During investigations of spoilage-associated meat microbiota, Pseudomonas isolates were found in two different laboratories showing highest similarities to Pseudomonas lactis DSM 29167T, Pseudomonas paralactis DSM 29164T and Pseudomonas azotoformans DSM 18862T based on 16S rRNA gene sequence comparisons. Phylogenetic analysis of the complete rpoB gene sequences of isolates B4-1T and SpeckC indicated a separate branch with 99.0 and 99.1 % identity, respectively, to their closest relative ( P. lactis DSM 29167T). Further phenotypic and chemotaxonomic characterizations, as well as average nucleotide identity (ANIb) values obtained from the draft genomes, revealed that these isolates could be considered as representing a novel species, with ANIb values of around 94 and 90 % with their closest relatives P. lactis and P. paralactis . Other related species showed ANIb values below 90 %, including Pseudomonas libanensis DSM 17149T, Pseudomonas synxantha DSM 18928T, Pseudomonas orientalis DSM 17489T, Pseudomonas veronii DSM 11331T and P. azotoformans DSM 18862T. Genome-to-genome distance calculations between B4-1T and its closest relative, P. lactis DSM 29167T, showed 62.6 % relatedness. The G+C contents of B4-1T and SpeckC were 59.8 and 59.9 mol%, respectively. The major cellular lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol; the major quinone was Q9. Based on these data, the new species Pseudomonas carnis sp. nov. is proposed, the type strain is B4-1T (=DSM 107652T=LMG 30892T); a second strain is SpeckC (=DSM 107651=LMG 30893).

Two Gram-stain-positive strains, c9Ua_26_MT and c11Ua_112_MT, were isolated from voided urine samples from two healthy women. Comparative 16S rRNA gene sequences demonstrated that these novel strains were members of the genus Limosilactobacillus . Phylogenetic analysis based on pheS gene sequences and core genomes showed that each strain formed a separated branch and are closest to Limosilactobacillus vaginalis DSM 5837T. The average nucleotide identity (ANI) and Genome-to-Genome Distance Calculator (GGDC) values between c9Ua_26_MT and the closest relative DSM 5837T were 90.7 and 42.9 %, respectively. The ANI and GGDC values between c11Ua_112_MT and the closest relative DSM 5837T were 91.2 and 45.0 %, and those among the strains were 92.9% and 51,0 %, respectively. The major fatty acids were C12 : 0 (40.2 %), C16 : 0 (26.7 %) and C18 : 1 ω9c (17.7 %) for strain c9Ua_26_MT, and C18 : 1 ω9c (38.0 %), C16 : 0 (33.3 %) and C12 : 0 (17.6 %) for strain c11Ua_112_MT. The genomic DNA G+C content of strains c9Ua_26_MT and c11Ua_112_MT was 39.9 and 39.7 mol%, respectively. On the basis of the data presented here, strains c9Ua_26_MT and c11Ua_112_MT represent two novel species of the genus Limosilactobacillus , for which the names Limosilactobacillus urinaemulieris sp. nov. (c9Ua_26_MT=CECT 30144T=LMG 31899T) and Limosilactobacillus portuensis sp. nov. (c11Ua_112_MT=CECT 30145T=LMG 31898T) are proposed.

Cells of bacterial strains 4 G-K06T and 4MSK11T, isolated from soil samples collected from monsoon evergreen broad-leaved forest of the Dinghushan Mountain (112° 31′ E 23° 10′ N), Guangdong Province, PR China, were Gram-stain-negative, aerobic, non-spore-forming, non-motile and rod-shaped. Strain 4 G-K06T grew at 10–37 °C, pH 3.5–7.5 and 0–3.5 % (w/v) NaCl; while 4MSK11T grew at 4–42 °C, pH 3.5–7.5 and 0–2.5 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed strain 4 G-K06T formed a clade with Dyella flagellata 4 M-K16T, Dyella acidisoli 4M-Z03T, Dyella humi DHG40T and Dyella nitratireducens DHG59T, while strain 4MSK11T formed a clade with Dyella caseinilytica DHOB09T and Dyella mobilis DHON07T, both within the genus Dyella . The result of the partial atpD, gyrB and lepA gene sequence analysis supported the conclusion based on 16S rRNA gene sequence analysis, which showed that these two strains represent two novel species of Dyella . The average nucleotide identity and digital DNA–DNA hybridization value for the whole genomes were 75.0–79.0 and 20.3–22.6 % between strains 4 G-K06T, 4MSK11T and those described Dyella species with genome sequences; while the DNA–DNA hybridization rates between strains 4 G-K06T, 4MSK11T and closely related Dyella species (without genome sequence) were 29.5–41.8 %. The major cellular fatty acids of these two strains were iso-C15 : 0, iso-C16 : 0 and iso-C17 : 1 ω9c, while the major polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and several unidentified phospholipids and aminophospholipids. The only ubiquinone of these two strains was ubiquinone-8. The DNA G+C contents of 4 G-K06T and 4MSK11T were 60.4 and 61.3 mol%, respectively. On the basis of the evidence presented here, strains 4 G-K06T and 4MSK11T represent two novel species of the genus Dyella , for which the names Dyella monticola sp. nov. (type strain 4 G-K06T=LMG 30268T=GDMCC 1.1188T) and Dyella psychrodurans sp. nov. (type strain 4MSK11T=KCTC 62280T=GDMCC 1.1185T) are proposed.

The taxonomic position of a novel actinomycete, strain RC 1831T, isolated from the sediment of a fish dumping yard at Barkul village near Chilika Lake, Odisha, India, was determined by a polyphasic approach. Based on morphological and chemotaxonomic characteristics the isolate was determined to belong to the genus Streptomyces . The phylogenetic tree based on its nearly complete 16S rRNA gene sequence (1428 nt) with representative strains showed that the strain consistently falls into a distinct phyletic line together with Streptomyces glaucosporus DSM 41689T (98.22 % similarity) and a subclade consisting of Streptomyces atacamensis DSM 42065T (98.40 %), Streptomyces radiopugnans R97 DSM 41901T (98.27 %), Streptomyces fenghuangensis GIMN4.003T (98.33 %), Streptomyces nanhaiensis DSM 41926T (98.13 %), Streptomyces megasporus NBRC 14749T (97.37 %) and Streptomyces macrosporus NBRC 14748T (98.22 %). However, the levels of DNA–DNA relatedness between strain RC 1831T and phylogenetically related strains Streptomyces atacamensis DSM 42065T (28.75±3.25 %) and Streptomyces glaucosporus DSM 41689T (15±2.40 %) were significantly lower than the 70 % threshold value for delineation of genomic species. Furthermore, the isolate could be distinguished phenotypically on the basis of physiological, morphological and biochemical differences from its closest phylogenetic neighbours and other related reference strains. Strain RC 1831T is therefore considered to represent a novel species of the genus Streptomyces , for which the name Streptomyces barkulensis sp. nov. is proposed. The type strain is RC 1831T ( = JCM 18754T = DSM 42082T).

Phospholipid Profile

A Gram-reaction-positive aerobic actinomycete, designated strain MN08-A0118T, which produced short chains of non-motile spores on the tips of long sporophores and formed yellow–brown colonies with branched substrate mycelium, was studied in detail to determine its taxonomic position. On the basis of 16S rRNA gene sequence analyses, strain MN08-A0118T was grouped into the genus Herbidospora , being most closely related to Streptosporangium claviforme (98.2 %), Herbidospora osyris (98.2 %), Herbidospora daliensis (98.2 %), Herbidospora cretacea (97.9 %) and Herbidospora yilanensis (97.4 %). Chemotaxonomic data supported allocation of the strain to the genus Herbidospora . MK-10(H4) was the predominant menaquinone with minor amounts of MK-10(H6), MK-10(H2) and MK-9(H4); the fatty acid profile contained major amounts of iso-C16 : 0, C17 : 0 10-methyl, iso-C14 : 0 and iso-C16 : 0 2-OH; the phospholipid profile contained phosphatidylethanolamine, phosphatidylmethylethanolamine and glucosamine-containing phospholipids; and the whole-cell sugars included ribose, glucose, galactose, madurose and rhamnose (trace). The phylogenetic data, phenotypic and genotypic properties and DNA–DNA hybridization differentiated this strain from its closely related strains, S. claviforme (35–54 % DNA–DNA relatedness), H. osyris (39–51 %), H. daliensis (3–16 %), H. cretacea (34–39 %) and H. yilanensis (34–42 %). Thus, MN08-A0118T represents a novel species of the genus Herbidospora , for which the name Herbidospora mongoliensis sp. nov. is proposed, with MN08-A0118T ( = NBRC 105882T  = VTCC D9-22T) as the type strain. In addition, DNA–DNA hybridization results showed that S. claviforme and H. osyris are synonyms of H. cretacea .

A novel Gram-stain-negative, aerobic, heterotrophic, stalked and capsulated bacterium with potential denitrification ability, designated strain TAR-002T, was isolated from deep seafloor sediment in Japan. Colonies lacked lustre, and were viscous and translucent white. The ranges of temperature, pH and salt concentration for growth were 8–30 °C, pH 6.0–10.0 and 1–3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences confirmed that strain TAR-002T belongs to the genus Brevundimonas of the class Alphaproteobacteria . Levels of similarity between the 16S rRNA gene sequence of strain TAR-002T and those of the type strains of species of the genus Brevundimonas were 93.5–98.9 %; the most closely related species was Brevundimonas basaltis . In DNA–DNA hybridization assays between strain TAR-002T and its phylogenetic neighbours, Brevundimonas lenta DS-18T, B. basaltis J22T, Brevundimonas subvibrioides ATCC 15264T and Brevundimonas alba DSM 4736T, mean hybridization levels were 6.4–27.7 %. The G+C content of strain TAR-002T was 70.3 mol%. Q-10 was the major respiratory isoprenoid quinone. The major fatty acids were C18 : 1ω7c and C16 : 0, and the presence of 1,2-di-O-acyl-3-O-[d-glucopyranosyl-(1→4)-α-d-glucopyranuronosyl]glycerol (DGL) indicates the affiliation of strain TAR-002T with the genus Brevundimonas . On the basis of biological characteristics and 16S rRNA gene sequence comparisons, strain TAR-002T is considered to represent a novel species of the genus Brevundimonas , for which the name Brevundimonas denitrificans sp. nov. is proposed; the type strain is TAR-002T ( = NBRC 110107T = CECT 8537T).

The 16S Rrna Gene

Two strains (J3-AN59T and J3-N84) of Gram-stain-negative, aerobic and rod-shaped bacteria were isolated from the roots of fresh rice plants. The 16S rRNA gene sequence similarity results showed that the similarity between strains J3-AN59T and J3-N84 was 100 %. Both strains were phylogenetically related to members of the genus Rhizobium , and they were most closely related to Rhizobium tarimense ACCC 06128T (97.43 %). Similarities in the sequences of housekeeping genes between strains J3-AN59T and J3-N84 and those of recognized species of the genus Rhizobium were less than 90 %. The polar lipid profiles of both strains were predominantly composed of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and an unknown aminophospholipid. The major cellular fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0. The DNA G+C contents of J3-AN59T and J3-N84 were 55.7 and 57.1 mol%, respectively. The DNA–DNA relatedness value between J3-AN59T and J3-N84 was 89 %, and strain J3-AN59T showed 9 % DNA–DNA relatedness to R. tarimense ACCC 06128T, the most closely related strain. Based on this evidence, we found that J3-AN59T and J3-N84 represent a novel species in the genus Rhizobium and we propose the name Rhizobium rhizoryzae sp. nov. The type strain is J3-AN59T ( = ACCC 05916T = KCTC 23652T).
