Taxonomic Approach

The taxonomic status of an actinobacterial strain isolated from Mariana Trench sediment was determined using a polyphasic taxonomic approach. The strain, isolate MT1.1T, formed a distinct clade in the Micrococcineae 16S rRNA gene tree together with Dermacoccus nishinomiyaensis DSM 20448T. The organism had chemical and phenotypic properties consistent with its classification in the genus Dermacoccus and could be distinguished from D. nishinomiyaensis DSM 20448T using DNA–DNA relatedness and phenotypic data. The G+C content of the DNA of isolate MT1.1T was 65.2 mol%. It is evident that the organism merits recognition as a novel species in the genus Dermacoccus. The name proposed for this taxon is Dermacoccus abyssi sp. nov.; the type strain is MT1.1T (=DSM 17573T=NCIMB 14084T). The organism grows well at 40 MPa and hence is piezotolerant.

Phyletic Line

The taxonomic status of an actinomycete isolated from sediment collected from the Mariana Trench was established using a combination of genotypic and phenotypic data. Isolate MT8T had chemotaxonomic and morphological properties consistent with its classification in the genus Williamsia, and formed a distinct phyletic line in the 16S rRNA gene tree together with the type strain of Williamsia muralis. The isolate was readily distinguished from the latter, and from representatives of other Williamsia species, using DNA–DNA relatedness and phenotypic criteria. Predominant cellular fatty acids were oleic, palmitic and tuberculostearic acids and a hexadecenoic acid. The DNA G+C content was 65.2 mol%. It is apparent that the isolate belongs to a novel species of Williamsia. Strain MT8T (=DSM 44944T=NCIMB 14085T) was thus considered to be the type strain of a novel species in the genus Williamsia, for which the name Williamsia marianensis sp. nov. is proposed.

Type Strains

The taxonomic positions of two actinobacterial strains isolated from Mariana Trench sediment were established using a combination of genotypic and phenotypic data. The strains, isolates MT2.1T and MT2.2T, formed a distinct phyletic line in the Micrococcineae 16S rRNA gene tree together with Dermacoccus abyssi NCIMB 14084T. The isolates had chemical and phenotypic properties typical of members of the genus Dermacoccus and could be distinguished sharply from one another and from the type strains of Dermacoccus abyssi and Dermacoccus nishinomiyaensis using DNA–DNA relatedness data. A range of phenotypic properties served to distinguish the two novel strains from one another and from the type strains of established Dermacoccus species. The G+C contents of the DNAs of strains MT2.1T and MT2.2T were 66.8 and 69.1 mol%, respectively. It is evident that the two isolates merit recognition as novel species within the genus Dermacoccus. The names proposed for these taxa are Dermacoccus barathri sp. nov. (type strain MT2.1T=DSM 17574T=NCIMB 14081T) and Dermacoccus profundi sp. nov. (type strain MT2.2T=DSM 17575T=NCIMB 14084T).

Phenotypic Data

A polyphasic study was undertaken to determine the taxonomic status of six strains received as Streptomyces hygroscopicus. The strains had chemotaxonomic and morphological properties typical of members of the genus Streptomyces and formed distinct phyletic lines in the Streptomyces 16S rRNA gene tree. These strains were distinguished from one another and from phylogenetically close neighbours using a combination of phenotypic properties. The combined genotypic and phenotypic data showed that all six strains form distinct centres of taxonomic variation within the genus Streptomyces. The following novel species are proposed to accommodate the strains: Streptomyces aldersoniae sp. nov. (type strain DSM 41909T =NRRL 18513T), Streptomyces angustmyceticus sp. nov., comb. nov. (type strain DSM 41683T=NRRL B-2347T), Streptomyces ascomycinicus sp. nov. (type strain DSM 40822T =NBRC 13981T), Streptomyces decoyicus sp. nov., comb. nov. (type strain DSM 41427T =NRRL 2666T), Streptomyces milbemycinicus sp. nov. (type strain DSM 41911T =NRRL 5739T) and Streptomyces wellingtoniae sp. nov. (type strain DSM 40632T =NRRL B-1503T).

The taxonomic position of a marine actinomycete, strain SJS0289/JS1T, was determined using a polyphasic taxonomic approach. The organism, which had phenotypic properties consistent with its classification in the genus Williamsia, formed a distinct clade in the 16S rRNA gene tree together with the type strain of Williamsia muralis, but was readily distinguished from this species using DNA–DNA relatedness and phenotypic data. The genotypic and phenotypic data show that the organism merits recognition as a new species of Williamsia. The name proposed for the new species is Williamsia maris; the type strain is SJS0289/JS1T (=DSM 44693T=JCM 12070T=KCTC 9945T=NCIMB 13945T).

The taxonomic positions of two soil actinomycetes, strains 117T and 43401T, provisionally assigned to the genus Nocardia were determined in a polyphasic study. The organisms were found to have phenotypic properties typical of members of the genus Nocardia, and formed a distinct branch in the Nocardia 16S rRNA gene tree. It was evident from the phylogenetic data that the isolates were most closely, albeit loosely, associated with the type strains of Nocardia nova and Nocardia pseudobrasiliensis. However, all four of these organisms were readily distinguishable from one another using DNA–DNA relatedness and phenotypic data. It is evident from the genotypic and phenotypic data that the two isolates should be recognized as novel species of the genus Nocardia. It is proposed, therefore, that strains 117T (=CGMCC 4.1904T=JCM 12860T) and 43401T (=CGMCC 4.1905T=JCM 12861T) be classified in the genus Nocardia as the type strains of Nocardia miyunensis sp. nov. and Nocardia jiangxiensis sp. nov., respectively.

Seven Gram-positive, coryneform bacteria with virtually identical whole-organism protein patterns were isolated from the surface of smear-ripened cheeses. Representatives of these strains were the subject of a polyphasic study designed to establish their taxonomic status. The organisms formed a distinct branch in the Microbacteriaceae 16S rRNA gene tree and were most closely related to members of the genus Agrococcus, sharing sequence similarities of 95.4–98.7 %. The chemotaxonomic profiles of the strains were consistent with their classification in the genus Agrococcus. The combined genotypic and phenotypic data show that the isolates should be classified in the genus Agrococcus as representatives of a novel species. The name Agrococcus casei sp. nov. is proposed for this taxon. Isolate R-17892t2T (=DSM 18061T=LMG 22410T) is the type strain of Agrococcus casei sp. nov.

The taxonomic positions of three Lechevalieria-like strains isolated from hyperarid soils of the Atacama Desert, Chile, were established by using a polyphasic approach. The organisms had chemical and morphological properties consistent with their classification in the genus Lechevalieria. They formed a distinct subclade in the Lechevalieria 16S rRNA gene clade and were most closely related to the type strain of Lechevalieria xinjiangensis. DNA–DNA relatedness data showed that each of the isolates and Lechevalieria xinjiangensis DSM 45081T belong to distinct genomic species. The new isolates and the type strains of recognized Lechevalieria species were readily distinguished based on a number of phenotypic properties. A combination of the genotypic and phenotypic data showed that the three isolates represent three novel species of the genus Lechevalieria. The names proposed for these taxa are Lechevalieria atacamensis sp. nov. (type strain C61T =CGMCC 4.5536T =NRRL B-24706T), Lechevalieria deserti sp. nov. (type strain C68T =CGMCC 4.5535T =NRRL B-24707T) and Lechevalieria roselyniae sp. nov. (type strain C81T =CGMCC 4.5537T =NRRL B-24708T).

A novel actinomycete, designated strain 06182M-1T, was isolated from a mangrove soil sample collected from Chiayi County in Taiwan. Phylogenetic analysis based on 16S rRNA gene sequences revealed levels of similarity of 97.0–98.8 % to the type strains of recognized species of the genus Isoptericola. Chemotaxonomic data also supported the placement of strain 06182M-1T within the genus Isoptericola. However, the low levels of DNA–DNA relatedness between the novel strain and the type strains of recognized species of the genus Isoptericola, in combination with differential phenotypic data, demonstrate that strain 06182M-1T represents a novel species of the genus Isoptericola, for which the name Isoptericola chiayiensis sp. nov. is proposed. The type strain is 06182M-1T ( = BCRC 16888T  = KCTC 19740T).

Streptomyces Species

The taxonomic status of six neutrotolerant acidophilic streptomycetes isolated from acidic soils in Yunnan Province, China, was established using a polyphasic approach. The morphological and chemotaxonomic characteristics revealed that the isolates belong to the genus Streptomyces. Almost complete 16S rRNA gene sequences of the isolates were determined and aligned with available corresponding sequences of representatives of the family Streptomycetaceae; phylogenetic trees were inferred using four tree-making algorithms. The isolates formed a distinct, albeit heterogeneous, subclade in the Streptomyces 16S rRNA gene tree together with the type strain of Streptomyces yeochonensis, but were readily distinguishable from the latter using DNA–DNA hybridization and phenotypic data. It was evident from the genotypic and phenotypic data that the isolates belonged to four novel Streptomyces species, for which the following names are proposed: Streptomyces guanduensis sp. nov. (type strain 701T=CGMCC 4.2022T=JCM 13274T), Streptomyces paucisporeus sp. nov. (type strain 1413T=CGMCC 4.2025T=JCM 13276T), Streptomyces rubidus sp. nov. (type strain 13c15T=CGMCC 4.2026T=JCM 13277T) and Streptomyces yanglinensis sp. nov. (type strain 1307T=CGMCC 4.2023T=JCM 13275T); isolates 317 and 913 belong to this latter species.

A coryneform strain, 06-1773OT (=WAL 19168T), derived from a groin abscess sample was characterized using phenotypic and molecular taxonomic methods. Comparative analyses revealed more than 3 % divergence of the 16S rRNA gene sequence and about 10 % divergence of the partial rpoB gene sequence from the type strain of Corynebacterium glucuronolyticum. The strain could also be differentiated from C. glucuronolyticum by a set of phenotypic properties. A DNA–DNA relatedness study between strain WAL 19168T and C. glucuronolyticum CCUG 35055T showed a relatedness value of 13.3 % (13.7 % on repeat analysis). The genotypic and phenotypic data show that the strain merits classification within a novel species of Corynebacterium. We propose the name Corynebacterium pyruviciproducens sp. nov. for the novel species. The type strain is 06-1773OT (=WAL 19168T =CCUG 57046T =ATCC BAA-1742T).
