| streptacidiphilus gen. nov., acidophilic actinomycetes with wall chemotype i and emendation of the family streptomycetaceae (waksman and henrici (1943)al) emend. rainey et al. 1997. | the taxonomic position of acidophilic actinomycetes selectively isolated from acidic soils and litter was examined using a polyphasic approach. the distinct 16s rdna phyletic branch formed by representative strains was equated with related monophyletic clades that corresponded to the genera kitasatospora and streptomyces. the acidophilic isolates also exhibited a distinctive ph profile, a unique 16s rdna signature, and contained major amounts of ll-diaminopimelic acid, galactose and rhamnose in ... | 2003 | 12785304 |
| streptacidiphilus jiangxiensis sp. nov., a novel actinomycete isolated from acidic rhizosphere soil in china. | the taxonomic position of three acidophilic actinomycetes isolated from acidic rhizosphere soil was established using a polyphasic approach. the morphological and chemical properties of the isolates were found to be consistent with their assignment to the genus streptacidiphilus. almost complete 16s rrna gene sequences determined for the strains were aligned with corresponding sequences of representatives of the genera kitasatospora, streptacidiphilus and streptomyces and phylogenetic trees infe ... | 2004 | 15280649 |
| streptacidiphilus oryzae sp. nov., an actinomycete isolated from rice-field soil in thailand. | the taxonomic position of ten acidophilic actinomycetes isolated from an acidic rice-field soil was established using a polyphasic approach. 16s rrna gene sequences determined for the isolates were aligned with corresponding sequences of representatives of the genera kitasatospora, streptacidiphilus and streptomyces and phylogenetic trees were inferred using four tree-making algorithms. the isolates had identical sequences and formed a distinct branch at the periphery of the streptacidiphilus 16 ... | 2006 | 16738101 |
| phylogenetic diversity of acidophilic sporoactinobacteria isolated from various soils. | spore forming actinobacteria (sporoactinobacteria) isolated from soils with an acidic ph in pinus thunbergii forests and coal mine waste were subjected to taxonomic characterization. for the isolation of acidophilic actinobacteria, acidified starch casein agar (ph adjusted to 4-5) was used. the numbers of actinobacteria growing in acidic media were between 3.2 x 10(4) and 8.0 x 10(6) cfu/g soil. forty three acidophilic actinobacterial strains were isolated and their 16s rdna sequences were deter ... | 2006 | 17205037 |
| streptacidiphilus anmyonensis sp. nov., streptacidiphilus rugosus sp. nov. and streptacidiphilus melanogenes sp. nov., acidophilic actinobacteria isolated from pinus soils. | the taxonomic positions of 22 spore-forming, extensively branched actinobacteria isolated from pinus soils were examined using a polyphasic approach. analysis of the 16s rrna gene sequences indicated that all of the isolates fell into three distinctive phylogenetic clusters within the genus streptacidiphilus of the family streptomycetaceae, and also that streptacidiphilus jiangxiensis was the species closest to the three phyloclusters, with 16s rrna gene sequence similarities ranging from 98.0 t ... | 2008 | 18599696 |
| [selective isolation and diversity of acidophilic filamentous actinomycetes from acidic soils]. | to establish effective methods for selective isolation of acidophilic filamentous actinomycetes from acidic soils, and to investigate their genus and species diversity. | 2009 | 19673405 |
| polyhydroxyalkanoates production by actinobacteria isolated from soil. | polyhydroxyalkanoates (phas) are biodegradable and renewable polymers produced by a wide range of bacterial groups. new microbial bioprospection approaches have become an important way to find new pha producers and new synthesized polymers. over the past years, bacteria belonging to actinomycetes group have become known as pha producers, such as nocardia and rhodococcus species, kineosphaera limosa liu et al. 2002, and, more recently, streptomyces species. in this paper, we disclose that there a ... | 2009 | 19767851 |
