| clarification of the relationship between the members of the family thermomonosporaceae on the basis of 16s rdna, 16s-23s rrna internal transcribed spacer and 23s rdna sequences and chemotaxonomic analyses. | to resolve relationships between members of the family thermomonosporaceae, phylogenetic analyses using three sets of nucleotide sequences from 16s rdna, 23s rdna and the 16s-23s internal transcribed spacer (its) were carried out. nearly all species of the family were included in this study. on the basis of congruous phylogenetic results and chemotaxonomic data, the following proposals are made. first, actinomadura libanotica, actinomadura aurantiaca, actinomadura glomerata and actinomadura long ... | 2001 | 11321082 |
| 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 |
| [the application of succession analysis in combination with extremely high-frequency irradiation to the selective isolation of actinomycetes from soil]. | a new method employing succession analysis and extremely high-frequency (ehf) irradiation is proposed for the selective isolation of actinomycetes from soil. total actinomycetes were efficiently isolated from soil suspensions irradiated in the wavelength band 4.6-5.8 mm on the 14th and 45th days of succession initiated by soil wetting and from soil suspensions irradiated in the wavelength band 8-11.5 mm on the 7th day of succession. the rare actinomycete genera actinomadura, micromonospora, nono ... | 2003 | 12698804 |
| numerical phenetic classification of clinically significant aerobic sporoactinomycetes and related organisms. | clinically significant aerobic sporoactinomycetes, notably agents of mycetoma, were examined for a balanced set of unit characters and the resultant data analysed using standard numerical taxonomic procedures. all save two of the one hundred and seventy three tested strains were assigned to three multimembered cluster-groups, which encompassed sixteen major (4-7 strains), ten minor (2-3 strains) and forty single membered clusters, in an analysis based on the simple matching coefficient and unwei ... | 2003 | 12906361 |
| actinocorallia cavernae sp. nov., isolated from a natural cave in jeju, korea. | a novel actinomycete, strain n3-7t, was isolated from a natural cave in jeju, republic of korea, using a dilution method and was subjected to characterization using polyphasic taxonomy. a 16s rrna gene sequence analysis revealed that the organism belonged to the phylogenetic cluster of the genus actinocorallia and was most closely related to actinocorallia glomerata and actinocorallia longicatena (97.6 and 97.5 % similarity, respectively). the main chemotaxonomic properties of strain n3-7t, such ... | 2006 | 16627659 |
| classification of 'sarraceniospora aurea' furihata et al. 1989 as actinocorallia aurea sp. nov. | phylogenetic analysis of 'sarraceniospora aurea' nbrc 14752 and strain nbrc 15120, based on 16s rrna gene sequences, revealed that these organisms are related to members of the genus actinocorallia. these organisms contained glutamic acid, alanine and meso-diaminopimelic acid as cell-wall amino acids and the menaquinones mk-9(h(4)), mk-9(h(6)) and mk-9(h(8)). the chemotaxonomic characteristics of the strains were consistent with those of the genus actinocorallia. however, dna-dna hybridization a ... | 2007 | 17766870 |
| rare actinomycete bacteria from the shallow water sediments of the trondheim fjord, norway: isolation, diversity and biological activity. | actinomycete bacteria produce a wide variety of secondary metabolites with diverse biological activities, some of which have been developed for human medicine. rare actinomycetes are promising sources in search for new drugs, and their potential for producing biologically active molecules is poorly studied. in this work, we have investigated the diversity of actinomycetes in the shallow water sediments of the trondheim fjord (norway). due to the use of different selective isolation methods, an u ... | 2007 | 17922759 |
| isolation, diversity, and antimicrobial activity of rare actinobacteria from medicinal plants of tropical rain forests in xishuangbanna, china. | endophytic actinobacteria are relatively unexplored as potential sources of novel species and novel natural products for medical and commercial exploitation. xishuangbanna is recognized throughout the world for its diverse flora, especially the rain forest plants, many of which have indigenous pharmaceutical histories. however, little is known about the endophytic actinobacteria of this tropical area. in this work, we studied the diversity of actinobacteria isolated from medicinal plants collect ... | 2009 | 19648362 |
