transfer and expression of pseudomonas plasmid rp1 in caulobacter.this study demonstrates that the host range of pseudomonas plasmid rp1 includes the genus caulobacter. caulobacter was shown to acquire three antibiotic resistance markers located in rp1. a fourth plasmid marker, susceptibility to an rna bacteriophage, was not expressed, but could be transferred from caulobacter to escherichia coli. the lack of phenotypic expression of the phage marker was manifested by the inability of the phage to adsorb or to produce plaques on caulobacter transcipients. mati ...1977406354
pilus-dependent, double-stranded dna bacteriophage for caulobacter.caulobacter phage phi 6, previously reported to adsorb specifically to bacterial flagella, was shown here to attach to pili more frequently than to flagella. phage phi 6 was shown to contain double-stranded dna by circular dichroism spectroscopy and thermal denaturation accompanied by a hyperchromic shift at 260 nm. morphologically, phage phi 6 fits group b2 (h.-w. ackermann, in a. i. laskin and h. a. lechevalier, ed., handbook of microbiology, vol. 1, p. 638-643, 1973) with a long, noncontracti ...19806106721

the phylogenetic relationships of caulobacter, asticcacaulis and brevundimonas species and their taxonomic implications.the phylogenetic relationships among the species of caulobacter, asticcacaulis and brevundimonas were studied by comparison of their 16s rdna sequences. the analysis of almost complete sequences confirmed the early evolutionary divergence of the freshwater and marine species of caulobacter reported previously [stahl, d. a., key, r., flesher, b. & smit, j. (1992). j bacteriol 174, 2193-2198]. the freshwater species formed two distinct clusters. one cluster contained the species caulobacter bacter ...199910319468
phylogeny and polyphasic taxonomy of caulobacter species. proposal of maricaulis gen. nov. with maricaulis maris (poindexter) comb. nov. as the type species, and emended description of the genera brevundimonas and caulobacter.the genus caulobacter is composed of prosthecate bacteria often specialized for oligotrophic environments. the taxonomy of caulobacter has relied primarily upon morphological criteria: a strain that visually appeared to be a member of the caulobacter has generally been called one without challenge. a polyphasic approach, comprising 16s rdna sequencing, profiling restriction fragments of 16s-23s rdna interspacer regions, lipid analysis, immunological profiling and salt tolerance characterizations ...199910425763

postgenomic scan of metallo-beta-lactamase homologues in rhizobacteria: identification and characterization of bjp-1, a subclass b3 ortholog from bradyrhizobium japonicum.the diffusion of metallo-beta-lactamases (mbls) among clinically important human pathogens represents a therapeutic issue of increasing importance. however, the origin of these resistance determinants is largely unknown, although an important number of proteins belonging to the mbl superfamily have been identified in microbial genomes. in this work, we analyzed the distribution and function of genes encoding mbl-like proteins in the class rhizobiales. among 12 released complete genomes of member ...200616723554
[spatial distribution and species composition of prosthecate bacteria in lake baĭkal].from the water column of lake baikal, several strains of prosthecate bacteria belonging to the genera caulobacter and brevundimonas were isolated. in this article, the methods applied for their isolation and cell number determination are described; the occurrence frequency and spatial distribution of these microorganisms in the lake are demonstrated. characterization of the species composition of cultivable and uncultivable prosthecate bacteria was carried out using the methods of traditional an ...200717974212
expanding small-molecule functional metagenomics through parallel screening of broad-host-range cosmid environmental dna libraries in diverse proteobacteria.the small-molecule biosynthetic diversity encoded within the genomes of uncultured bacteria is an attractive target for the discovery of natural products using functional metagenomics. phenotypes commonly associated with the production of small molecules, such as antibiosis, altered pigmentation, or altered colony morphology, are easily identified from screens of arrayed metagenomic library clones. however, functional metagenomic screening methods are limited by their intrinsic dependence on a h ...201020081001
caulobacter ginsengisoli sp. nov., a novel stalked bacterium isolated from ginseng cultivating soil.a gram negative, aerobic, nonspore-forming, straight or curved rod-shaped bacterium, designated gsoil 317t, was isolated from soil of a ginseng field in pocheon province (south korea) and was characterized using a polyphasic approach. cells were dimorphic, with stalk (or prostheca) and nonmotile or nonstalked and motile, by means of a single polar flagellum. comparative analysis of 16s rrna gene sequences revealed that strain gsoil 317t was most closely related to caulobacter mirabilis lmg 24261 ...201020134228
efficacy of various chemical disinfectants on biofilms formed in spacecraft potable water system the provision of potable water is critical for successful habitation of the international space station (iss), life support systems were installed in december 2008 to recycle both humidity from the atmosphere and urine to conserve available water in the station. in-flight pre-consumption testing from the dispensing needle at the potable water dispenser (pwd) indicated that bacterial concentrations exceeded the current iss specifications of 50 colony-forming units (cfu) ml(-1). subsequent inve ...201020544435
high-resolution crystal structure of the subclass b3 metallo-beta-lactamase bjp-1: rational basis for substrate specificity and interaction with sulfonamides.metallo-β-lactamases (mbls) are important enzymatic factors in resistance to β-lactam antibiotics that show important structural and functional heterogeneity. bjp-1 is a subclass b3 mbl determinant produced by bradyrhizobium japonicum that exhibits interesting properties. bjp-1, like cau-1 of caulobacter vibrioides, overall poorly recognizes β-lactam substrates and shows an unusual substrate profile compared to other mbls. in order to understand the structural basis of these properties, the crys ...201020696874
effects of stimulation of copper bioleaching on microbial community in vineyard soil and copper mining waste.long-term copper application in vineyards and copper mining activities cause heavy metal pollution sites. such sites need remediation to protect soil and water quality. bioremediation of contaminated areas through bioleaching can help to remove copper ions from the contaminated soils. thus, the aim of this work was to evaluate the effects of different treatments for copper bioleaching in two diverse copper-contaminated soils (a 40-year-old vineyard and a copper mining waste) and to evaluate the ...201121947860
caulobacter flavus sp. nov., a stalked bacterium isolated from rhizosphere soil.a gram-stain-negative, aerobic, yellow-pigmented and rod-shaped bacterium with a single polar flagellum or a stalk, designated strain rhgg3t, was isolated from rhizosphere soil of cultivated watermelon (citrullus lanatus) collected from hefei, china. optimal growth of strain rhgg3t was observed at ph 7.0 and 28-30 °c. cells were catalase-positive and oxidase-negative. phylogenetic analysis based on 16s rrna gene sequences indicated that strain rhgg3t belonged to the genus caulobacter and showed ...201526354335
