Two Gram-positive, catalase-positive, irregular short rod- or coccoid-shaped bacterial strains, N113T and R33, were isolated from an enrichment culture with diesel oil-degradation activity and their taxonomic positions were investigated using a polyphasic approach. Phenotypic, phylogenetic and genetic similarities indicated that strains N113T and R33 were representatives of the same species. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains N113T and R33 form a lineage independent from those of members of the family Intrasporangiaceae. The novel isolates had cell-wall peptidoglycan based on meso-diaminopimelic acid, MK-8(H4) as the predominant menaquinone and 10-methyl-C18 : 0, iso-C16 : 0, C18 : 1 ω9c, C16 : 0 and C18 : 0 as the major cellular fatty acids. The DNA G+C contents were 69.6–69.9 mol%. These chemotaxonomic properties, together with phylogenetic distinctiveness, distinguish the two novel strains from recognized members of the family Intrasporangiaceae. On the basis of phenotypic, phylogenetic and genetic data, strains N113T (=KCTC 19143T=JCM 13585T) and R33 are classified as representatives of a novel genus and species, Kribbia dieselivorans gen. nov., sp. nov., within the family Intrasporangiaceae.

Four Gram-positive, catalase-positive, short rod- or coccoid-shaped bacterial strains, R27T, R44, R45 and R47, were isolated from an enrichment culture with diesel oil-degradation activity and their taxonomic positions were investigated using a polyphasic approach. Phenotypic, phylogenetic and genetic similarities indicated that strains R27T, R44, R45 and R47 belong to the same species. Phylogenetic analysis based on 16S rRNA gene sequences showed that the four strains form a distinct evolutionary lineage within the family Propionibacteriaceae. The novel four strains had cell-wall peptidoglycan based on ll-diaminopimelic acid, MK-9(H4) as the predominant menaquinone and anteiso-C15 : 0 as the major cellular fatty acid. The DNA G+C contents were 68.8–69.2 mol%. These chemotaxonomic properties, together with phylogenetic distinctiveness, distinguish the four novel strains from recognized members of the family Propionibacteriaceae. On the basis of phenotypic, chemotaxonomic, phylogenetic and genetic data, strains R27T, R44, R45 and R47 are classified as representatives of a new genus and novel species, Aestuariimicrobium kwangyangense gen. nov., sp. nov., within the family Propionibacteriaceae. The type strain of Aestuariimicrobium kwangyangense sp. nov. is R27T (=KCTC 19182T=JCM 14204T).

Three bacterial strains, designated CCUG 51397T, CCUG 53736 and CCUG 53920, isolated from water samples taken at different locations in southern Sweden were studied to determine their taxonomic position using a polyphasic approach. Comparative analysis of 16S rRNA gene sequences showed that these bacteria had <93 % sequence similarity to all described species of the genera Sediminibacterium, Lacibacter, Flavihumibacter, Flavisolibacter, Niabella, Niastella, Segetibacter, Parasegetibacter, Terrimonas, Ferruginibacter, Filimonas and Chitinophaga. The three organisms grouped most closely with Sediminibacterium salmoneum NJ-44T but showed only 92.5 % sequence similarity to this strain, the only recognized species of this genus. The fatty acid profiles showed large amounts of iso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 1 G with smaller amounts of iso-C15 : 0 3-OH, iso-C16 : 0 3-OH and other fatty acids, which differentiated the novel strains from related genera. Biochemical tests performed on strains CCUG 51397T, CCUG 53736 and CCUG 53920 also gave different results from those of Sediminibacterium salmoneum NJ-44T and other related genera. Based on this evidence, strains CCUG 51397T, CCUG 53736 and CCUG 53920 represent a novel species of a new genus, for which the name Hydrotalea flava gen. nov., sp. nov. is proposed. The type strain of Hydrotalea flava is CCUG 51397T (=CCM 7760T). A formal allocation of the genera Sediminibacterium, Lacibacter, Flavihumibacter, Flavisolibacter, Niabella, Niastella, Segetibacter, Parasegetibacter, Terrimonas, Ferruginibacter, Filimonas and Chitinophaga to the family Chitinophagaceae fam. nov. is also proposed.

Taxonomic Approach

The taxonomic position of three bacterial strains, Asr22-19T, NBRC 101035 and NBRC 101041, isolated from shellfish in Japan, was determined by using a polyphasic taxonomic approach. The strains were facultatively anaerobic, motile by gliding and Gram-staining-negative slender rods. Their major respiratory quinone was menaquinone-7 and their predominant cellular fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 0 3-OH, C16 : 0 3-OH, and C16 : 0. The G+C content of the genomic DNA was 42.0–42.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strains clustered with the genus Persicobacter in the family ‘Flammeovirgaceae’. DNA–DNA relatedness values were higher than 68 % among strains Asr22-19T, NBRC 101035 and NBRC 101041, and were lower than 28 % between strain Asr22-19T and Persicobacter diffluens NBRC 15940T. The three novel strains could be differentiated from Persicobacter diffluens by several phenotypic characteristics. On the basis of these results, the novel species Persicobacter psychrovividus sp. nov. (type strain Asr22-19T=NBRC 101262T=CIP 109100T) is proposed and emended descriptions are given for the genus Persicobacter and for Persicobacter diffluens.

Sequence Similarities

A mesophilic strain, designated A 9500T, was isolated from a soil sample collected from Sobaek Mountain, South Korea, and its taxonomic position was investigated by using a polyphasic approach. The novel strain grew well on different ISP media and no diffusible pigments were produced. The optimum temperature for growth was 32 °C. The aerial mycelium was well developed, but not fragmented. The strain was Gram-positive, non-motile and formed endospores on vegetative and aerial hyphae with a spiny surface. Cell walls of strain A 9500T contained meso-diaminopimelic acid as the diagnostic amino acid, but no characteristic sugars or other amino acids were found (chemotype-III). The major menaquinone was MK-9(H4) and the minor menaquinone was MK-10(H4) and they were detected at a ratio of 7 : 3. Phosphatidylethanolamine was the diagnostic phospholipid. The G+C content of the genomic DNA was 39.4 mol%. The major fatty acids were anteiso-C15 : 0 (43.34 %), iso-C16 : 0 (14.23 %) and C16 : 0 (7.90 %), a composition that differed from members of related genera of the family Thermoactinomycetaceae. The novel strain formed a distinct clade in a phylogenetic tree based on 16S rRNA gene sequences. On the basis of a range of phenotypic and genotypic data and on 16S rRNA gene sequence similarities (88.35–90.38 %), it is suggested that strain A 9500T represents a novel species in a new genus with the name Shimazuella kribbensis gen. nov., sp. nov. The type strain of the type species is A 9500T (=KCTC 9933T=DSM 45090T).

Two non-motile, orange- or yellow-pigmented bacteria, designated strains KYW48T and KYW147T, were isolated from seawater collected from the South Sea, Republic of Korea. Cells of both strains were Gram-reaction-negative, aerobic and catalase- and oxidase-positive. The major fatty acids of strain KYW48T were C18 : 1ω7c (35.3 %), summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c) (22.7 %), C17 : 1ω6c (19.8 %), C14 : 0 2-OH (7.4 %) and C16 : 0 (5.9 %), and those of strain KYW147T were C18 : 1ω7c (36.0 %), summed feature 3 (18.3 %), C16 : 0 (14.7 %), 11-methyl C18 : 1ω7c (10.7 %), C16 : 0 2-OH (9.1 %) and C18 : 1ω9c (8.0 %). The predominant isoprenoid quinone of both strains was ubiquinone 10 (Q-10). The DNA G+C contents of strains KYW48T and KYW147T were 63.8 and 67.2 mol%, respectively. A phylogenetic tree based on 16S rRNA gene sequences showed that strains KYW48T and KYW147T were grouped with the members of the family Erythrobacteraceae and formed a distinct clade with the members of the genus Altererythrobacter (<95.7 % sequence similarity). On the basis of the evidence presented in this study, the novel species Altererythrobacter namhicola sp. nov. (type strain KYW48T  = KCTC 22736T  = JCM 16345T) and Altererythrobacter aestuarii sp. nov. (type strain KYW147T  = KCTC 22735T  = JCM 16339T) are proposed.

A Gram-positive, rod-shaped, non-spore-forming and strictly aerobic bacterium (Gsoil 161T) was isolated from soil of a ginseng field in Pocheon Province, South Korea. The novel isolate was characterized using a polyphasic approach in order to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarity, strain Gsoil 161T was shown to belong to the family Nocardioidaceae and was related to Aeromicrobium marinum (98.0 % similarity to the type strain), Aeromicrobium alkaliterrae (97.6 %), Aeromicrobium fastidiosum (97.0 %) and Aeromicrobium erythreum (96.7 %); the sequence similarity with other species within the family was less than 94.4 %. It was characterized chemotaxonomically as having ll-2,6-diaminopimelic acid in the cell-wall peptidoglycan, MK-9(H4) as the predominant menaquinone and C16 : 0, 10-methyl C18 : 0 (tuberculostearic acid), C16 : 0 2-OH, 10-methyl C17 : 0 and 10-methyl-C16 : 0 as the major fatty acids. The G+C content of the genomic DNA was 65.5 mol%. These chemotaxonomic properties and phenotypic characteristics support the affiliation of strain Gsoil 161T to the genus Aeromicrobium. Results of physiological and biochemical tests enabled strain Gsoil 161T to be differentiated genotypically and phenotypically from currently known Aeromicrobium species. Therefore, strain Gsoil 161T represents a novel species, for which the name Aeromicrobium panaciterrae sp. nov. is proposed. The type strain is strain Gsoil 161T (=KCTC 19131T=DSM 17939T=CCUG 52476T).
