Properties of Three Plasmids Isolated From Plant Pathogenic Pseudomonads
Indigenous plasmids isolated from Pseudomonas tabaci ATCC 11528 (pJP1), P. tabaci BR2 (pBPW1), and P. angulata 45 (pJP30) were labeled with Tn3 using RSF1010::Tn3 as a vector and the host strains were subsequently cured of their Tn3-containing plasmid. Plasmid-containing and respective cured …

Molecular and Genetic Relationships of Aromatic Metabolic Plasmids in Pseudomonads
This thesis elucidates the similarities among the pseudomonad metabolic plasmids required for growth on the substrates naphthalene, NAH, salicylate, SAL, xylene and toluene, XYL and TOL. Naphthalene and xylene dissimilation pass through salicylate and toluate as intermediates to converge at …

Role of translesion DNA polymerases in mutagenesis and DNA damage tolerance in Pseudomonads
Kahjustused DNA-s, mis tekivad kas rakkude normaalse elutegevuse käigus või erinevate keskonnategurite mõjul (näiteks UV-kiirgus, DNA-d kahjustavad kemikaalid), pärsivad genoomi replikatsiooni, takistades replikatiivse DNA polümeraasi edasiliikumist. Pikaajaline replikatsiooni seiskumine võib …

Screening environmental Pseudomonads for characteristics suitable for a bio-engineered oil remediation agent
… related group of bacteria.<br/> A total of 355 pseudomonads and Pseudomonas-like isolates were isolated from activated sludge wastewater and potentially petroleum-contaminated soils from road side drainage (SUDS) site. These were phenotypically characterized using a number of growth and …

Phenotypic and genetic diversity of pseudomonads associated with the roots of field-grown canola
Pseudomonads, particularly the fluorescent pseudomonads, are common rhizosphere bacteria accounting for a significant portion of the culturable rhizosphere bacteria. The presence and diversity of Pseudomonas spp. in the rhizosphere is important because of their ability to influence plant and soil …

The 16S rRNA characterization of a novel "microaerophilic" Pseudomonas sp. from the oligotrophic deep subsurface environment
… strain, indicating a similarity to the (Group I) pseudomonads. DNA-DNA reassociation was performed between <i>Pseudomonas</i> sp. strain MR 100 and 11 representative p seudomonads using the S 1 nuclease method. Strain MR 100 was found to be 20% homologous to the <i>Pseudomonas mendocina</i> type …

Assessing the role of probiotics for the enhancement of soil quality under cover crops
… on King's B medium selective for fluorescent pseudomonads. Fluorescent pseudomonads were significantly higher in Trt3 than control after the second probiotic application. Auxin production in soil samples was determined by high-performance liquid chromatography-Mass spectrometry (HPLC-MS/MS). …

Responses of an Environmental Gram-negative Bacterium to Pollutant Stress
Several strains of pseudomonads which are normally found in natural water and soil environments, including Pseudomonas fluorescens, Pseudomonas aeruginosa, and strains initially identified as Pseudomonas paucimobilis and Pseudomonas maltophilia, were used in this thesis and their stress responsive …

A comparison of the bacteria at Bakoven Bay and Hottentotshuisie as indicators of marine pollution from a sewage outfall
… Total count isolates and in particular the pseudomonads also showed bacteriological differences between the sites. It is indicated that these organisms could possibly be used to demonstrate stressed conditions in near-shore marine environments resulting from sources other than sewage …

Detection of the fluorescing group of Pseudomonas by enzyme-linked immunosorbent assay (ELISA) for the prediction of shelf-life of dairy products
… incubation to determine the number of pseudomonads present and the relationship between ELISA and plate counts. These numbers were correlated to the shelf-life of each sample, as determined by sensory evaluation. Samples undergoing a preliminary incubation with only milk gave the best …

A mycological survey of commercial whirlpools in Delaware and Madison counties, Indiana
… 43% of all samples, and blue-green fluorescent pseudomonads were found in 54% of all samples. Most dermatophytes were isolated from the step access surface of the facilities tested, and more Candida species were isolated from the water than from either surface tested.

Characterization of diazotrophs containing Mo-independent nitrogenases from diverse natural environments
… appear to be closely related to the fluorescent pseudomonads. The presence of Mo-independent nitrogenases in all isolates was detected using PCR and/ or Southern Blot hybridization. Of particular interest are isolates, AN1, BJM and LPF4 that are closely related to Citrobacter sp., Klebsiella sp. …

Comparative biochemistry and genetic analysis of nucleoside hydrolase in Escherichia coli, Pseudomonas aeruginosa, and Pseudomonas fluorescens.
… hydrolases. The nucleoside hydrolases of the pseudomonads exhibited markedly different modes of regulation. Both have unique promoter structures and genetic organization. Furthermore, both pseudomonad nucleoside hydrolase were found to contain an N-terminal extension of 30-35 amino acids that …

Assessment and Characterization of Microbial Communities in Salt Affected Soils on Galveston Island
… 4.07 to 5.12 log CFU/gram and from 3.73 to 4.26, pseudomonads from 4.09 to 5.21 and from 3.76 to 4.28, actinomycetes from 4.14 to 5.22 and from 3.87 to 4.32, and fungi from 3.27 to 3.58 and from 3.09 to 3.71 in summer then fall, respectively. There were no consistent statistical differences in …

Polynomials and models of type theory
… make sense in a category when there exist pseudomonads freely adding indexed sums and products to fibrations over the category, and a category of polynomials is obtained by adding sums to the opposite of the codomain fibration. A fibration with sums and products is essentially the structure …

Adaptation and niche construction by Pseudomonas fluorescens SBW25
… populations in static microcosms.<br/><br/>Other pseudomonads had previously been shown to produce cellulose-based A-L interface biofilms in static microcosms. Here, a survey of New Zealand brown blotch-causing pseudomonads (BCP) recovered from white mushrooms (<i>Agaricus bisporus</i>) identified …

Metabolism, nutritional effects, and mutagenesis of crystal violet decolorization by a biofungicide agent Pseudomonas putida strain M-17
… to selectively recover genetically engineered pseudomonads from environmental samples. One isolate (M-17) was found to produce a red halo around single colonies grown on media containing 10 mg/l crystal violet. This decolorization reaction was constitutively produced when the growth medium …
