| poplar clones of different sizes, grown on a heavy metal polluted site, are associated with microbial populations of varying composition. | we performed a field trial to evaluate the response of different poplar clones to heavy metals. we found that poplar plants of the same clone, propagated by cuttings, had a marked variability of survival and growth in different zones of the field that were characterized by very similar physical-chemical prosperities. since metal uptake and its accumulation by plants can be affected by soil microorganisms, we investigated soil microbial populations that were collected in proximity to the roots of ... | 2012 | 22475220 |

| chryseobacterium piscicola sp. nov., isolated from diseased salmonid fish. | eight bacterial strains isolated from diseased rainbow trout (n=5) and atlantic salmon (n=3) were characterized by phenotypic and molecular taxonomic methods. the isolates were negative for the gram-reaction, non-motile, rod-shaped and catalase- and oxidase-positive. colonies on solid media were yellow, smooth, shiny and circular with regular edges. growth occurred at 4-28 degrees c (optimum, 15 degrees c) and with 0-3 % nacl (optimum, 0.5 %). analysis of the 16s rrna gene sequence allocated the ... | 2009 | 19643904 |
| chryseobacterium gregarium sp. nov., isolated from decaying plant material. | in this study, strain p 461/12t, isolated from decaying plant material after mulching a pasture, was shown to represent a novel species of the genus chryseobacterium by means of a polyphasic approach. the closest phylogenetic neighbours to the novel strain, as determined by 16s rrna gene sequence analysis, were chryseobacterium daeguense k105t and chryseobacterium soldanellicola psd1-4t with gene sequence similarities of 97.4 % and 97.2 %, respectively. strain p 461/12t could be differentiated b ... | 2008 | 18450690 |
| chryseobacterium aquaticum sp. nov., isolated from a water reservoir. | strains 10-46(t) and 10-106 were isolated from a water reservoir in korea. they were gram-negative, non-motile, non-spore-forming rods, produced yellow-pigmented colonies on nutrient agar, contained mk-6 as the predominant menaquinone and 15 : 0 iso and 17 : 0 iso 3-oh as the major fatty acids and had polar lipid profiles consisting of phosphatidylethanolamine and several unknown aminolipids. phylogenetic analysis, based on 16s rrna gene sequencing, showed that the strains were closely related t ... | 2008 | 18319450 |
| chryseobacterium soldanellicola sp. nov. and chryseobacterium taeanense sp. nov., isolated from roots of sand-dune plants. | two gram-negative, yellow-pigmented bacteria designated psd1-4t and pha3-4t, isolated from two sand-dune plant species inhabiting coastal areas in tae-an, korea, were subjected to taxonomic investigation. 16s rrna gene sequence analysis indicated that both isolates should be placed in the genus chryseobacterium of the family flavobacteriaceae. the phenotypic properties of the strains were also consistent with their classification into this genus. the levels of 16s rrna gene sequence similarity b ... | 2006 | 16449453 |
