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.

A Gram-stain-positive, aerobic, non-motile, psychrophilic bacterium, designated strain Cr6-08T, was isolated from alpine glacier cryoconite. Growth of strain Cr6-08T occurred at 1–25 °C. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain Cr6-08T is most closely related to members of the genus Arthrobacter. Strain Cr6-08T possessed chemotaxonomic properties consistent with those of the genus Arthrobacter, such as peptidoglycan type A3α (l-Lys–l-Ala4), MK-9(H2) as major menaquinone and anteiso- and iso-branched compounds (anteiso-C15 : 0 and iso-C15 : 0) as major cellular fatty acids. The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, one unknown glycolipid and three unknown polar lipids. The genomic DNA G+C content of strain Cr6-08T was 57.3 mol%. On the basis of phenotypic and chemotaxonomic characteristics, phylogenetic analysis and DNA–DNA relatedness data, strain Cr6-08T is considered to represent a novel species of the genus Arthrobacter, for which the name Arthrobacter cryoconiti sp. nov. is proposed.

Two Gram-stain-positive, aerobic, rod-shaped, pink and light pink colony-forming bacteria, designated as Hz2T and MDT2-14T, respectively, were isolated from glacier cryoconite samples. Comparisons based on 16S rRNA gene sequences showed that strains Hz2T and MDT2-14T take Arthrobacter bussei KR32T and Arthrobacter zhaoguopingii J391T as their closest neighbours, respectively. The average nucleotide identity values between the two novel strains and their closest relatives were 83.56 and 93.06 %, respectively. The two strains contain MK-9(H2) as their predominant menaquinone. The polar lipids of both strains were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol and an unidentified glycolipid. The major fatty acids of strain Hz2T were anteiso-C15 : 0, summed feature 3 (comprising C16 : 1  ω7c and/or C16 : 1  ω6c) and iso-C15 : 0, while the major fatty acids of strain MDT2-14T were anteiso-C15 : 0 and anteiso-C17 : 0. Based on these data, we propose two novel species, Arthrobacter cheniae sp. nov. (Hz2T = CGMCC 1.9262T=NBRC 113086T) and Arthrobacter frigidicola sp. nov. (MDT2-14T=CGMCC 1.9882T=NBRC 113089T).

A Gram-stain-negative, non-motile and aerobic bacterium, designated CF17T, was isolated from coastal planktonic seaweeds, East China Sea. The isolate grew at 18–37 °C (optimum 25–28 °C), pH 6.5–9.0 (optimum 7.0–8.0) and with 0–5 % NaCl (optimum 1–2 %, w/v) and 0.5–10 % sea salts (optimum 2–3 %, w/v). Growth of strain CF17T could be stimulated prominently by supplementing the growth medium with the autoclaved supernatant of a culture of strain CF5, which was isolated from the same sample along with strain CF17T. The cell morphology of strain CF17T was a bean-shaped rod consisting of a swollen end and a long prostheca. The phylogenetic analysis of 16S rRNA gene sequences indicated that strain CF17T clustered with Gemmobacter nectariphilus DSM 15620T within the genus Gemmobacter . The DNA G+C content of strain CF17T was 61.4 mol%. The respiratory quinone was ubiquinone Q-10. The major fatty acids included C18 : 1ω7c and C18 : 0. The polar lipids of strain CF17T consisted of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, two uncharacterized phospholipids, one uncharacterized aminolipid, three uncharacterized glycolipids and one uncharacterized lipid. On the basis of phenotypic, phylogenetic and chemotaxonomic data, strain CF17T ( = CGMCC 1.11024T = JCM 18498T) is considered to represent a novel species of the genus Gemmobacter , for which the name Gemmobacter megaterium sp. nov. is proposed.
