A light-pink-coloured bacterium, designated strain 5416T-32T, was isolated from an air sample in Korea. Cells of the strain were strictly aerobic, Gram-negative, motile (single polar or subpolar flagellum) and rod-shaped. Optimal growth occurred at 25–30 °C and at pH 6.0–7.0. The major quinones were Q-10 and Q-8. The major fatty acids were C18 : 1 ω7c (53.8 %) and C16 : 0 (15.9 %). The G+C content of the genomic DNA was 65.0 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 5416T-32T was most closely related to Skermanella parooensis, with a similarity of 96.2 %, but relatively low sequence similarities (<92 %) were found with respect to other species with validly published names held in GenBank. Phenotypic and genotypic analyses indicated that strain 5416T-32T could not be assigned to any recognized species. Therefore strain 5416T-32T represents a novel species of the genus Skermanella, for which the name Skermanella aerolata sp. nov. is proposed. The type strain is 5416T-32T (=KACC 11604T=DSM 18479T).

A sponge-associated strain, KMM 7019T, was investigated in a polyphasic taxonomic study. The bacterium was strictly aerobic, heterotrophic, Gram-negative, yellow-pigmented, motile by gliding and oxidase-, catalase-, β-galactosidase- and alkaline phosphatase-positive. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain KMM 7019T is closely related to members of the genus Salegentibacter, namely Salegentibacter holothuriorum, Salegentibacter mishustinae and Salegentibacter salegens (97·7–98 % sequence similarities). The DNA–DNA relatedness between the strain studied and Salegentibacter species ranged from 27 to 31 %, clearly demonstrating that KMM 7019T belongs to a novel species of the genus Salegentibacter, for which the name Salegentibacter agarivorans sp. nov. is proposed. The type strain is KMM 7019T (=KCTC 12560T=LMG 23205T).

Emended Description

Strain JC268T was isolated from pebbles collected from a dam located in Lalitpur, Uttar Pradesh, India. Cells of strain JC268T were coccoid, appeared in pairs/triads/tetrads or short chains and were Gram-stain-positive, non-spore-forming, non-motile and obligately aerobic. Strain JC268T was catalase- and oxidase-positive and utilized citrate for growth. The genomic DNA G+C content of strain JC268T was 65.3 mol%. The cell-wall peptidoglycan contained l-lysine–l-serine–d-aspartic acid as interpeptide bridge with the type A4α. The major menaquinone was MK-8(H4). Major (>10 %) fatty acids were iso-C16 : 0, iso-C16 : 1H and anteiso-C17 : 1ω9c. Diphosphatidylglycerol, phosphoglycolipid, phosphatidylinositol, glycolipid, four unidentified lipids, an amino lipid and phospholipid were the polar lipids of strain JC268T. EzTaxon-e blast search of 16S rRNA gene sequences showed that strain JC268T has highest similarity to Barrientosiimonas humi 39T (98.65 %) and Tamlicoccus marinus MSW-24T (97.8 %) of the family Dermacoccaceae. Genome reassociation (based on DNA–DNA hybridization) of strain JC268T with Barrientosiimonas humi CGMCC 4.6864T ( = 39T) and T. marinus KCTC 19485T ( = MSW-24T) yielded values of 32.5 ± 2 % and 27.3 ± 2 %, respectively. Based on the data from phylogenetic and polyphasic taxonomic analyses, strain JC268T represents a novel species of the genus Barrientosiimonas for which the name Barrientosiimonas endolithica sp. nov., is proposed. The type strain of Barrientosiimonas endolithica is JC268T ( = KCTC 29672T = NBRC 110608T). Our data suggest that T. marinus should be reclassified within the genus Barrientosiimonas. Thus, a reclassification is proposed for T. marinus, the type and only species of the genus Tamlicoccus, as Barrientosiimonas marina comb. nov., which implies the emendation of the description of the genus Barrientosiimonas.

A halotolerant actinomycete strain, designated XJEEM 11063T, was isolated from a salt lake in Xinjiang province, north-western China. Strain XJEEM 11063T grew at pH 6.0–8.0 (optimal growth at pH 7.0), between 10 and 40 °C (optimal growth at 28–37 °C) and at salinities of 0–10 % (w/v) NaCl (optimal growth at 0–5 %, w/v). The peptidoglycan type was A4α, and the whole-cell hydrolysates contained glucose, mannose and arabinose. The major fatty acids were anteiso-C15 : 0, iso-C15 : 0 and anteiso-C17 : 0. MK-9(H4) was the predominant menaquinone and the polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides, two unknown phospholipids and three unknown glycolipids. The genomic DNA G+C content was 71.8 mol%. The chemotaxonomic properties supported the affiliation of strain XJEEM 11063T to the genus Myceligenerans. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the organism was most closely related to Myceligenerans xiligouense XLG9A10.2T (98.3 %) and Myceligenerans crystallogenes DSM 17134T (97.0 %). However, it had relatively low values for DNA–DNA relatedness with the above strains (56.0 % and 47.5 %, respectively). Thus, on the basis of the results from this study, a novel species, Myceligenerans halotolerans sp. nov., is proposed. The type strain is XJEEM 11063T ( = DSM 21949T = CCTCC AA 208063T).

A novel halophilic archaeon, strain EJ-32T, was isolated from water from Lake Ejinor in Inner Mongolia, China. The taxonomy of strain EJ-32T was studied by using a polyphasic approach. On the basis of 16S rRNA gene sequence similarities, strain EJ-32T was shown to be phylogenetically related to Halorubrum coriense (97.9 %), Halorubrum trapanicum (97.9 %), Halorubrum sodomense (97.8 %), Halorubrum tebenquichense (97.8 %), Halorubrum xinjiangense (97.6 %), Halorubrum terrestre (97.4 %), Halorubrum distributum (97.1 %) and Halorubrum saccharovorum (96.4 %). Strain EJ-32T was found to be neutrophilic, non-motile and Gram-negative. It grew in medium containing saturation concentrations of NaCl and did not require magnesium for optimal growth. The G+C content of the DNA is 64.0 mol%. Values for DNA–DNA hybridization with respect to phylogenetically related Halorubrum species were ≤49 %, indicating that EJ-32T constitutes a different genospecies. The data show that strain EJ-32T represents a novel species of the genus Halorubrum, for which the name Halorubrum ejinorense sp. nov. is proposed. The type strain is EJ-32T (=CECT 7194T=CGMCC 1.6782T=JCM 14265T).
