Nonomuraea soli sp. nov., an actinomycete isolated from soil.

ABSTRACT: A straight-chain, spore-forming actinobacterium, strain YIM 120770(T), was isolated from soil. Phylogenetic analysis on the basis of 16S rRNA gene sequence comparisons revealed that the isolate represents a distinct cluster within the clade comprising the genus Nonomuraea and is related most closely to Nonomuraea rhizophila YIM 67092(T) (96.5% similarity). Cells of strain YIM 120770(T) grew in the presence of 0-3% (w/v) NaCl, at 15-37 °C and at pH 7.0-8.0. The diagnostic amino acid was meso-diaminopimelic acid, cell hydrolysates contained madurose, glucose, mannose, ribose and galactose, the predominant cellular fatty acids were 10-methyl C(17:0) and iso-C(16:0), and the DNA G+C content was 66.4 mol%, data consistent with affiliation of strain YIM 120770(T) to the genus Nonomuraea. Strain YIM 120770(T) shared low levels of 16S rRNA gene sequence similarity (<97%) with the type strains of recognized species of the genus Nonomuraea and could be differentiated from its closest phylogenetic relative based on phenotypic characteristics. These results suggested that strain YIM 120770(T) represents a novel species of the genus Nonomuraea, for which the name Nonomuraea soli sp. nov. is proposed. The type strain is YIM 120770(T) (=DSM 45533(T)=JCM 17347(T)).

Project description:Four novel strains were isolated: PWU4T and PWU20T were both from soil in Germany, PWU5T was isolated from soil in India and PWU37T was obtained from sheep faeces collected on the Island of Crete. Cells of each were observed to be Gram-negative, strictly aerobic, rod shaped, and to grow optimally between 28 and 34 °C, between pH 7.0 and 8.0 and without the addition of NaCl. The strains were found to be catalase and oxidase-negative and able to grow on most mono- and disaccharides, a few polysaccharides and organic acids. Their predominant menaquinone was identified as MK-7. Their major fatty acids were identified as C16:1 ω7c (PWU4T and PWU20T) and C16:1 ω5c (PWU5T and PWU37T). The DNA G + C contents of strains PWU4T, PWU20T, PWU5T and PWU37T were determined to be 50.2 mol%, 51.6 mol %, 39.8 mol% and 53.8 mol%, respectively. The 16S rRNA gene sequence analysis revealed that the close relatives Ohtaekwangia koreensis 3B-2T and Ohtaekwangia kribbensis 10AOT share less than 93.8% sequence similarity. The strains were classified in two groups, where PWU4T and PWU20T share 93.0% sequence similarity, and PWU5T and PWU37T share 97.5% sequence similarity. However, the members of each group were concluded to represent different species based on the low average nucleotide identity (ANI) of their genomes, 69.7% and 83.8%, respectively. We propose that the four strains represent four novel species of two new genera in the family Cytophagaceae. The type species of the novel genus Chryseosolibacter is Chryseosolibacter histidini gen. nov., sp. nov. with the type strain PWU4T (= DSM 111594T = NCCB 100798T), whilst strain PWU20T (= DSM 111597T = NCCB 100800T) is the type strain of a second species, Chryseosolibacter indicus sp. nov. The type species of the novel genus Dawidia is Dawidia cretensis gen. nov., sp. nov. with the type strain PWU5T (= DSM 111596T = NCCB 100799T), whilst strain PWU37T (= DSM 111595T = NCCB 100801T) is the type stain of a second species, Dawidia soli sp. nov.
