| nitrogen fixation in asaia sp. (family acetobacteraceae). | the genus asaia (family acetobacteraceae) was first introduced with a single species-asaia bogorensis and later six more species were described namely a. siamensis, a. krungthepensis, a. lannaensis, a. platycodi, a. prunellae, and a. astilbes. acetobacteraceae family has been divided into ten genera but, only three of them include nitrogen fixing species: gluconacetobacter, acetobacter, and swaminathania. this article originated from our study primarily aimed to isolate new endosymbiotic nitroge ... | 2011 | 21681635 |
| recent advances in nitrogen-fixing acetic acid bacteria. | nitrogen is an essential plant nutrient, widely applied as n-fertilizer to improve yield of agriculturally important crops. an interesting alternative to avoid or reduce the use of n-fertilizers could be the exploitation of plant growth-promoting bacteria (pgpb), capable of enhancing growth and yield of many plant species, several of agronomic and ecological significance. pgpb belong to diverse genera, including azospirillum, azotobacter, herbaspirillum, bacillus, burkholderia, pseudomonas, rhiz ... | 2008 | 18177965 |
| ecological occurrence of gluconacetobacter diazotrophicus and nitrogen-fixing acetobacteraceae members: their possible role in plant growth promotion. | gluconacetobacter diazotrophicus has a long-standing history of bacterial-plant interrelationship as a symbiotic endophyte capable of fixing atmospheric nitrogen. in low nitrogen fertilized sugarcane fields it plays a significant role and its occurrence was realised in most of the sugarcane growing countries. in this mini review, the association of g. diazotrophicus with sugarcane, other crop plants and with various hosts is discussed. the factors affecting survival in the rhizosphere and the pu ... | 2008 | 17574542 |
| phylogenetic relationships between the genera swaminathania and asaia, with reference to the genera kozakia and neoasaia, based on 16s rdna, 16s-23s rdna its, and 23s rdna sequences. | | 2006 | 17310072 |
| neoasaia chiangmaiensis gen. nov., sp. nov., a novel osmotolerant acetic acid bacterium in the alpha-proteobacteria. | an acetic acid bacterium, designated as isolate ac28(t), was isolated from a flower of red ginger (khing daeng in thai; alpinia purpurata) collected in chiang mai, thailand, at ph 3.5 by use of a glucose/ethanol/acetic acid (0.3%, w/v) medium. a phylogenetic tree based on 16s rrna gene sequences for 1,376 bases showed that isolate ac28(t) constituted a cluster along with the type strain of kozakia baliensis. however, the isolate formed an independent cluster in a phylogenetic tree based on 16s-2 ... | 2005 | 16314684 |
| swaminathania salitolerans gen. nov., sp. nov., a salt-tolerant, nitrogen-fixing and phosphate-solubilizing bacterium from wild rice (porteresia coarctata tateoka). | a novel species, swaminathania salitolerans gen. nov., sp. nov., was isolated from the rhizosphere, roots and stems of salt-tolerant, mangrove-associated wild rice (porteresia coarctata tateoka) using nitrogen-free, semi-solid lgi medium at ph 5.5. strains were gram-negative, rod-shaped and motile with peritrichous flagella. the strains grew well in the presence of 0.35% acetic acid, 3% nacl and 1% kno3, and produced acid from l-arabinose, d-glucose, glycerol, ethanol, d-mannose, d-galactose and ... | 2004 | 15280289 |
| genera and species in acetic acid bacteria. | taxonomic studies of acetic acid bacteria were historically surveyed. the genus acetobacter was first introduced in 1898 with a single species, acetobacter aceti. the genus gluconobacter was proposed in 1935 for strains with intense oxidation of glucose to gluconic acid rather than oxidation of ethanol to acetic acid and no oxidation of acetate. the genus "acetomonas" was described in 1954 for strains with polar flagellation and no oxidation of acetate. the proposals of the two generic names wer ... | 2008 | 18199517 |
| tanticharoenia sakaeratensis gen. nov., sp. nov., a new osmotolerant acetic acid bacterium in the alpha-proteobacteria. | tanticharoenia sakaeratensis gen. nov., sp. nov. is proposed for three strains isolated from soil collected in thailand. the three strains, ac37(t), ac38, and ac39, were included within a lineage comprising the genera asaia, kozakia, swaminathania, neoasaia, acetobacter, gluconobacter, and saccharibacter in a phylogenetic tree based on 16s rrna gene sequences, but formed a quite different, independent cluster. pair-wise sequence similarities of strain ac37(t) were 96.5-92.1% to the type strains ... | 2008 | 18323667 |
| ameyamaea chiangmaiensis gen. nov., sp. nov., an acetic acid bacterium in the alpha-proteobacteria. | two isolates, ac04(t) and ac05, were isolated from the flowers of red ginger collected in chiang mai, thailand. in phylogenetic trees based on 16s rrna gene sequences, the two isolates were included within a lineage comprised of the genera acidomonas, gluconacetobacter, asaia, kozakia, swaminathania, neoasaia, granulibacter, and tanticharoenia, and they formed an independent cluster along with the type strain of tanticharoenia sakaeratensis. the calculated pair-wise sequence similarities of isol ... | 2009 | 19809199 |
