A Gram-positive, coccobacillus, white raised and circular with an entire edge colony, and obligately anaerobic bacterium, strain SW178 was isolated from the cecum content of feral chickens in Brookings, South Dakota, USA. The most closely related strain based on 16S rRNA gene sequence analysis of strain SW178 was Mediterraneibacter torques ATCC 27756T (Ruminococcus torques ATCC 27756T) with 96.94% similarity. The genome of strain SW178 is 3.18 Mbp with G+C content of 46.9 mol%. The optimal temperature and pH for growth in modified brain heart infusion (BHI-M) medium were 45 °C and pH 7.5, respectively. The sole carbon sources of the strain were dextrin, L-fucose, D-galacturonic, α-D-glucose, L-rhamnose and D-sorbitol. The primary cellular fatty acids were C14 : 0, C16 : 0 and C16 : 0 dimethyl acetal (DMA). Based on the genotypic and phenotypic comparison, we proposed that strain SW178 belong to the genus Mediterraneibacter in the family Lachnospiraceae as a novel species, in which the name Mediterraneibacter catenae is proposed. The type strain is SW178 (= DSM 109242T = CCOS 1886T).

Curved Rods

An arsenite-oxidizing bacterium, designated strain ULPAs1T, was isolated from industrial sludge heavily contaminated with arsenic. Cells of this isolate were Gram-negative, curved rods, motile by means of a polar flagellum. The strain was positive for oxidase and catalase activities, was able to reduce nitrate to nitrite, used acetate, lactate and peptone as organic carbon sources under aerobic conditions and was able to oxidize arsenite (As[III]) to arsenate (As[V]). 16S rRNA gene sequence analysis and the absence of dodecanoic fatty acids suggested that this strain represents a member of the genus Herminiimonas of the family Oxalobacteraceae, order Burkholderiales in the Betaproteobacteria. Genomic DNA–DNA hybridization between strain ULPAs1T and Herminiimonas fonticola S-94T and between strain ULPAs1T and Herminiimonas aquatilis CCUG 36956T revealed levels of relatedness of <10 %, well below the recommended 70 % species cut-off value. Thus, strain ULPAs1T (=CCM 7303T=DSM 17148T=LMG 22961T) is the type strain of a novel species of Herminiimonas, for which the name Herminiimonas arsenicoxydans sp. nov. is proposed.

A Gram-stain-negative, rod-shaped, non-spore-forming bacterium (strain JM-1396T) producing a yellow pigment, was isolated from the healthy internal stem tissue of post-harvest cotton (Gossypium hirsutum, cultivar ‘DES-119’) grown at the Plant Breeding Unit at the E. V. Smith Research Center in Tallassee (Macon county), AL, USA. 16S rRNA gene sequence analysis of strain JM-1396T showed high sequence similarity values to the type strains of Novosphingobium mathurense, Novosphingobium panipatense (both 98.6 %) and Novosphingobium barchaimii (98.5 %); sequence similarities to all other type strains of species of the genus Novosphingobium were below 98.3 %. DNA–DNA pairing experiments of the DNA of strain JM-1396T and N. mathurense SM117T, N. panipatense SM16T and N. barchaimii DSM 25411T showed low relatedness values of 8 % (reciprocal 7 %), 24 % (reciprocal 26 %) and 19 % (reciprocal 25 %), respectively. Ubiquinone Q-10 was detected as the dominant quinone; the fatty acids C18 : 1ω7c (71.0 %) and the typical 2-hydroxy fatty acid, C14 : 0 2-OH (11.7 %), were detected as typical components. The polar lipid profile contained the diagnostic lipids diphosphatidylglycerol, phosphatidylethanolamine, sphingoglycolipid and phosphatidylcholine. The polyamine pattern contained the major compound spermidine and only minor amounts of other polyamines. All these data revealed that strain JM-1396T represents a novel species of the genus Novosphingobium. For this reason we propose the name Novosphingobium gossypii sp. nov. with the type strain JM-1396T ( = LMG 28605T = CCM 8569T = CIP 110884T).

Strain 92VT required seawater for growth with optimal growth occurring at 25 °C, at pH 6–7 and with 3 % (w/v) NaCl. MK-6 was the sole respiratory quinone present and the major fatty acids were iso-C17 : 0 3-OH, iso-C15 : 0, iso-C17 : 1ω9c and iso-C15 : 0 3-OH. The DNA G+C content was 36.1 mol%. Combined phenotypic differences and phylogenetic analysis indicate that strain 92VT represents a novel species of the genus Aquimarina , for which the name Aquimarina amphilecti sp. nov. is proposed. The type strain is 92VT ( = NCIMB 14723T = DSM 25232T).

A bacterial strain, DC-186T, isolated from home-made compost, was characterized for its phenotypic and phylogenetic properties. The isolate was a Gram-negative rod that was able to grow at 15–36 °C and pH 5.5–8.0. Strain DC-186T was positive in tests for catalase, oxidase and β-galactosidase activities and aesculin hydrolysis. The predominant fatty acids were the summed feature C16 : 1/iso-C15 : 0 2-OH (42 %) and iso-C15 : 0 (26 %), the major respiratory quinone was menaquinone-7 and the genomic DNA G+C content was 42 mol%. 16S rRNA gene sequence analysis and phenetic characterization indicated that this organism belongs to the phylum Bacteroidetes and revealed its affiliation to the family Sphingobacteriaceae. Of recognized taxa, strain DC-186T was most closely related to Sphingobacterium daejeonense (90 % sequence similarity) based on 16S rRNA gene sequence analysis. The low 16S rRNA gene sequence similarity with other recognized taxa and the identification of distinctive phenetic features for this isolate support the definition of a new genus within the family Sphingobacteriaceae. The name Pseudosphingobacterium domesticum gen. nov., sp. nov. is proposed, with strain DC-186T (=CCUG 54353T=LMG 23837T) as the type strain.
