Forty one strains isolated from 21 samples of various mushroom composts in Korea were analyzed by 16S rRNA gene sequencing to investigate the phylogenetic diversity of thermophilic actinomycetes. The 25 strains of thermophilic actinomycete isolates were related to the five genera, Pseudonocardia, Saccharomonospora, Saccharopolyspora, Streptomyces, and Thermobifida, within the order Actinomycetales, and 16 strains were classified into the genus Thermoactinomyces within the family Bacillaceae… 

Phylogenetic analysis of Streptomyces spp. isolated from potato scab lesions in Korea on the basis of 16S rRNA gene and 16S-23S rDNA internally transcribed spacer sequences.

It was clarified that ITS regions are not useful in phylogenetic analysis of Streptomyces spp.

Prevalence of Thermoactinomyces thalpophilus and T. sacchari strains with biotechnological potential at hot springs and soils from West Anatolia in Turkey

It is suggested that the thermophilic actinomycetes, which are a part of the biodiversity of the hot springs and soils from West Anatolia in Turkey, are promising sources for novel enzymes and antimicrobial compounds.

Planifilum fimeticola gen. nov., sp. nov. and Planifilum fulgidum sp. nov., novel members of the family 'Thermoactinomycetaceae' isolated from compost.

DNA-DNA hybridization showed that the isolates could be divided into two genomic groups, strain H0165(T) and the other three strains, which indicated that the four isolates should be classified into two species of a novel genus in the family 'Thermoactinomycetaceae', for which the names Planifilum fimeticola gen. nov., sp.nov.

Rapid discrimination of potato scab-causing Streptomyces species based on the RNase P RNA gene sequences

Results revealed that the rnpB gene could be used as a powerful taxonomic tool for rapid differentiation of closely related Streptomyces species, and it was suggested that the variable regions marked as α, β, γ, and δ in the rNPB genes could be useful markers for the detection of specific Streptomeces species.

Extremophilic and extremotolerant actinomycetes in different soil types

The regularities of the distribution of extremophilic and extremotolerant actinomycetes developing in unusual for mycelial bacteria conditions, their structural-functional characteristics, and their taxonomic composition were determined.

From phylogenetic analysis based on 16S rDNA sequences, it is suggested that the genus Thermoactinomyces should be taxonomically re-evaluated using other useful taxonomic markers.

Streptomyces thermocarboxydovorans sp. nov. and Streptomyces thermocarboxydus sp. nov., two moderately thermophilic carboxydotrophic species from soil.

The molecular systematic evidence, together with phenotypic data derived from this and previous studies, indicate that the test strains merit species status within the genus Streptomyces.

Classification of thermophilic streptomycetes, including the description of Streptomyces thermoalcalitolerans sp. nov.

The genotypic and phenotypic data clearly show that Streptomyces thermonitrificans Desai and Dhala 1967 and S. thermovulgaris represent a single species, and 10 out of the 11 representative thermophilic alkalitolerant isolates had a combination of properties consistent with their classification as S. thermodiastaticus.

A phylogenetic analysis of the genus Nocardia with 16S rRNA gene sequences.

The results of isoprenoid quinone analyses provided evidence that nocardiae can be distinguished from all other actinomycete taxa on the basis of their characteristic menaquinone profiles.

Thermocrispum gen. nov., a new genus of the order Actinomycetales, and description of Thermocrispum municipale sp. nov. and Thermocrispum agreste sp. nov.

Ten strains of thermophilic actinomycetes were isolated from waste and mushroom composts, as well as from the air of compost plants and a refuse incineration plant in Germany, and indicated that this new genus is closely related to members of the family Pseudonocardiaceae and related taxa and contains two species.

A phylogenetic analysis of the genus Saccharomonospora conducted with 16S rRNA gene sequences.

Nearly complete sequences of 16S rRNA genes of representative strains of the genus Saccharomonospora were determined following the isolation and cloning of the amplified genes, and a phylogenetic tree was inferred by the neighbor-joining method.

In the present study, the Nocardia-Rhodococcus group and the Saccharothrix-Actinokineospora group were both recovered within the clade for the family Pseudonocardiaceae, indicating a close phylogenetic relationship between the genera Amycolata and Pseud onocardia.

A Taxonomic Study of Thermomonospora and Other Monosporic Actinomycetes

Only five strains of Thermoactinomyces were included, but they formed a cluster with an internal structure which supported a previous numerical classification of species in this genus, and five Thermomonospora spp.

Distinct Types of rRNA Operons Exist in the Genome of the Actinomycete Thermomonospora chromogena and Evidence for Horizontal Transfer of an Entire rRNA Operon

The presence of two distinct types of rRNA operons in the genome of a thermophilic actinomycete Thermomonospora chromogena is described and it is proposed that T.chromogena acquired rrnB operon from T. bispora or a related organism via horizontal gene transfer.

Methanogen and bacterial diversity and distribution in deep gas hydrate sediments from the Cascadia Margin as revealed by 16S rRNA molecular analysis.

A bacteria and methanogen community of limited diversity is shown and it is confirmed that the gas hydrate zone is biogeochemically active, suggesting that the methane hydrate at this site is at least partially biogenic in origin.
