A Gram-staining-negative, aerobic and rod-shaped bacterium, designated HME8881T, was isolated from a freshwater wetland located in the Republic of Korea. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain HME8881T grouped with members of the genus Ferruginibacter. The most closely related species were Ferruginibacter lapsinanis HU1-HG42T (95.6  %), Ferruginibacter alkalilentus HU1-GD23T (95.1  %), ‘Ferruginibacter profundus’ DS48-5-3 (94.7  %) and Ferruginibacter yonginensis HME8442T (93.4  %). The major fatty acids were iso-C15 : 0, summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), iso-C15 : 1G, C16 : 0 and iso-C17 : 0 3-OH. A polar lipid analysis revealed phosphatidylethanolamine, two unidentified aminolipids, three unidentified aminophospholipids, two unidentified phospholipids and two unidentified lipids. DNA G+C content was 37.7 mol%. These results suggest that strain HME8881T represents a novel species of the genus Ferruginibacter, for which the name Ferruginibacter paludis sp. nov., is proposed with the type strain HME8881T ( = KCTC 42121T = CECT 8366T). In addition, emended descriptions of Ferruginibacter lapsinanis and Ferruginibacter alkalilentus are also proposed on the basis of new data obtained during this study.

Extremely Halophilic Archaeon

An extremely halophilic archaeon belonging to the order Halobacteriales was isolated from Fuente de Piedra salt lake, Spain. This strain, designated FP1T, was a pleomorphic coccoid, neutrophilic and required at least 15 % (w/v) NaCl for growth. Strain FP1T grew at 37–60 °C, with optimal growth at 50 °C. Mg2+ was not required, but growth was observed with up to 10 % (w/v) MgSO4. Polar lipid analysis revealed the presence of mannose-6-sulfate(1-2)-glucose glycerol diether as a major glycolipid. Both C20C20 and C20C25 core lipids were present. The genomic DNA G+C content was 62.0 mol%. Phylogenetic analysis based on comparison of 16S rRNA gene sequences demonstrated that the isolate was most closely related to species of the genus Haloterrigena. DNA–DNA reassociation values between strain FP1T and the most closely related species of the genus Haloterrigena (Haloterrigena thermotolerans, Haloterrigena saccharevitans and Haloterrigena limicola) were lower than 29 %. It is therefore considered that strain FP1T represents a novel species of the genus Haloterrigena, for which the name Haloterrigena hispanica sp. nov. is proposed. The type strain is FP1T (=DSM 18328T=ATCC BAA-1310T).

A Gram-positive, aerobic, non-spore-forming actinobacterial strain, designated strain TL1T, was isolated from pig manure in Wuhan, China. The cell wall peptidoglycan contained meso-diaminopimelic acid. The major polar lipids were phosphatidylethanolamine, phosphatidylinositol and diphosphatidylglycerol. The predominant menaquinone was MK-8(H4). The major fatty acids (>10 %) were iso-C16 : 0, iso-C15 : 0 and C17 : 1ω8c. The genomic DNA G+C content was 70.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain TL1T was most closely related to the type strains of Knoellia sinensis (98.5 %), Knoellia subterranea (98.2 %) and Knoellia aerolata (96.9 %). DNA–DNA relatedness values of strain TL1T with the type strains of K. sinensis and K. subterranea were 27.3 and 34.0 %, respectively. Comparison of phenotypic, chemotaxonomic and phylogenetic characteristics among strain TL1T and related organisms revealed that the isolate represents a novel species of the genus Knoellia, for which the name Knoellia flava sp. nov. is proposed; the type strain is TL1T ( = CGMCC 1.10749T = KCTC 19810T).

Amplified Rdna Restriction Analysis

The taxonomic position of seven soil actinomycetes provisionally assigned to the genus Amycolatopsis was established in a polyphasic study. The isolates, which had identical 16S rRNA gene sequences, had closest similarity to the type strain of Amycolatopsis orientalis. A representative isolate, strain GY080T, had chemotaxonomic properties that were typical of the genus Amycolatopsis and could be distinguished from the type strain of A. orientalis using DNA–DNA relatedness data. All of the isolates shared a phenotypic profile that distinguished them from representatives of phylogenetically closely related species. Amplified rDNA restriction analysis showed that the isolates formed a homogeneous group that was distinctly separate from single-membered groups consisting of representative Amycolatopsis type strains, including that of A. orientalis. Based on the combined genotypic and phenotypic evidence, it is proposed that the seven isolates be classified as representatives of a novel species for which the name Amycolatopsis regifaucium sp. nov. is proposed. The type strain is GY080T (=DSM 45072T =NCIMB 14277T).
