Some strains of the former genus Agrobacterium have high biotechnological interest and are currently misclassified. Consequently, in this study, the taxonomic status of the non-pathogenic strain Agrobacterium radiobacter K84, used in biological control, and the tumourigenic strain Agrobacterium tumefaciens AKE10, able to regenerate tobacco transgenic(More)
The genus Pseudomonas was described in 1894 and is one of the most diverse and ubiquitous bacterial genera whose species have been isolated worldwide in all kinds of environments, from the Antarctica to the Tropics, present in sediments, clinical samples, plant, fungi and diseased animal specimens, water, soil, plant rhizosphere, sea, deserts, etc. The(More)
The species Phaseolus vulgaris is a promiscuous legume nodulated by several species of the family Rhizobiaceae. During a study of rhizobia nodulating this legume in Portugal, we isolated several strains that nodulate P. vulgaris effectively and also Macroptilium atropurpureum and Leucaena leucocephala, but they form ineffective nodules in Medicago sativa.(More)
The species Lactococcus lactis currently includes three subspecies; L. lactis subsp. lactis and L. lactis subsp. cremoris, isolated from milk sources, and L. lactis subsp. hordniae, isolated from the leafhopper Hordnia circellata. In this study, three strains, designated L105(T), I3 and L101, were isolated from the intestinal mucus of brown trout (Salmo(More)
During a study of polysaccharide-hydrolysing bacteria present in different plant sources, two strains were isolated from pulverized decaying wood of Populus alba and classified in the genus Rhizobium on basis of their almost complete 16S rRNA gene sequences. Their closest phylogenetic relatives were Rhizobium galegae USDA 4128(T) and Rhizobium huautlense(More)
A Gram-negative, non-spore-forming bacterial strain with the ability to solubilize highly insoluble phosphatic minerals was isolated from a high-phosphorous iron ore from Minas Gerais State, Brazil. This strain, designated FeGl01(T), was subjected to a polyphasic taxonomic investigation. Comparative 16S rRNA gene sequence analysis indicated that it formed a(More)
A bacterial strain, designated Ch-32(T), was isolated from the phyllosphere of Castanea sativa in Spain. Phylogenetic analysis based on 16S rRNA gene sequences placed the isolate in the genus Paenibacillus within the same subgroup as Paenibacillus xinjiangensis and Paenibacillus glycanilyticus, with similarities of 96.3 and 96.8 %, respectively. DNA-DNA(More)
Members of the species Agrobacterium ferrugineum were isolated from marine environments. The type strain of this species (= LMG 22047(T) = ATCC 25652(T)) was recently reclassified in the new genus Pseudorhodobacter, in the order 'Rhodobacterales' of the class 'Alphaproteobacteria'. Strain LMG 128 (= ATCC 25654) was also initially classified as belonging to(More)
Several strains isolated from Cytisus villosus nodules have been characterized based on their diverse genetic, phenotypic and symbiotic characteristics. According to 16S rRNA gene sequence analysis, the isolates formed a group that was closely related to Bradyrhizobium canariense BTA-1(T) with 99.4% similarity. Analysis of three housekeeping genes, recA,(More)
In this paper we analyze through a polyphasic approach several Bradyrhizobium strains isolated in Spain and Morocco from root nodules of Retama sphaerocarpa and Retama monosperma. All the strains have identical 16S rRNA genes and their closest relative species is Bradyrhizobium lablabi CCBAU 23086(T), with 99.41% identity with respect to the strain Ro19(T).(More)
