ANI) value between strain SYSU G02173T and SYSU G03142 was 99.98%. The amino acid identity (AAI) values between them and their closely related species were below 66.14%. The isolates are characterized by aerobic growth, a yellow endocellular pigment and a higher optimum growth temperature. The results showed that strains SYSU G02173T and SYSU G03142 represent a novel species of a novel genus in the family Sphingomonadaceae, and thus the name Thermaurantiacus tibetensis (type strain SYSU G02173T = KCTC 72052 T = CGMCC 1.16680 T) is proposed.

Analysis of 1,000+ Type-Strain Genomes Substantially Improves Taxonomic Classification of Alphaproteobacteria. Front Microbiol 2020; 11:468. [PMID: 32373076 PMCID: PMC7179689 DOI: 10.3389/fmicb.2020.00468] [Citation(s) in RCA: 259] [Impact Index Per Article: 64.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Accepted: 03/04/2020] [Indexed: 11/13/2022] Open
Abstract
The class Alphaproteobacteria is comprised of a diverse assemblage of Gram-negative bacteria that includes organisms of varying morphologies, physiologies and habitat preferences many of which are of clinical and ecological importance. Alphaproteobacteria classification has proved to be difficult, not least when taxonomic decisions rested heavily on a limited number of phenotypic features and interpretation of poorly resolved 16S rRNA gene trees. Despite progress in recent years regarding the classification of bacteria assigned to the class, there remains a need to further clarify taxonomic relationships. Here, draft genome sequences of a collection of genomes of more than 1000 Alphaproteobacteria and outgroup type strains were used to infer phylogenetic trees from genome-scale data using the principles drawn from phylogenetic systematics. The majority of taxa were found to be monophyletic but several orders, families and genera, including taxa recognized as problematic long ago but also quite recent taxa, as well as a few species were shown to be in need of revision. According proposals are made for the recognition of new orders, families and genera, as well as the transfer of a variety of species to other genera and of a variety of genera to other families. In addition, emended descriptions are given for many species mainly involving information on DNA G+C content and (approximate) genome size, both of which are confirmed as valuable taxonomic markers. Similarly, analysis of the gene content was shown to provide valuable taxonomic insights in the class. Significant incongruities between 16S rRNA gene and whole genome trees were not found in the class. The incongruities that became obvious when comparing the results of the present study with existing classifications appeared to be caused mainly by insufficiently resolved 16S rRNA gene trees or incomplete taxon sampling. Another probable cause of misclassifications in the past is the partially low overall fit of phenotypic characters to the sequence-based tree. Even though a significant degree of phylogenetic conservation was detected in all characters investigated, the overall fit to the tree varied considerably.

Abstract
A pale yellow bacterial strain, designated JJ-A5T, was isolated form an agricultural soil from Jeju Island in Republic of Korea. Cells of the strain were Gram-stain-negative, motile, flagellated and rod-shaped. The strain grew at 15-30°C, pH 6.0-9.0, and in the presence of 0-1.5% (w/v) NaCl. Growth occurred on R2A, but not on Luria-Bertani agar, nutrient agar, trypticase soy agar and MacConkey agar. The strain utilized alachlor as a sole carbon source for growth. The strain JJ-A5T showed 16S rRNA gene sequence similarities lower than 95.4% with members of the family Sphingomonadaceae. Phylogenetic analysis showed that the strain belongs to the family Sphingomonadaceae and strain JJ-A5T was distinctly separated from established genera of this family. The strain contained Q-10 as dominant ubiquinone and spermidine as major polyamine. The predominant cellular fatty acids were summed feature 8 (C18:1ω7c and/or C18:1ω6c), summed feature 3 (C16:1ω7c and/or C16:1ω6c), 11-methyl C18:1ω7c, C16:0 and C14:0 2-OH. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid, and phosphatidylcholine. The DNA G + C content of the strain was 62.7 mol%. On the basis of the phenotypic, genomic and chemotaxonomic characteristics, strain JJ-A5T is considered to represent a novel genus and species within the family Sphingomonadaceae, for which the name Tardibacter chloracetimidivorans gen. nov., sp. nov. is proposed. The type strain of Tardibacter chloracetimidivorans is JJ-A5T (= KACC 19450T = NBRC 113160T).

Abstract
A Gram-negative bacterium, denoted JLT2012(T), was isolated from the surface water of the Pacific Ocean. This aerobic bacterium was rod shaped and devoid of flagella, displayed gliding motility, and grew in characteristic orange colonies. The bacterium contained ubiquinone Q-10 as the major respiratory quinone, and spermidine and spermine as the major polyamine compounds. The dominant fatty acids were C18:1ω7c and/or C18:1ω6c (34.7 %), C16:0 (21.3 %), and C18:0 (15.9 %), whereas the polar lipids consisted mainly of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, four sphingoglycolipids, and several unknown glycolipids. The G + C content DNA was found to be 65.5 mol%. Comparative 16S rRNA gene sequence analysis revealed that strain JLT2012(T) formed a distinct lineage within the genus Pacificimonas (formerly known as Pacificamonas) and shared the highest sequence similarity with the type strain of Pacificimonas flava JLT2015(T) (96.0 %). Data combined from different studies on the phenotypic, phylogenetic, and genomic characteristics indicated that strain JLT2012(T) is a representative of a novel species within Pacificimonas for which the name Pacificimonas aurantium sp. nov. (type strain JLT2012(T)=LMG 27361(T)=CGMCC 1.12399(T)) is proposed.
