| antifreeze protein activity in arctic cryoconite bacteria. | fourteen arctic bacterial strains belonging to five genera, cryobacterium, leifsonia, polaromonas, pseudomonas, and subtercola isolated from sediments found in cryoconite holes of arctic glaciers, were subjected to screening for antifreeze proteins (afps). eight strains showed afp activity, and six strains of four species were further characterized. pseudomonas ficuserectae exhibited a high thermal hysteresis (th) activity. ice recrystallization inhibition (iri) activity was observed in most cul ... | 2014 | 24283367 |
| pseudomonas cerasi sp. nov. (non griffin, 1911) isolated from diseased tissue of cherry. | eight isolates of gram-negative fluorescent bacteria (58(t), 122, 374, 791, 963, 966, 970a and 1021) were obtained from diseased tissue of cherry trees from different regions of poland. the symptoms resembled those of bacterial canker. based on an analysis of 16s rdna sequences the isolates shared the highest over 99.9% similarity with pseudomonas ficuserectae jcm 2400(t) and p. congelans dsm 14939(t). phylogenetic analysis using housekeeping genes gyrb, rpod and rpob revealed that they form a s ... | 2016 | 27283223 |
| high-performance liquid chromatography analyses of pyoverdin siderophores differentiate among phytopathogenic fluorescent pseudomonas species. | the relationship of pyoverdins produced by 41 pathovars of pseudomonas syringae and by phytopathogenic pseudomonas species was investigated. a high-performance liquid chromatography method for analyzing the culture medium proved to be superior to isoelectric focusing for detecting pyoverdin production, for differentiating slightly different pyoverdins, and for differentiating atypical from typical fe(iii)-chelated pyoverdins. nonfluorescent strains were found in pseudomonas amygdali, pseudomonas ... | 2003 | 12571041 |
| taxonomic implications of synthesis of poly-beta-hydroxybutyrate and other poly-beta-hydroxyalkanoates by aerobic pseudomonads. | whereas poly-beta-hydroxybutyrate (phb) production by pseudomonas species is rare, synthesis of medium-chain-length poly-beta-hydroxyalkanoates (mcl-phas) other than phb, has been observed in fluorescent and non-fluorescent species. contrary to original reports, pseudomonas corrugata and pseudomonas ficuserectae accumulate mcl-phas and not phb. the taxonomic implications of these characteristics are discussed. | 2000 | 10758879 |
| dna relatedness among the pathovars of pseudomonas syringae and description of pseudomonas tremae sp. nov. and pseudomonas cannabina sp. nov. (ex sutic and dowson 1959). | a total of 48 pathovars of pseudomonas syringae and eight related species were studied by dna-dna hybridization (s1 nuclease method) and ribotyping. the existence of nine discrete genomospecies was indicated. genomospecies 1 corresponded to p. syringae sensu stricto and included p. syringae pathovars syringae, aptata, lapsa, papulans, pisi, atrofaciens, aceris, panici, dysoxyli and japonica. genomospecies 2 included p. syringae pathovars phaseolicola, ulmi, mori, lachrymans, sesami, tabaci, mors ... | 1999 | 10319466 |
