An orange-pigmented, Gram-staining-negative, non-motile, filament-forming, rod-shaped bacterium (BUZ 3T) was isolated from a coastal mud sample from the North Sea (Fedderwardersiel, Germany) and characterized taxonomically using a polyphasic approach. According to 16S rRNA gene sequence data, it belonged to the family Cytophagaceae, exhibiting low 16S rRNA gene sequence similarity (<90 %) with members of the genera Spirosoma, Rudanella and Fibrella. The DNA G+C content was 52.0 mol%. The major fatty acids were summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH), C16 : 1ω5c and iso-C17 : 0 3-OH. The major polar lipids consisted of phosphatidylethanolamine and several aminolipids. On the basis of phenotypic, chemotaxonomic and phylogenetic data, it is proposed that strain BUZ 3T represents a novel genus and species, for which the name Fibrisoma limi gen. nov., sp. nov. is proposed. The type strain is BUZ 3T ( = DSM 22564T  = CCUG 58137T).

Marine Sand

A Gram-staining-negative, motile, agarolytic bacterium, designated M-M1T, was isolated from marine sand obtained from Geoje Island, South Sea, Korea, and its taxonomic position was investigated using a polyphasic taxonomic approach. Strain M-M1T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2 % (w/v) NaCl. It did not grow in the presence of >7 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain M-M1T fell within the clade comprising members of the genus Thalassomonas, clustering with Thalassomonas agarivorans TMA1T, Thalassomonas loyana CBMAI 722T and Thalassomonas ganghwensis JC2041T, with which it exhibited 16S rRNA gene sequence similarity values of 96.4, 96.0 and 94.9 % respectively. Strain M-M1T exhibited 94.7–95.2 % 16S rRNA gene sequence similarity to the other species of the genus Thalassomonas. Strain M-M1T contained Q-8 as the predominant ubiquinone and C16 : 1ω7c and/or iso-C15 : 0 2-OH, C16 : 0 and C18 : 1ω7c as the major fatty acids. The DNA G+C content was 44.2 mol%. Strain M-M1T could be differentiated from phylogenetically related species of the genus Thalassomonas by differences in some phenotypic properties. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain M-M1T is considered to represent a novel species of the genus Thalassomonas, for which the name Thalassomonas agariperforans sp. nov. is proposed. The type strain is M-M1T ( = KCTC 23343T  = CCUG 60020T).

A Gram-stain-negative, aerobic, non-motile, rod-shaped bacterium, designated strain F15T, was isolated from a deep-sea sediment of the western Pacific Ocean. The temperature, pH and NaCl ranges for growth were 4–50 °C, pH 6–11 and 0–10 % (w/v), respectively. Strain F15T showed the highest 16S rRNA gene sequence similarity to Sagittula stellata E-37T (96.4 %), followed by Ponticoccus litoralis CL-GR66T (96.4 %), Antarctobacter heliothermus EL-219T (96.3 %) and Thalassococcus lentus YCS-24T (96.0 %). Phylogenetic analysis based on 16S rRNA gene sequence data showed that strain F15T formed a lineage within the family Rhodobacteraceae of the class Alphaproteobacteria. The polar lipid profile of strain F15T comprised significant amounts of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, one unidentified glycolipid and one unidentified phospholipid. The predominant cellular fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c, 40.2 %), anteiso-C15 : 0 (30.4 %) and anteiso-C17 : 0 (9.7 %). The genomic DNA G+C content of strain F15T was 60.2 mol% and the major respiratory quinone was Q-10. On the basis of phenotypic, phylogenetic and chemotaxonomic data, strain F15T is considered to represent a novel species of a new genus within the family Rhodobacteraceae, for which the name Alkalimicrobium pacificum gen. nov., sp. nov. is proposed. The type strain is F15T ( = LMG 28107T = JCM 19851T = CGMCC 1.12763T = MCCC 1A09948T).

Type Strains

A Gram-staining-negative, aerobic, rod-shaped, non-spore-forming bacterial strain, Ca-34T, was isolated from nodules of chickpea (Cicer arietinum) in Pakistan and studied for its taxonomic affiliation. The almost full-length 16S rRNA gene sequence showed highest similarities to those of strains of the genus Ochrobactrum. Based on results of MALDI-TOF MS and 16S rRNA gene sequence similarity (98.6 %), strain Ca-34T and Ochrobactrum intermedium LMG 3301T are phylogenetic neighbours; the two strains shared DNA–DNA relatedness of 64 %. The fatty acid profile [predominantly C18 : 1 ω7c (67.7 %) and C19 : 0 cyclo ω8c (19.6 %)] also supported the genus affiliation. Metabolically, strain Ca-34T differed from other type strains of Ochrobactrum in many reactions and from all type strains in testing positive for gelatin hydrolysis and in testing negative for assimilation of alaninamide and l-threonine. Based on phenotypic and genotypic data, we conclude that strain Ca-34T represents a novel species, for which we propose the name Ochrobactrum ciceri sp. nov. (type strain Ca-34T =DSM 22292T =CCUG 57879T).

Bletilla Striata

A Gram-stain-positive, non-motile actinomycete, designated strain YIM 48875T, was isolated from rhizosphere soil of Bletilla striata and its taxonomic position was established by using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequence data showed that strain YIM 48875T belonged to the genus Planosporangium, supported by a bootstrap value of 100 %. Cells of strain YIM 48875T showed two kinds of sporangia, which also supported its classification in the genus Planosporangium. Strain YIM 48875T grew optimally at 28 °C, at pH 6.0–8.0 and in the presence of 2 % (w/v) NaCl. The level of 16S rRNA gene sequence similarity between strain YIM 48875T and Planosporangium flavigriseum YIM 46034T was 98.6 %. Strain YIM 48875T exhibited a quinone system with menaquinones MK-9(H4), MK-9(H6) and MK-9(H8) as the predominant compounds, a polar lipid profile comprising diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol mannoside and the major fatty acids iso-C15 : 0 and iso-C16 : 0; these data were markedly different from those for P. flavigriseum YIM 46034T. The level of DNA–DNA relatedness between strain YIM 48875T and P. flavigriseum YIM 46034T was 45.5 %. It is apparent from the genotypic and phenotypic data that strain YIM 48875T represents a novel species of the genus Planosporangium, for which the name Planosporangium mesophilum sp. nov. is proposed. The type strain is YIM 48875T ( = CCTCC AA 209049T  = KCTC 19779T).

Lactobacillus Kefiri

Lactobacillus ferintoshensis has recently been described as a novel species, distinct from its close phylogenetic neighbours Lactobacillus buchneri, Lactobacillus kefiri and Lactobacillus hilgardii. Two highly related species with validly published names, Lactobacillus parakefiri and Lactobacillus parabuchneri, were not considered in the study due to the lack of 16S rRNA gene sequence data at that time. Since the publication of the study, the sequences have become available and have revealed that L. ferintoshensis and L. parabuchneri share 99·7 % 16S rRNA gene sequence similarity. Further genomic and phenotypic data, derived from fluorescent amplified fragment length polymorphism, DNA–DNA hybridization and API 50 CHL analyses, have demonstrated that the species are synonymous.
