| [ultrastructural organization and development cycle of soil ultramicrobacteria belonging to the class alphaproteobacteria]. | gram-negative chemoorganotrophic soil ultramicrobacteria (umb), strains nf1 and nf3, have been isolated. in their development cycle, the strains formed small coccoid cells of 400-800 nm and ultrasmall cells of 200-300 nm. phylogenetically, the strains nf1 and nf3 belong to alphaproteobacteria and are close to the type strain of the recently described species kaistia adipata. the ultrastructure of umb cells has been studied using ultrathin sections and freeze-fracturing. it has been shown that th ... | 2007 | 18069326 |
| [study of ectoparasitism of ultramicrobacteria of the genus kaistia, strains nf1 and nf3 by electron and fluorescence microscopy]. | transmission electron and fluorescence microscopy was used to study the character of the interaction of free-living ultramicrobacterial (umb) strains nf1 and nf3, affiliated with the genus kaistia, and seven species of gram-positive and gram-negative heterotrophic bacteria. strains nf1 and nf3 were found to exhibit parasitic activity against gram-positive bacillus subtilis and gram-negative acidovorax delafildii. umb cells are tightly attached to the envelopes of the victim cells and induce thei ... | 2008 | 18365722 |
| kaistia soli sp. nov., isolated from a wetland in korea. | a bacterial strain, 5yn9-8(t), was isolated from a peat layer in yongneup, republic of korea. it was strictly aerobic, gram-negative, non-motile, short rod- or coccus-shaped and produced ivory-pigmented colonies. results of 16s rrna gene sequence analyses indicated a close relationship between this isolate and kaistia granuli ko04(t) (97.2 % similarity) and kaistia adipata chj404(t) (96.2 % similarity), members of the order rhizobiales within the alphaproteobacteria. predominant cellular fatty a ... | 2008 | 18599687 |
| pseudoxanthobacter soli gen. nov., sp. nov., a nitrogen-fixing alphaproteobacterium isolated from soil. | a gram-type negative or variable, aerobic, rod-shaped, nitrogen-fixing bacterium, designated strain cc4(t), was isolated on nutrient agar from a soil sample collected at a regional agricultural research field station located in kaohsiung county, taiwan. 16s rrna gene sequence analysis demonstrated that this isolate is unique, showing <92.5 % similarity with respect to species of the genera xanthobacter (maximum of 92.2 % similarity), prosthecomicrobium (92.0 %), devosia (91.9 %), kaistia (91.9 % ... | 2008 | 18599697 |
| a cytological characterization of the parasitic action of ultramicrobacteria nf1 and nf3 of the genus kaistia on chemoorganotrophic and phototrophic bacteria. | two strains (nf1 and nf3) of free-living chemoorganotrophic bacteria have been isolated from multiyear oil slime and pedilanthus tithymaloides rhizosphere and ascribed to the genus kaistia of the class alphaproteobacteria on the basis of the nucleotide sequences of 16s rrna gene and phenotypic characteristics. these strains can be assigned to ultramicrobacteria as their populations are represented by two subpopulations: (1) ultrasmall cells, on average 200-300 nm in diameter and <0.1 microm(3) i ... | 2009 | 19486154 |
| kaistia terrae sp. nov., isolated from a wetland in korea. | an ivory-coloured bacterium, designated strain 5yn7-3(t), was isolated from a wetland, yongneup, korea. cells of the strain were aerobic, gram-stain-negative, non-motile and short rods. 16s rrna gene sequence analysis demonstrated that strain 5yn7-3(t) belongs to the order rhizobiales of the class alphaproteobacteria and is closely related to kaistia soli 5yn9-8(t) (97.8 %), kaistia granuli ko04(t) (97.6 %) and kaistia adipata chj404(t) (97.4 %). strain 5yn7-3(t) showed dna-dna hybridization val ... | 2010 | 19661503 |
| reclassification of the polyphyletic genus prosthecomicrobium to form two novel genera, vasilyevaea gen. nov. and bauldia gen. nov. with four new combinations: vasilyevaea enhydra comb. nov., vasilyevaea mishustinii comb. nov., bauldia consociata comb. nov. and bauldia litoralis comb. nov. | species of the genus prosthecomicrobium are noted for their numerous cellular appendages or prosthecae that extend from the cells. this investigation confirms that the genus is polyphyletic based on an extensive analysis of the 16s rrna gene sequences of several named species of the genus. the analyses indicate that some prosthecomicrobium species are more closely related to non-prosthecate genera, including devosia, labrenzia, blastochloris, methylosinus, mesorhizobium and kaistia, than they ar ... | 2010 | 20118292 |
