A novel Gram-negative strain, designated M-SX103T, was isolated from a fresh leaf of Nicotiana tabacum Linn. collected at Yuxi City, Yunnan province, China, and subjected to a polyphasic taxonomic study. Growth occurred at 10–40 °C, at pH 6.0–9.0 and with 0–3 % (w/v) NaCl. The predominant isoprenoid quinone was MK-7. The major cellular fatty acids of strain M-SX103T were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The G+C content of the genomic DNA was 40.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate belongs to the genus Sphingobacterium , sharing 95.4–89.7 % sequence similarity with type strains of members of the genus Sphingobacterium ; it was most closely related to Sphingobacterium composti T5-12T. On the basis of the taxonomic evidence, a novel species, Sphingobacterium nematocida sp. nov., is proposed. The type strain is M-SX103T ( = JCM 17339T = CCTCC AB 2010390T).

An orange, rod-shaped, Gram-reaction-negative, aerobic and gliding bacterial strain devoid of flagella, designated strain KYW614T, was isolated from seawater collected from Gwangyang Bay, Republic of Korea. Zeaxanthin was the major carotenoid pigment produced and flexirubin-type pigments were not produced. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain KYW614T belonged to the family Flavobacteriaceae and it was most closely related to Mesoflavibacter zeaxanthinifaciens TD-ZX30T (96.5 %, sequence similarity). The predominant cellular fatty acids of strain KYW614T were iso-C15 : 1 G (10.5 %), summed feature 3 (C16 : 1ω7c/C16 : 1ω6c; 10.0 %), iso-C15 : 0 (9.5 %), C15 : 0 (7.5 %) and iso-C17 : 0 3-OH (7.4 %). MK-6 was the only isoprenoid quinone and the DNA G+C content was 32.6 mol%. Data from a polyphasic taxonomic study suggested that the isolate represents a novel species in the genus Mesoflavibacter , for which the name Mesoflavibacter aestuarii sp. nov. is proposed. The type strain is KYW614T ( = KCTC 32269T = JCM 19524T).

A novel actinobacterial strain, A4029T, isolated from arid soil of Abuja, Nigeria, and provisionally assigned to the genus Actinoplanes , was subjected to a polyphasic taxonomic study. 16S rRNA gene sequence similarity studies showed that strain A4029T belonged to the genus Actinoplanes , being most closely related to Actinoplanes brasiliensis DSM 43805T (98.9 %) and Actinoplanes deccanensis DSM 43806T (98.0 %); similarity to other type strains of the genus Actinoplanes ranged from 96.2 to 97.9 %. Chemotaxonomic data [major menaquinone MK-9(H4); major polar lipids phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol; characteristic sugars arabinose and xylose; major fatty acids iso-C15 : 0, anteiso-C15 : 0, iso-C16 : 0, C17 : 1ω9c and iso-C14 : 0] confirmed the affiliation of strain A4029T to the genus Actinoplanes . The results of DNA–DNA hybridizations and phylogenetic analysis, together with phenotypic and biochemical test data, allowed strain A4029T to be differentiated from strains of other Actinoplanes species. Therefore, strain A4029T represents a novel species, for which the name Actinoplanes abujensis sp. nov. is proposed, with A4029T ( = DSM 45518T = NRRL B-24835T = KCTC 19984T) as the type strain.

A Gram-stain-negative, aerobic, orange-pigmented, rod-shaped and non-motile bacterium, designated strain A6B8T, was isolated from seawater of the Mariana Trench. The isolate grew at 4–50 °C (optimum 30–35 °C), at pH 6.5–8.0 (optimum pH 7.5) and with 0.5–4.0 % (w/v) NaCl (optimum 1.0–2.0 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain A6B8T was related most closely to the genus Muriicola and shared highest sequence similarity of 97.7 % with Muriicola jejuensis EM44T. Chemotaxonomic analysis showed menaquinone 6 (MK-6) was the predominant isoprenoid and iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH were the major cellular fatty acids. The polar lipid profile of strain A6B8T included phosphatidylethanolamine, three unidentified aminolipids and four unidentified lipids. The genomic DNA G+C content was 47.1 mol%. The DNA–DNA relatedness value (23.3 %) clearly demonstrated that strains A6B8T and M. jejuensis EM44T were representatives of two different species. Based on the phenotypic, phylogenetic and chemotaxonomic characterizations, A6B8T ( = CGMCC 1.12606T = KCTC 32436T) is considered to be the type strain of a novel species of the genus Muriicola , for which the name Muriicola marianensis sp. nov. is proposed.
