Strain VN07A0015T was isolated from soil collected on Cat Ba Island, Vietnam. The taxonomic position of strain VN07A0015T was near Streptomyces aomiensis M24DS4T (98.5 % 16S rRNA gene sequence similarity) and Streptomyces scabrisporus NBRC 100760T (95.6 %), and it clustered within them; however, this cluster was distant from the type strains of other species of the genus Streptomyces . The aerial mycelia of strain VN07A0015T were greyish and formed imperfect spiral spore chains (retinaculiaperti type) with smooth-surfaced spores. The morphological features of strain VN07A0015T were different from those of the type strains of S. aomiensis and S. scabrisporus . The chemotaxonomic characteristics of strain VN07A0015T were typical for all members of the genus Streptomyces , which possessed ll-type diaminopimelic acid, menaquinone MK-9(H6, H8) and the major fatty acids iso-C16 : 0 and iso-C15 : 0. DNA–DNA relatedness between strain VN07A0015T and S. aomiensis NBRC 106164T was less than 30 %. In addition, some physiological and biochemical traits differed from those of S. aomiensis . Therefore, we propose that strain VN07A0015T be classified in the genus Streptomyces as a representative of Streptomyces catbensis sp. nov. (type strain VN07A0015T = VTCC-A-1889T = NBRC 107860T).

A Gram-staining-positive, aerobic, non-motile bacterium, designated strain SJ5-8T, was isolated from seau-jeot (shrimp jeotgal), a traditional fermented seafood in South Korea. Cells were non-spore-forming rods showing catalase- and oxidase-positive reactions. Growth of strain SJ5-8T was observed at 10–37 °C (optimum, 30 °C), at pH 6.0–9.0 (optimum, pH 7.5–8.5) and in the presence of 0–14 % (w/v) NaCl (optimum, 5 %). Phylogenetic inference based on 16S rRNA gene sequences showed that the strain formed a tight phyletic lineage with members of the genus Brevibacterium . Strain SJ5-8T was most closely related to Brevibacterium yomogidense MN-6-aT, Brevibacterium daeguense 2C6-41T and Brevibacterium salitolerans TRM 415T with similarities of 98.9, 97.5 and 97.4 %, respectively. The DNA–DNA relatedness values between strain SJ5-8T and the type strains of B. yomogidense , B. daeguense and B. salitolerans were 51.7±1.9 %, 22.2±4.0 % and 52.4±3.8 %, respectively. Chemotaxonomic data (major sole isoprenoid quinone, MK-8(H2); major diagnostic diamino acid, meso-diaminopimelic acid; major polyamines, putrescine and cadaverine; major cellular fatty acids, anteiso-C15:0, iso-C15:0 and anteiso-C17:0; major polar lipids, phosphatidylglycerol and diphosphatidylglycerol; DNA G+C content, 69.3 mol%) also supported the affiliation of strain SJ5-8T to the genus Brevibacterium . Therefore, strain SJ5-8T represents a novel species of the genus Brevibacterium , for which the name Brevibacterium jeotgali sp. nov. is proposed. The type strain is SJ5-8T ( = KACC 16911T = JCM 18571T).

A psychrotolerant strain, 8H1T, was isolated from soil samples collected in Isla de los Estados, Ushuaia, Argentina. Cells were Gram-negative, aerobic, straight rods, occurring singly or in pairs, non-spore-forming and motile by means of two polar flagella. The isolate was able to grow in the range 4–35 °C, with optimum growth at 28 °C. The predominant cellular fatty acids were summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c), C16 : 0 and summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c). The polar lipid pattern of strain 8H1T comprised phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and an unknown phospholipid. Ubiquinone 9 (Q-9) was the predominant lipoquinone. The DNA G+C content was 59.8 mol%. 16S rRNA gene sequence-based phylogeny suggested the affiliation of strain 8H1T to the ‘Pseudomonas fluorescens group’, displaying ≥98.5 % sequence similarity to 29 type strains. A multilocus sequence analysis (MLSA) study performed by concatenating 16S rRNA, gyrB, rpoD and rpoB gene sequences showed that isolate 8H1T could be discriminated from closely related species of the genus Pseudomonas and placed in the ‘Pseudomonas gessardii subgroup’, including the species with the highest MLSA sequence similarities: Pseudomonas brenneri (96.2 %), P. gessardii (96.1 %), P. proteolytica (96.0 %), P. meridiana (96.0 %) and P. mucidolens (95.4 %). DNA–DNA hybridization analysis between 8H1T and the type strains of these closely related species revealed relatedness values of 27.0, 8.8, 41.2, 39.7 and 46.1 %, respectively. These results, together with differences in several phenotypic features, support the classification of a novel species, for which the name Pseudomonas yamanorum sp. nov. is proposed. The type strain is 8H1T ( = DSM 26522T = CCUG 63249T = LMG 27247T).
