A Gram-negative, rod-shaped, non-spore-forming betaproteobacterium (TRO-001DR8T) was isolated from humic-lake samples collected from northern Wisconsin, USA. On the basis of 16S rRNA gene sequence analysis, strain TRO-001DR8T belonged to the family Neisseriaceae, and the phylogenetic distance from its closest relative, Chromobacterium violaceum, was 95 %. Strain TRO-001DR8T lacked the violet pigmentation of C. violaceum and shared only 26 % DNA–DNA relatedness with C. violaceum. The DNA G+C content of strain TRO-001DR8T was 59 mol%. The predominant fatty acids were C16 : 1 ω7c + C16 : 1 ω7c 2-OH iso (52·5 %), C16 : 0 (21·7 %), C18 : 1 ω7c (8·0 %) and C12 : 0 (5·1 %). Strain TRO-001DR8T grew optimally at 35 °C and pH 6·0, did not utilize sucrose, but did use glucose, some organic acids and most protein amino acids. Biochemical, physiological, chemotaxonomic and phylogenetic analyses showed that strain TRO-001DR8T could not be assigned to any known genus of the Betaproteobacteria. Therefore, the isolate represents a novel genus and species, for which the name Aquitalea magnusonii gen. nov., sp. nov. is proposed. The type strain is TRO-001DR8T (=ATCC BAA-1216T=BCCM/LMG 23054T).

A Gram-reaction-positive, rod-shaped, non-motile, non-spore-forming bacterium (strain BX5-10T) was isolated from the soil of a ginseng field on Baekdu Mountain in Jilin district, China. The taxonomic position of this bacterium was determined in an investigation based on a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain BX5-10T was shown to belong to the family Nocardioidaceae and to be most closely related to Nocardioides plantarum NCIMB 12834T (96.5 % sequence similarity), Nocardioides dokdonensis KCTC 19309T (96.2 %) and Nocardioides fonticola NAA-13T (95.1 %). Strain BX5-10T was characterized chemotaxonomically as having ll-2,6-diaminopimelic acid in its cell-wall peptidoglycan, MK-8(H4) as the predominant menaquinone and C18 : 1ω9c, C16 : 0 and C17 : 1ω8c as its major fatty acids. The G+C content of the genomic DNA was 70.3 mol%. The novel strain could be differentiated genotypically and phenotypically from all recognized species of the genus Nocardioides. Based on the results of the phylogenetic analyses and the genotypic and phenotypic data, a novel species, Nocardioides ginsengagri sp. nov., is proposed. The type strain is BX5-10T ( = KCTC 19467T = DSM 21362T).

Abstract A Gram-negative, non-motile bacterium КММ 3653T was isolated from a sediment sample from the Sea of Japan seashore, Russia. On the basis of the 16S rRNA gene sequence analysis the strain КММ 3653T was positioned within the family Rhodobacteraceae (class Alphaproteobacteria) forming a distinct lineage with the highest gene sequence similarities to the members of the genera Pacificibacter (95.2-94.7%) and Nioella (95.1-94.5%), respectively. According to the phylogenomic tree based on 400 conserved protein sequences, strain КММ 3653T was placed in the cluster comprising Vannielia litorea, Nioella nitratireducens, Litoreibacter albidus and Pseudoruegeria aquimaris as a separate lineage adjacent to Vannielia litorea KCTC 32083T. The average nucleotide identity values between strain КММ 3653T and Vannielia litorea KCTC 32083T, Nioella nitratireducens KCTC 32417T, Litoreibacter albidus KMM 3851T, and Pseudoruegeria aquimaris CECT 7680T were 71.1, 70.3, 69.6, and 71.0%, respectively. Strain КММ 3653T contained Q-10 as the predominant ubiquinone and C18:1ω7c as the major fatty acid followed by C16:0. The polar lipids were phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol, an unidentified phospholipid, two unidentified aminolipids, and five unidentified lipids. The DNA G+C content of 61.8 % was calculated from the genome sequence. Based on the phylogenetic evidence and distinctive phenotypic characteristics, strain КММ 3653T is proposed to be classified as a novel genus and species Laetantesicola maris gen. nov., sp. nov. The type strain of Laetantesicola maris gen. nov., sp. nov. is КММ 3653T (=KCTC 82575T).

Acetogenic Bacterium

Phenotypic and phylogenetic studies were performed on three strains of an acetogenic bacterium isolated from livestock-impacted soil. The bacterium stained Gram-negative and was a non-spore-forming rod that was motile by peritrichous flagella. The novel strains had an optimum pH for growth of 8.0–8.5 and utilized H2 : CO2, CO : CO2, glucose, fructose, mannose, turanose, ribose, trimethylamine, pyruvate, methanol, ethanol, n-propanol and n-butanol as growth substrates. Acetate was produced from glucose. Acetate, CO2 and ethanol were produced from CO : CO2. 16S rRNA gene sequence analysis indicated that the novel strains formed a new subline in the family Eubacteriaceae (rRNA cluster XV) of the low G+C-containing Gram-positive bacteria of the class Clostridia. The DNA G+C base composition was 34 mol%. Cell wall analysis revealed the existence of a novel B-type peptidoglycan similar to the B2α-type (B4) configuration with a variation containing aspartic acid. Based on phylogenetic and phenotypic evidence, it is proposed that the new isolates represent a novel genus and species, for which the name Alkalibaculum bacchi gen. nov., sp. nov. is proposed. The type strain of the type species is CP11T (=ATCC BAA-1772T=DSM 22112T).

A marine bacterium, designated strain KMM 6038T, was subjected to taxonomic analysis via a polyphasic approach. Cells of the strain were heterotrophic, orange-pigmented, Gram-negative and motile by means of gliding. 16S rRNA gene sequence analysis indicated that strain KMM 6038T was closely related to the type species of the genera Algibacter and Yeosuana, members of the family Flavobacteriaceae, with sequence similarities of 93.8 and 93.6 % to the respective type strains. However, several chemotaxonomic and phenotypic characteristics, such as the cellular fatty acid profile (iso-C15 : 0, anteiso-C15 : 0, iso-C15 : 1, C15 : 0, C15 : 1 ω6c, iso-C15 : 0 3-OH and iso-C17 : 0 3-OH) and the low G+C content of the DNA (35.7 mol%), indicated that the strain should be separated from these two genera. From the results of phenotypic, genotypic, chemotaxonomic and phylogenetic analyses, the bacterium should be classified as representing a novel genus and species, for which the name Mariniflexile gromovii gen. nov., sp. nov. is proposed. The type strain of Mariniflexile gromovii is KMM 6038T (=KCTC 12570T=LMG 22578T).

A Gram-stain-negative, aerobic, proteorhodopsin-containing, orange, rod-shaped bacterium, designated SAORIC-234T, was isolated from deep seawater in the Pacific Ocean. 16S rRNA gene sequence analysis revealed that the strain could be affiliated with the family Flavobacteriaceae of the phylum Bacteroidetes and shared less than 94.6 % similarity with other species of the family with validly published names. The phenotypic characteristics of this novel isolate, such as growth properties and enzyme activities, could be differentiated from those of other species. The strain was non-motile, oxidase-positive and catalase-negative. The G+C content of the genomic DNA was determined to be 34.8 mol% and menaquinone-6 (MK-6) was the predominant isoprenoid quinone. The predominant fatty acids were iso-C15 : 0, iso-C15 : 1 G, iso-C16 : 0 3-OH, iso-C17 : 0 3-OH and iso-C15 : 0 3-OH. The major polar lipids comprised phosphatidylethanolamine, three unknown aminolipids and three unknown lipids. On the basis of the taxonomic data collected in this study, it was concluded that strain SAORIC-234T represents a novel genus and species in the family Flavobacteriaceae, for which the name Aurantivirga profunda gen. nov., sp. nov. is proposed. The type strain of the type species, Aurantivirga profunda sp. nov., is SAORIC-234T ( = NBRC 110606T = KACC 18400T).
