A facultatively chemolithoautotrophic, thiosulfate-oxidizing, Gram-negative, aerobic, motile, rod-shaped bacterial strain, designated ATSB16T, was isolated from rhizosphere soils of sesame (Sesamum indicum L.). 16S rRNA gene sequence analysis demonstrated that this strain was closely related to Pandoraea pnomenusa LMG 18087T (96.7 % similarity), P. pulmonicola LMG 18016T (96.5 %), P. apista LMG 16407T (96.2 %), P. norimbergensis LMG 18379T (96.1 %) and P. sputorum LMG 18819T (96.0 %). Strain ATSB16T shared 96.0–96.4 % sequence similarity with four unnamed genomospecies of Pandoraea. The major cellular fatty acids of the strain ATSB16T were C17 : 0 cyclo (33.0 %) and C16 : 0 (30.6 %). Q-8 was the predominant respiratory quinone. The major polar lipids were phosphatidylmethylethanolamine, diphosphatidylglycerol, phosphatidylethanolamine and two unidentified aminophospholipids. Hydroxyputrescine and putrescine were the predominant polyamines. The genomic DNA G+C content of the strain was 64.0 mol%. On the basis of the results obtained from this study, strain ATSB16T represents a novel species of the genus Pandoraea, for which the name Pandoraea thiooxydans sp. nov. is proposed. The type strain is ATSB16T (=KACC 12757T =LMG 24779T).

A Gram-negative, strictly aerobic, rod-shaped, non-motile, non-spore-forming bacterial strain, designated TR6-04T, was isolated from compost and characterized taxonomically by using a polyphasic approach. The organism grew optimally at 30 °C and at pH 6.5–7.0. The isolate was positive for catalase and oxidase tests but negative for gelatinase, indole and H2S production. Comparative 16S rRNA gene sequence analysis showed that strain TR6-04T fell within the radiation of the cluster comprising Sphingobacterium species and clustered with Sphingobacterium mizutaii ATCC 33299T (96.7 % sequence similarity); the similarity to sequences of other species within the family Sphingobacteriaceae was less than 92.0 %. The G+C content of the genomic DNA was 38.7 mol%. The predominant respiratory quinone was MK-7. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 4 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c). These chemotaxonomic data supported the affiliation of strain TR6-04T to the genus Sphingobacterium. However, on the basis of its phenotypic properties and phylogenetic distinctiveness, strain TR6-04T (=KCTC 12579T=LMG 23402T=CCUG 52468T) should be classified as the type strain of a novel species, for which the name Sphingobacterium daejeonense sp. nov. is proposed.

Strain 7SM29T, an aerobic marine gammaproteobacterium isolated from seawater from Castellón, Spain, was characterized by classical phenotyping, chemotaxonomy and 16S rRNA gene sequence analysis. Strain 7SM29T was found to be closely related to strains in the genus Haliea and to Congregibacter litoralis KT71T, with which a genus-level cluster was formed within the NOR5/OM60 clade of the Gammaproteobacteria. Strain 7SM29T was a short, motile rod with a tuft of three polar flagella. The strain grew on marine agar and formed pale-yellow colonies. Strain 7SM29T required NaCl for growth, reduced nitrate to nitrite, degraded several polymers and showed a preference for organic acids and amino acids over carbohydrates as carbon and energy sources. Strain 7SM29T contained Q-8 as the sole respiratory quinone. The DNA G+C content was 62.1 mol%. Phosphatidylglycerol, diphosphatidylglycerol and phosphatidylethanolamine were the major polar lipids. The major cellular fatty acids were unsaturated C16–C18 compounds. On the basis of extensive phenotypic and phylogenetic comparative analysis, it is concluded that the strain represents a novel species of the genus Haliea, for which the name Haliea mediterranea sp. nov. is proposed.

Two novel Gram-negative, oxidase- and catalase-positive, rod-shaped bacterial strains, designated YCSA28T and YCSA39, were isolated from sediment of Daqiao saltern, Jimo, Qingdao, on the east coast of China. The two strains grew optimally at 28–30 °C, at pH 7.5 and in the presence of 7–8 % (w/v) NaCl. They were assigned to the genus Halomonas, class Gammaproteobacteria, based on 16S rRNA gene sequence analysis. The major cellular fatty acids of the two strains were C18 : 1ω7c (42.9 %), C16 : 0 (23.1 %) and C16 : 1ω7c/ω6c (18.0 %), and Q-9 was the major ubiquinone. The G+C content of the DNA of strains YCSA28T and YCSA39 was 63.7 and 63.9 mol%, respectively. The predominant respiratory lipoquinone, cellular fatty acid profiles and DNA G+C content of strains YCSA28T and YCSA39 were consistent with those of recognized species of the genus Halomonas. Levels of DNA–DNA relatedness between strains YCSA28T and YCSA39, between YCSA28T and Halomonas ventosae Al12T, and between YCSA39 and H. ventosae Al12T were 95, 45 and 50 %, respectively. Together, these data indicated that strains YCSA28T and YCSA39 represent a single novel species of the genus Halomonas, for which the name Halomonas daqiaonensis sp. nov. is proposed. The type strain is YCSA28T ( = CGMCC 1.9150T  = NCCB 100305T  = MCCC 1B00920T).

A Gram-negative, non-motile, aerobic bacterial strain, designated MJ20T, was isolated from farm soil near Daejeon (South Korea) and was characterized taxonomically by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain MJ20T belongs to the family Cytophagaceae, class Sphingobacteria, and was related most closely to Dyadobacter fermentans DSM 18053T (98.9 % sequence similarity), Dyadobacter beijingensis JCM 14200T (98.0 %) and Dyadobacter ginsengisoli KCTC 12589T (96.4 %). The G+C content of the genomic DNA of strain MJ20T was 48.5 mol%. The detection of MK-7 as the predominant menaquinone and a fatty acid profile with summed feature 4 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH), iso-C15 : 0, C16 : 0 and C16 : 1 ω5c as major components supported the affiliation of strain MJ20T to the genus Dyadobacter. The new isolate exhibited relatively low levels of DNA–DNA relatedness with respect to D. fermentans DSM 18053T (mean±sd of three determinations, 47±7 %) and D. beijingensis JCM 14200T (38±8 %). On the basis of its phenotypic and genotypic properties together with phylogenetic distinctiveness, strain MJ20T (=KCTC 22481T =JCM 16232T) should be classified in the genus Dyadobacter as the type strain of a novel species, for which the name Dyadobacter soli sp. nov. is proposed.
