Abstract
A microaerophilic, Gram-negative, motile, and spiral-shaped bacterium, designated Y-M2T, was isolated from oil sludge of Shengli oil field. The optimal growth condition of strain Y-M2T was at 25 °C, pH 7.0, and in the absence of NaCl. The major polar lipid was phosphatidylethanolamine. The main cellular fatty acid was iso-C17 : 0 3-OH. It contained Q-9 and Q-10 as the predominant quinones. The DNA G+C content was 68.1 mol%. Strain Y-M2T showed the highest 16S rRNA gene sequence similarity to Telmatospirillum siberiense 26-4bT (91.1 %). Phylogenetic analyses based on 16S rRNA gene and genomes showed that strain Y-M2T formed a distinct cluster in the order Rhodospirillales. Genomic analysis showed that Y-M2T possesses a complete nitrogen-fixation cluster which is phylogenetically close to that of methanogene. The nif cluster, encompassing the nitrogenase genes, was found in every N2-fixing strain within the order Rhodospirillales. Phylogeny, phenotype, chemotaxonomy, and genomic results demonstrated that strain Y-M2T represents a novel species of a novel genus in a novel family Oleispirillaceae fam. nov. in the order Rhodospirillales, for which the name Oleispirillum naphthae gen. nov., sp. nov. was proposed. The type strain is Y-M2T (=CCAM 827T=JCM 34765T).

Abstract
A microaerophilic, mesophilic, chemoorganoheterotrophic bacterium, designated Y-P2T, was isolated from oil sludge enrichment in China. Cells of the strain were Gram-stain-negative, non-motile, non-spore-forming, rod-shaped or slightly curved with 0.8-3.0 µm in length and 0.4-0.6 µm in diameter. The strain Y-P2T grew optimally at 25 °C (range from 15 to 30 °C) and pH 7.0 (range from pH 6.0 to 7.5) without NaCl. The major cellular fatty acids were C16:0, summed feature 3 (C16:1 ω7c and/or C16:1 ω6c), summed feature 8 (C18:1 ω7c and/or C18:1 ω6c). The main polar liquids of strain Y-P2T comprised phosphatidylethanolamine (PE) and phosphatidylglycerol (PG). The respiratory quinone was Q-10. Acetate and H2 were the fermentation products of glucose. The DNA G + C content was 66.0%. Strain Y-P2T shared the highest 16S rRNA gene sequence similarity (90.3-90.6%) with species within Oceanibaculum of family Thalassobaculaceae in Rhodospirillales. Phylogenetic analyses based on 16S rRNA gene sequences and genomes showed that strain Y-P2T formed a distinct evolutionary lineage within the order Rhodospirillales. On the basis of phenotypic, phylogenetic and phylogenomic data, we propose that strain Y-P2T represents a novel species in a novel genus, for which Shumkonia mesophila gen. nov., sp. nov., within a new family Shumkoniaceae fam. nov. The type strain is Y-P2T (= CCAM 826 T = JCM 34766 T).

Microorganisms 2023; 11:2463. [PMID: 37894121 PMCID: PMC10608839 DOI: 10.3390/microorganisms11102463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 09/25/2023] [Accepted: 09/26/2023] [Indexed: 10/29/2023] Open
Abstract
A novel Gram-staining negative, strictly aerobic, rod-shaped, and non-motile bacterium, designated strain 10Alg 79T, was isolated from the red alga Ahnfeltia tobuchiensis. A phylogenetic analysis based on 16S rRNA gene sequences placed the novel strain within the family Roseobacteraceae, class Alphaproteobacteria, phylum Pseudomonadota, where the nearest neighbor was Shimia sediminis ZQ172T (97.33% of identity). However, a phylogenomic study clearly showed that strain 10Alg 79T forms a distinct evolutionary lineage at the genus level within the family Roseobacteraceae combining with strains Aquicoccus porphyridii L1 8-17T, Marimonas arenosa KCTC 52189T, and Lentibacter algarum DSM 24677T. The ANI, AAI, and dDDH values between them were 75.63-78.15%, 67.41-73.08%, and 18.8-19.8%, respectively. The genome comprises 3,754,741 bp with a DNA GC content of 62.1 mol%. The prevalent fatty acids of strain 10Alg 79T were C18:1 ω7c and C16:0. The polar lipid profile consisted of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, an unidentified aminolipid, an unidentified phospholipid and an unidentified lipid. A pan-genome analysis showed that the unique part of the 10Alg 79T genome consists of 13 genus-specific clusters and 413 singletons. The annotated singletons were more often related to transport protein systems, transcriptional regulators, and enzymes. A functional annotation of the draft genome sequence revealed that this bacterium could be a source of a new phosphorylase, which may be used for phosphoglycoside synthesis. A combination of the genotypic and phenotypic data showed that the bacterial isolate represents a novel species and a novel genus, for which the name Rhodoalgimonas zhirmunskyi gen. nov., sp. nov. is proposed. The type strain is 10Alg 79T (=KCTC 72611T = KMM 6723T).

Abstract
A novel Gram-staining negative, strictly aerobic, rod-shaped, and non-motile bacterium, designated strain 9Alg 56T, was isolated from the red alga Tichocarpus crinitus. The phylogenetic analysis based on 16S rRNA gene sequences placed the novel strain within the family Rhodobacteraceae, the order Rhodobacterales, the class Alphaproteobacteria, the phylum Pseudomonadota. The nearest neighbors of the new strain were Pontivivens insulae KCTC 42458T, Oceanibium sediminis KCTC 62076T, Halovulum dunhuangense YYQ-30T and Monaibacterium marinum C7T with 16S rRNA gene sequence similarity of 94.7, 94.4%, 93.1 and 92.7%, respectively. The AAI/ANI/dDDH values between 9Alg 56T and the five species of the closest genera (Pontivivens, Oceanibium, Halovulum, Monaibacterium, and 'Oceanomicrobium') were 58.63-63.91%/ 75.91-77.37%/ 19.3-20.4%. The prevalent fatty acids of strain 9Alg 56T were C18:1 ω7c, C18:0 and C14:0 3-OH. The polar lipid profile consisted of phosphatidylethanolamine, phosphatidylglycerol, phosphatidic acid, phosphatidylcholine, and two unidentified lipids. The DNA G+C content of strain 9Alg 56T was 61.5 mol%. A combination of the genotypic and phenotypic data showed that the algal isolate represents a novel genus and species, for which the name Algicella marina gen. nov., sp. nov. is proposed. The type strain is 9Alg 56T (= KCTC 72005T = KMM 6775T).

Abstract
A polyphasic taxonomic approach was used to characterize a Gram-stain-negative bacterium, designated strain CC-CFT640T, isolated from vineyard soil sampled in Taiwan. Cells of strain CC-CFT640T were aerobic, non-motile, nitrate-reducing rods. Test results were positive for catalase, oxidase and proteinase activities. Optimal growth occurred at 30 °С and pH 7. Strain CC-CFT640T showed highest 16S rRNA gene sequence similarity to members of the genus Enhydrobacter (90.0 %, n=1) followed by Hypericibacter (89.4-90.0 %, n=2), Reyranella (88.8-89.8 %, n=5) and Nitrospirillum (89.2-89.4 %, n=2), and formed a distinct phyletic lineage distantly associated with the clade that predominately accommodated Reynerella species. The DNA G+C composition of the genome (2.1 Mb) was 67.9 mol%. Genes involved in the reduction of nitrate to nitrite, nitric oxide and nitrous oxide were found. In addition, genes encoding dissimilatory nitrate reduction to ammonia, ammonium transport and ammonium assimilation were also detected. Average nucleotide identity values were 73.3 % (n=1), 74.0-74.6 % (n=2), 67.5-68.3 % (n=2) when compared within the type strains of the genera Enhydrobacter, Reyranella and Niveispirillum, respectively. The dominant cellular fatty acids (>5 %) included C16 : 0, iso-C17 : 1 ω10c, C19 : 0 cyclo ω8c, C18 : 1 2-OH and C18 : 1 ω7c/C18 : 1 ω6c. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, three unidentified aminolipids, three unidentified phospholipids and an unidentified aminophospholipid. The major respiratory quinone was ubiquinone 10 and the major polyamine was spermidine. Based on its distinct phylogenetic, phenotypic and chemotaxonomic traits together with results of comparative 16S rRNA gene sequencing, digital DNA-DNA hybridization, average nucleotide identity and phylogenomic placement, strain CC-CFT640T is considered to represent a novel genus and species of the family Rhodospirillaceae, for which the name Vineibacter terrae gen. nov., sp. nov. is proposed. The type strain is CC-CFT640T (=BCRC 81219T=JCM 33507T).

Abstract
The Gram-stain-negative, strictly aerobic, curved-to-spiral rod-shaped bacterial strain, designated KN72T, was isolated from the Caroline Seamounts in the Pacific Ocean. Phylogenetic analysis of 16S rRNA gene sequences revealed that strain KN72T was a member of the family Rhodospirillaceae and formed a distinct lineage. Strain KN72T contained ubiquinone-10 as the major respiratory quinone. The polar lipid profiles contained phosphatidylethanolamine, phosphatidylglycerol, one aminolipid and three phospholipids. The predominant cellular fatty acids were C16:0 and summed feature 8 (comprising C18:1ω7c/C18:1ω6c). The strain KN72T displayed highest 16S rRNA gene sequence similarities with Hwanghaeella grinnelliae Gri0909T (92.3%), Marivibrio halodurans ZB80T (91.0%) and Aestuariispira insulae AH-MY2T (90.1%). The DNA G+C content of strain KN72T was 61.1%. Collectively, based on phenotypic, chemotaxonomic, phylogenetic and genomic evidence presented, strain KN72T represents a novel species of a novel genus of the family Rhodospirillaceae, for which the name Pacificispira spongiicola gen. nov., sp. nov. is proposed. The type strain is KN72T (= CGMCC 1.17142T = KCTC 72429T).

Abstract
A bacterial strain, designated 5J-6T, was isolated from soil in Cheongnyeongpo, Republic of Korea. Cells were Gram-stain-positive, strictly aerobic, and motile rods and their catalase and oxidase activities were positive. Strain 5J-6T grew at 10-30 °C, pH 6.0-9.0, and 0-0.8% (w/v) NaCl concentration, with optimum growth at 25 °C, pH 6.5, and 0.4% NaCl concentration. Anteiso-C15:0 and iso-C16:0 were detected as the predominant fatty acids and menaquinone-7 was the sole isoprenoid quinone detected. Strain 5J-6T contained phosphatidylethanolamine, phosphatidylglycerol and an unidentified phospholipid as major polar lipids. The peptidoglycan belonged to the type A1γ meso-diaminopimelic acid. The G+C content of the genomic DNA calculated from the whole genomic sequence was 46.1 mol%. Phylogenetic analysis of strain 5J-6T based on 16S rRNA gene sequences placed the isolate into a member of the genus Paenibacillus. Sequence similarity analysis of 16S rRNA gene sequences revealed that strain 5J-6T was most closely related to Paenibacillus aceris KUDC4121T and Paenibacillus chondroitinus DSM 5051T with 98.76% and 98.42% similarities, respectively. Average nucleotide identity and in silico DNA-DNA hybridization values between strain 5J-6T and the type strain of P. aceris were 83.97% and 28.60%, respectively. Based on the phylogenetic and phenotypic characteristics and genomic data, strain 5J-6T could be considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus silvestris sp. nov. is proposed. The type strain is 5J-6T (= KACC 21430T = JCM 33812T).
