Strong Aromatic Chinese Liquor

A novel mesophilic, aerotolerant anaerobic bacterium, designated JN-18T, was isolated from the pit mud of a strong aromatic Chinese liquor. According to a 16S rRNA gene sequence analysis, it had the highest sequence similarity to Aminipila butyrica DSM 103574T (95.69%). The G+C content of its genomic DNA was 43.39 mol%. The cells were Gram-stain-negative, slightly curved rods with flagella. Optimum growth was observed at 37 °C, pH 6.5 and without extra addition of NaCl. Strain JN-18Tutilized amino acids (l-alanine, l-arginine, l-asparagine, l-lysine, l-methionine, l-serine and l-threonine), malate and pyruvate, and used l-arginine and l-lysine to produce acetate, butyrate, H2, and CO2. The major cellular fatty acids of strain JN-18T were C14:0, C16:0 DMA and C18:1 cis-9 DMA. The carbohydrate composition of the cell wall predominantly included galactose, glucose and rhamnose. Based on its phylogenetic, phenotypic, physiological and biochemical characteristics, strain JN-18T was classified as a representative of a novel species within the genus Aminipila , for which the name Aminipila luticellarii sp. nov. is proposed. The type strain is JN-18T (=CCAM 412T=JCM 39126T).

Type Strains

A Gram-staining-negative, non-motile, catalase- and oxidase-positive strain, designated CCNWSP36-1T, was isolated from the nodule surface of soybean [Glycine max (L.) Merrill] cultivar Zhonghuang 13. The 16S rRNA gene sequence analysis clearly showed that the isolate represented a member of the genus Sphingobacterium . On the basis of pairwise comparisons of 16S rRNA gene sequences, strain CCNWSP36-1T showed 96.8 % similarity to Sphingobacterium nematocida CCTCC AB 2010390T and less than 95.2 % similarity to other members of the genus Sphingobacterium . Growth of strain CCNWSP36-1T occurred at 10–40 °C and at pH 5.0–9.0. The NaCl range (w/v) for growth was 0–4 %. The predominant isoprenoid quinone was MK-7. The polar lipids were phosphatidylethanolamine and several unidentified polar lipids. Sphingolipid was present. The major fatty acids were iso-C15 : 0 and summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c). The G+C content of the genomic DNA was 41.1 mol%. As the physiological and biochemical characteristics of strain CCNWSP36-1T and the type strains of its closest phylogenetic neighbours showed clear differences, a novel species, Sphingobacterium yanglingense, is proposed. The type strain is CCNWSP36-1T ( = ACCC 19328T = JCM 30166T).

Faecal Samples

Four strains (9CBEGH2T, 9BBH35, 6BBH38 and 6EGH11) of Gram-stain-positive, obligately anaerobic, rod-shaped bacteria were isolated from faecal samples from healthy Japanese humans. The results of 16S rRNA gene sequence analysis indicated that the four strains represented members of the family Erysipelotrichaceae and formed a monophyletic cluster with ‘ Absiella argi ’ strain N6H1-5 (99.4% sequence similarity) and Eubacterium sp. Marseille-P5640 (99.3 %). Eubacterium dolichum JCM 10413T (94.2 %) and Eubacterium tortuosum ATCC 25548T (93.7 %) were located near this monophyletic cluster. The isolates, 9CBEGH2T, ‘ A. argi ’ JCM 30884 and Eubacterium sp. Marseille-P5640 shared 98.7–99.1% average nucleotide identity (ANI) with each other. Moreover, the in silico DNA–DNA hybridization (DDH) values among three strains were 88.4–90.6%, indicating that these strains represent the same species. Strain 9CBEGH2T showed 21.5–24.1 % in silico DDH values with other related taxa. In addition, the ANI values between strain 9CBEGH2T and other related taxa ranged from 71.2 % to 73.5 %, indicating that this strain should be considered as representing a novel species on the basis of whole-genome relatedness. Therefore, we formally propose a novel name for ‘ A. argi ’ strains identified because the name ‘ A. argi ’ has been effectively, but not validly, published since 2017. On the basis of the collected data, strain 9CBEGH2T represents a novel species of a novel genus, for which the name Amedibacterium intestinale gen. nov., sp. nov. is proposed. The type strain of A. intestinale is 9CBEGH2T (=JCM 33778T=DSM 110575T).

Pairwise Sequence Similarity

A novel Gram-negative, rod-shaped, non-motile, non-sporulating bacterium, designated strain K1T, was isolated from an estuarine water sample collected from Kochi, Kerala, India. Colonies on marine agar were circular, 2.0–2.5 mm in diameter, shiny, yellow, translucent and convex with entire margins. Strain K1T was negative for ornithine decarboxylase, lysine decarboxylase, nitrate reduction and H2S production. The fatty acids were dominated by iso-branched components with a high abundance of iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH; MK-6 (64 %) and MK-7 (34 %) were found as major respiratory quinones; and phosphatidylethanolamine, two unidentified aminolipids, four unidentified phospholipids and two unidentified lipids were major polar lipids. The DNA G+C content of strain K1T was 46.1 mol%. 16S rRNA gene sequence analysis indicated that strain K1T was related most closely to the type strain of Zhouia amylolytica (pairwise sequence similarity of 93.0 %). Phylogenetic analysis showed that strain K1T formed a distinct branch within the family Flavobacteriaceae and clustered with the clade comprising species of the genera Zhouia , Coenonia and Capnocytophaga , being phylogenetically most closely related to the type strain of Zhouia amylolytica at a distance of 9.2 % (90.8 % similarity). Other species of the genera within the same clade were related to strain K1T at distances of 15.0–23.1 %. Based on phenotypic and chemotaxonomic characteristics and on phylogenetic inference, strain K1T is considered to represent a novel species of a new genus in the family Flavobacteriaceae , for which the name Imtechella halotolerans gen. nov., sp. nov. is proposed. The type strain of Imtechella halotolerans is K1T ( = MTCC 11055T = JCM 17677T).

A Gram-stain-negative, rod-shaped, orange-coloured, catalase- and oxidase-positive, non-motile bacterium, designated strain 92VT, was isolated from the marine sponge Amphilectus fucorum, collected from Lough Hyne, County Cork, Ireland. 16S rRNA gene sequence analysis revealed that strain 92VT clustered with members of the family Flavobacteriaceae , the closest member being Aquimarina latercula NCIMB 1399T, with a gene sequence similarity of 97.5 %. Strain 92VT required seawater for growth with optimal growth occurring at 25 °C, at pH 6–7 and with 3 % (w/v) NaCl. MK-6 was the sole respiratory quinone present and the major fatty acids were iso-C17 : 0 3-OH, iso-C15 : 0, iso-C17 : 1ω9c and iso-C15 : 0 3-OH. The DNA G+C content was 36.1 mol%. Combined phenotypic differences and phylogenetic analysis indicate that strain 92VT represents a novel species of the genus Aquimarina , for which the name Aquimarina amphilecti sp. nov. is proposed. The type strain is 92VT ( = NCIMB 14723T = DSM 25232T).

A Gram-positive rod, designated 01-Gi-001T, was isolated from a wall colonized with moulds. The 16S rRNA gene sequence analysis clearly showed that the isolate belonged to the genus Microbacterium . On the basis of pairwise comparisons of 16S rRNA gene sequences, strain 01-Gi-001T was most closely related to Microbacterium hydrocarbonoxydans DSM 16089T (98.9 % sequence similarity), Microbacterium profundi Shh49T (98.7 %), Microbacterium phyllosphaerae DSM 13468T (98.3 %) and Microbacterium foliorum DSM 12966T (98.1 %). The diagnostic diamino acid of the peptidoglycan was ornithine. The major menaquinones detected were MK-13 and MK-12. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, one unknown phospholipid and one unknown glycolipid. The major fatty acids were anteiso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0, which were in agreement with those reported for other members of the genus Microbacterium . Physiological and biochemical characteristics and DNA–DNA relatedness between strain 01-Gi-001T and the type strains of its closest phylogenetic neighbours showed clear differences. For this reason, strain 01-Gi-001T ( = DSM 22178T = CCM 7640T) is proposed as the type strain of a novel species, Microbacterium murale sp. nov.

Strains of the recently proposed species Bacteroides chinchillae share more than 99.4 % 16S rRNA gene sequence similarity with the type strain of Bacteroides sartorii although these two species do not appear to be similar from their published descriptions. The aim of this study was to perform phenotypic and genetic analyses of both species to clarify their taxonomic position. B. chinchillae JCM 16497T exhibited high hsp60 gene sequence similarity with B. sartorii JCM 17136T (100 %) as well as B. chinchillae JCM 16498 (100 %). The hsp60 gene sequence analysis and levels of DNA–DNA relatedness observed demonstrated B. sartorii JCM 17136T, B. chinchillae JCM 16497T, and B. chinchillae JCM 16498 are members of a single species. Based on these data, we propose Bacteroides chinchillae as a later heterotypic synonym of Bacteroides sartorii . An emended description of B. sartorii is provided.

Utilization Patterns

An alphaproteobacterium, strain Dia-1T, was isolated from algae-dominated biofilms on stones from the littoral zone of Lake Constance, Germany. This bacterium was isolated after initial enrichment in spent medium obtained after growth of a diatom culture. Numerous sugars and some organic acids and alcohols served as growth substrates. The bacterium grew slowly, was strictly aerobic but microaerophilic, and did not grow in cultures shaken under air. 16S rRNA gene sequence analysis indicated that strain Dia-1T was distantly related to representatives of the genera Azospirillum (90–91 % sequence similarity), Skermanella (88–89 %), Rhodocista (87–88 %) and Dongia (88–89 % sequence similarity). Based on this sequence comparison, on phenotypic characterization including substrate utilization patterns, and comparison of cellular fatty acids, quinones, polar lipids and polyamines, this isolate was found to be substantially different from the genera mentioned above. On the basis of these results, a novel genus and species is proposed for this strain. The name Elstera litoralis gen. nov., sp. nov. is suggested, with strain Dia-1T ( = DSM 19532T = LMG 24234T) as the type strain of the type species.

A Gram-stain-negative, aerobic, non-motile and rod-shaped marine bacterium, CW2-9T, was isolated from algae collected from Fujian Province in PR China. 16S rRNA gene sequence analysis showed that this strain was affiliated with the genus Tamlana in the family Flavobacteriaceae of the class Flavobacteriia and was very similar to the type strain Tamlana sedimentorum MCCC 1A10799T (96.3 % sequence similarity). The whole genome of strain CW2-9T comprised 3 997 513 bp with a G+C content of 34.3 mol%. The average nucleotide identity value between strain CW2-9T and T. sedimentorum MCCC 1A10799T was 73.8 %. Growth was observed from 15 to 40 °C (optimum, 30 °C), at pH from pH 5.0 to 10.0 (pH 8.0) and in the presence of 0–4 % (w/v) NaCl (0–1 %). The major fatty acids (>10 % of the total) were iso-C15 : 0, iso G-C15 : 1, iso-C17 : 0 3-OH and anteiso-C15 : 0. The predominant menaquinone was MK-6. The combined phylogenetic, physiological and chemotaxonomic data indicate that strain CW2-9T represents a novel species in the genus Tamlana , for which the name Tamlana fucoidanivorans sp. nov. is proposed. The type strain is CW2-9T (=CICC 24749T=KCTC 72389T).

Ten representative actinobacterial strains isolated from marine sediments collected worldwide were studied to determine their taxonomic status. The strains were previously identified as members of the genus Salinispora and shared >99 % 16S rRNA gene sequence similarity to the three currently recognized Salinispora species. Comparative genomic analyses resulted in the delineation of six new species based on average nucleotide identity and digital DNA–DNA hybridization values below 95 and 70 %, respectively. The species status of the six new groups was supported by a core-genome phylogeny reconstructed from 2106 orthologs detected in 118 publicly available Salinispora genomes. Chemotaxonomic and physiological studies were used to complete the phenotypic characterization of the strains. The fatty acid profiles contained the major components iso-C16 : 0, C15 : 0, iso-17 : 0 and anteiso C17 : 0. Galactose and xylose were common in all whole-sugar patterns but differences were found between the six groups of strains. Polar lipid compositions were also unique for each species. Distinguishable physiological and biochemical characteristics were also recorded. The names proposed are Salinispora cortesiana sp. nov., CNY-202T (=DSM 108615T=CECT 9739T); Salinispora fenicalii sp. nov., CNT-569T (=DSM 108614T=CECT 9740T); Salinispora goodfellowii sp. nov., CNY-666T (=DSM 108616T=CECT 9738T); Salinispora mooreana sp. nov., CNT-150T (=DSM 45549T=CECT 9741T); Salinispora oceanensis sp. nov., CNT-138T (=DSM 45547T=CECT 9742T); and Salinispora vitiensis sp. nov., CNT-148T (=DSM 45548T=CECT 9743T).

Two Gram-positive, moderately thermophilic, endospore-forming, rod-shaped, motile bacteria, designated PDF25T and PDF30, were isolated from Karakoc hot spring in the province of Izmir, Turkey, and were characterized in order to determine their phylogenetic positions. 16S rRNA gene sequence analysis revealed that the two strains belonged to the genus Brevibacillus ; strain PDF25T showed highest sequence similarity to strain PDF30 (99.4 %) and Brevibacillus thermoruber DSM 7064T (98.5 %). The major fatty acids of strain PDF25T were iso-C15 : 0 (39.30 %), anteiso-C15 : 0 (26.10 %) and iso-C16 : 0 (14.75 %). Polar lipid analysis revealed diphosphatidylglycerol, phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, and a variety of unidentified aminophospholipids, phospholipids and aminolipids. The major isoprenoid quinone was MK-7. The G+C content of the genomic DNA was 56.09 mol%. DNA–DNA hybridization experiments revealed 58 % relatedness between strain PDF25T and B. thermoruber DSM 7064T. Based on these data, the two strains are considered to represent a novel species of the genus Brevibacillus , for which the name Brevibacillus aydinogluensis sp. nov. is proposed. The type strain is PDF25T ( = DSM 24395T = LMG 26289T).
