| biosynthetic potential of phylogenetically unique endophytic actinomycetes from tropical plants. | the culturable diversity of endophytic actinomycetes associated with tropical, native plants is essentially unexplored. in this study, 123 endophytic actinomycetes were isolated from tropical plants collected from several locations in papua new guinea and mborokua island, solomon islands. isolates were found to be prevalent in roots but uncommon in leaves. initially, isolates were dereplicated to the strain level by ribotyping. subsequent characterization of 105 unique strains by 16s rrna gene s ... | 2010 | 20472734 |
| planotetraspora kaengkrachanensis sp. nov. and planotetraspora phitsanulokensis sp. nov., isolated from soil. | two novel bacterial strains were isolated from tropical rain forest soil from thailand. strains a-t 0875(t) and a-t 1383(t) stained gram-positive and were filamentous bacteria that developed cylindrical sporangia containing four oval- to rod-shaped spores at the ends of short sporangiophores on branched aerial mycelium. the cell-wall peptidoglycan contained meso-diaminopimelic acid, glutamic acid and alanine as cell-wall amino acids; whole-cell hydrolysates contained rhamnose, madurose, glucose, ... | 2010 | 19837735 |
| [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 |
| planotetraspora thailandica sp. nov., isolated from soil in thailand. | a gram-positive-staining, filamentous bacterial strain that developed cylindrical sporangia containing four oval- to rod-shaped spores at the ends of short sporangiophores on branched aerial mycelium was isolated from tropical rainforest soil near a hot spring. the cell-wall peptidoglycan contained meso-diaminopimelic acid, glutamic acid and alanine as cell-wall amino acids; the whole-cell hydrolysate contained rhamnose, madurose, glucose, galactose and 3-o-methylmannose as whole-cell sugars. th ... | 2009 | 19406780 |
| isolation of novel bacteria and actinomycetes using soil-extract agar medium. | novel bacteria were discovered using an isolation technique consisting of (i) selection of microorganisms that grew on soil-extract agar medium, but not on conventional media, and (ii) detection of small microbial colonies with a microscope. three bacterial strains thus isolated were provisionally designated shinshu-th1, -th2, -th 3, and five actinomycete strains, shinshu-ms-01, -02, -03, -04, -05, respectively. sequence analysis of their 16s rdna showed that th1 had 95--96% homology with three ... | 2005 | 16233821 |
| planotetraspora silvatica sp. nov. and emended description of the genus planotetraspora. | an actinomycete that developed sporangia containing four spores in a single row at the ends of short sporangiophores on branched aerial hyphae was isolated from subtropical forest soil. the isolate contained menaquinone mk-9(h(4)), glutamic acid, alanine and meso-diaminopimelic acid as cell-wall amino acids and madurose in the whole-cell hydrolysate. the 16s rrna gene sequence indicated that the isolate formed a monophyletic cluster with planotetraspora mira. on the basis of morphological and ch ... | 2004 | 15545433 |
| cell wall teichoic acids of actinomycetes of three genera of the order actinomycetales. | the structures of cell wall teichoic acids of the members of newly recognized genera of the order actinomycetales were studied. planotetraspora mira vkm ac-2000t contains two types of teichoic acids: 2,3-poly(glycerol phosphate) substituted with alpha-d-galp at c-1 of glycerol and 1,3-poly(glycerol phosphate) substituted with alpha-l-rhap at oh-2 of glycerol (60%). herbidospora cretacea vkm ac-1997t contains the chains of 1,3-poly(glycerol phosphate) partially substituted with alpha-d-galp and a ... | 2002 | 12139476 |
