Some plasmid-free Tol- strains derived from Pseudomonas putida PAW1 (which carries the TOL plasmid pWW0) have a segment of TOL DNA located chromosomally. Of three independently isolated strains, PAW86 had an integrated TOL segment of 16 kilobases and PAW85 had two copies of this segment in different chromosomal locations, whereas the chromosomal DNA of PAW82 showed no homology with the TOL plas...

Strains of Pseudomonas stutzeri (CINNS) and Pseudomonas putida (CINNP and CINNW) isolated from soil with cinnamic acid as the sole carbon source were found to be simultaneously adapted to grow on phenylpropionic and p-hydroxybenzoic acids. In cinnamic acid-grown cultures, phenylpropionic acid was isolated. A catabolic plasmid of approximately equal to 75 kilobase pairs encoding the metabolism o...

Pseudomonas fluorescens strains PA4C2 and PA3G8 and Pseudomonas putida strain PA14H7 were isolated from potato rhizosphere and show an ability to inhibit the growth of Dickeya phytopathogens. Here, we report their draft genome sequences, which provide a basis for understanding the molecular mechanisms involved in antibiosis against Dickeya.

Recombinant strain Xz6-1 was constructed by the protoplast fusion technique with the goal of endowing it with the ability to efficiently degrade pentachlorophenol (PCP). This compound was considered as a representative of possible compounds that can be obtained during the bleaching of pulp for papermaking. The potential of Xz6-1 and Pseudomonas putida to treat PCP synthetic wastewater was explo...

Pseudomonas putida JS444, isolated from p-nitrophenol (PNP) contaminated waste sites, was genetically engineered to simultaneously degrade organophosphorus pesticides (OP) and PNP. A surface anchor system derived from the ice-nucleation protein (INP) from Pseudomonas syringae was used to target the organophosphorus hydrolase (OPH) onto the surface of Pseudomonas putida JS444, reducing the poten...

Analysis of chlorobenzene-degrading transconjugants of Pseudomonas putida F1 which had acquired the genes for chlorocatechol degradation (clc) from Pseudomonas sp. strain B13 revealed that the clc gene cluster was present on a 105-kb amplifiable genetic element (named the clc element). In one such transconjugant, P. putida RR22, a total of seven or eight chromosomal copies of the entire genetic...

to study the effects of different levels of seed ageing and bacteria inoculation on yield of common bean at field conditions, an experiment was carried out as factorial arranged in rcbd design with three replications at research farm of university of tehran (karaj-iran) in 2012. treatments consisted of four levels of seed ageing (0 (control), 3, 6 and 9 days at 41°c and 90-100% relative humidit...

The in vitro susceptibilities of three Pseudomonas species (Pseudomonas aeruginosa, Pseudomonas putida, and Pseudomonas fluorescens) and Xanthomonas maltophilia to quinolone antimicrobial agents were determined. Several newer agents, particularly PD117558, PD117596, PD127391, sparfloxacin (AT-4140), A-56620, and temafloxacin, were active against Pseudomonas species. X. maltophilia isolates were...

Bdellovibrio bacteriovorus HD100 is an obligate predator that invades and grows within the periplasm of Gram-negative bacteria, including mcl-polyhydroxyalkanoate (PHA) producers such as Pseudomonas putida. We investigated the impact of prey PHA content on the predator fitness and the potential advantages for preying on a PHA producer. Using a new procedure to control P. putida KT2442 cell size...

the effects of plant growth promoting rhizobacteria (pgpr) on growth and physiological characteristics of seedlings corylus avellana were determined in a forest nursery. for this purpose, in a completely randomized design (crd) and four replicates, three putative bacteria, including pseudomonas putida, bacillus subtilis and enterobacter cloacae, as alone and mixed, were examined. the greatest h...
