New 16S rRNA signature nucleotide patterns of taxa above the family level are presented and the affiliation of genera to families are indicated and the phylogenetic relationships of Actinobacteria at higher levels may need to be reconstructed.
Bacterial and archaeal diversities in Yunnan and Tibetan hot springs, China.
Findings from this study significantly improve the understanding of microbial diversity in terrestrial hot springs and possessed many phylogenetic lineages that have never been detected in other hot springs in the world.
Amycolicicoccus subflavus gen. nov., sp. nov., an actinomycete isolated from a saline soil contaminated by crude oil.
Chemotaxonomic data indicated that strain DQS3-9A1(T) differs from the present members of the suborder Corynebacterineae, and the creation of Amycolicicoccus subflavus gen. nov., sp.
Diversity of Crenarchaeota in terrestrial hot springs in Tengchong, China
It is shown that temperature may predominate over pH in affecting crenarchaeotal diversity in Tengchong hot springs, indicating that the moderately hot-temperature springs may provide optimal conditions for speciation of Cren archaeota.
Seperation, identification and analysis of pigment (melanin) production in Streptomyces
Nine strains among 180 Streptomyces isolates produce a diffusible dark brown pigment on both peptone-yeast extract agar and synthetic tyrosine-agar. They also show the positive reaction to Ltyrosine…
Prokaryotic systematics in the genomics era
It is expected that taxonomic books, such as Bergey’s Manual of Systematic Bacteriology may evolve into a systematics library indexed by phylogenomic information with an comprehensive understanding of prokaryotic speciation and associated increasing knowledge of biological phenomena.
Description of Sinobacter flavus gen. nov., sp. nov., and proposal of Sinobacteraceae fam. nov.
On the basis of its distinctive phenotypic and genotypic characteristics, strain CW-KD 4(T) represents a new genus and a novel species in the class Gammaproteobacteria, for which the name Sinobacter flavus gen. nov. is proposed.
Sciscionella marina gen. nov., sp. nov., a marine actinomycete isolated from a sediment in the northern South China Sea.
The taxonomic position of an actinomycete isolated from a sediment sample collected from the northern South China Sea was determined by using a polyphasic approach and represents a new genus within the family Pseudonocardiaceae.
Tepidimonas sediminis sp. nov. and Tepidimonas alkaliphilus sp. nov., two novel moderately thermophilic species isolated from a hot spring
Pairwise comparison of the 16S rRNA gene sequences showed that strains YIM 72259T and YIM 72238T are closely related to Tepidimonas ignava SPS-1037T and T. taiwanensis I1-1T, while sharing 98.0% sequence similarity with each other.
Haloactinospora alba gen. nov., sp. nov., a halophilic filamentous actinomycete of the family Nocardiopsaceae.
A novel halophilic, filamentous, actinomycete strain, isolated from a salt lake in Xinjiang Province, north-west China, and subjected to a polyphasic taxonomic study indicated that strain YIM 90648(T) formed a distinct lineage within the family Nocardiopsaceae and showed 16S rRNA gene sequence similarity of 93.3-95.0%.
