Strain Llam7T was isolated from microbial mat samples from the hypersaline lake Salar de Llamará, located in Taracapá region in the hyper-arid core of the Atacama Desert (Chile). Phenotypic, chemotaxonomic and genomic traits were studied. Phylogenetic analyses based on 16S rRNA gene sequences assigned the strain to the family Micromonosporaceae with affiliation to the genera Micromonospora and Salinispora . Major fatty acids were C17 : 1ω8c, iso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0. The cell walls contained meso-diaminopimelic acid and ll-2,6 diaminopimelic acid (ll-DAP), while major whole-cell sugars were glucose, mannose, xylose and ribose. The major menaquinones were MK-9(H4) and MK-9(H6). As polar lipids phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol and several unidentified lipids, i.e. two glycolipids, one aminolipid, three phospholipids, one aminoglycolipid and one phosphoglycolipid, were detected. Genome sequencing revealed a genome size of 6.894 Mb and a DNA G+C content of 71.4 mol%. Phylogenetic analyses with complete genome sequences positioned strain Llam7T within the family Micromonosporaceae forming a distinct cluster with Micromonospora (former Xiangella ) phaseoli DSM 45730T. This cluster is related to Micromonospora pelagivivens KJ-029T, Micromonospora craterilacus NA12T, and Micromonospora craniellae LHW63014T as well as to all members of the former genera Verrucosispora and Jishengella , which were re-classified as members of the genus Micromonospora , forming a clade distinct from the genus Salinispora . Pairwise whole genome average nucleotide identity (ANI) values, digital DNA–DNA hybridization (dDDH) values, the presence of the diamino acid ll-DAP, and the composition of whole sugars and polar lipids indicate that Llam7T represents a novel species, for which the name Micromonospora tarapacensis sp. nov. is proposed, with Llam7T (=DSM 109510T,=LMG 31023T) as the type strain.

Eight facultatively anaerobic rod-shaped bacteria were isolated from raw milk and two other dairy products. Results of phylogenetic analyses based on 16S rRNA gene sequences showed that the isolates are placed in a distinct lineage within the family Propionibacteriaceae with Propioniciclava sinopodophylli and Propioniciclava tarda as the closest relatives (94.6 and 93.5 % similarity, respectively). The cell-wall peptidoglycan contained meso-diaminopimelic acid, alanine and glutamic acid and was of the A1γ type (meso-DAP-direct). The major cellular fatty acid was anteiso-C15 : 0 and the major polar lipids were diphosphatidylglycerol, phosphatidyglycerol and three unidentified glycolipids. The quinone system contained predominantly menaquinone MK-9(H4). The G+C content of the genomic DNA of strain VG341T was 67.7 mol%. The whole-cell sugar pattern contained ribose, rhamnose, arabinose and galactose. On the basis of phenotypic and genetic data, eight strains (VG341T, WS4684, WS4769, WS 4882, WS4883, WS4901, WS4902 and WS4904) are proposed to be classified as members of a novel species in a new genus of the family Propionibacteriaceae , for which the name Brevilactibacter flavus gen. nov., sp. nov. is proposed. The type strain is VG341T (=WS4900T=DSM 100885T=LMG 29089T) and seven additional strains are WS4684, WS4769, WS4882, WS4883, WS4901, WS4902 and WS4904. Furthermore, we propose the reclassification of P. sinopodophylli as Brevilactibacter sinopodophylli comb. nov.

Two Gram-stain-negative, facultatively anaerobic and endospore-forming rod-shaped bacterial strains, THMBG22T and R24, were isolated from decomposing algal scum. Phylogenetic analysis of 16S rRNA gene sequences showed that the two strains were closely related to each other (99.7 % similarity) and that they were also closely related to Paenibacillus sacheonensis DSM 23054T (97–97.1 %) and Paenibacillus phyllosphaerae DSM 17399T (96.1–96.4 %). This affiliation was also supported by rpoB-based phylogenetic analyses. Growth was observed at 20–40 °C (optimum, 30–37 °C) and at pH 5.0–9.0 (optimum, pH 6.0–7.0). The cells contained MK-7 as the sole respiratory quinone and anteiso-C15 : 0 as the major cellular fatty acid. Their cellular polar lipids were composed of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and 12 unidentified polar lipids. The diamino acid of their cell-wall peptidoglycan was meso-diaminopimelic acid. The DNA–DNA hybridization value between THMBG22T and R24 was 84 %, and DNA–DNA relatedness to the most closely related species with a validly published name ( P. sacheonensis ) was 35–37 %. These results supported the assignment of the new isolates to the genus Paenibacillus and also distinguished them from the previously described species of the genus Paenibacillus . Hence, it is proposed that strains THMBG22T and R24 represent a novel species of the genus Paenibacillus , with the name Paenibacillus taihuensis sp. nov. The type strain is THMBG22T ( = CGMCC 1.10966T = NBRC 108766T).

A Gram-negative, rod-shaped, aerobic bacterial strain, designated EBTL01T, was isolated from activated sludge by using metabolites of microalgae Ankistrodesmus gracilis SAG278-2. Phylogenetic analyses based on 16S rRNA gene sequence showed that strain EBTL01T belongs to the family Verrucomicrobiaceae , class Verrucomicrobiae , and is related most closely to Luteolibacter pohnpeiensis A4T-83T (95.5 % sequence similarity) and Luteolibacter algae A5J-41-2T (95.2 %). The G+C content of the genomic DNA of strain EBTL01T was 56.3 mol% and the menaquinone MK-9 was detected as the predominant quinone. Major fatty acid components were iso-C14 : 0, C16 : 1ω7c and C16 : 0. The amino acids of the cell-wall peptidoglycan contained muramic acid and meso-diaminopimelic acid. These profile results supported the affiliation of strain EBTL01T to the genus Luteolibacter . On the other hand, based on chemotaxonomic properties and phenotypic characteristics, strain EBTL01T could be clearly differentiated from its phylogenetic neighbours. Therefore, strain EBTL01T represents a novel species of the genus Luteolibacter , for which the name Luteolibacter yonseiensis sp. nov. is proposed. The type strain is EBTL01T ( = KCTC 23678T = JCM 18052T).

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).
