Endotoxins of Pseudomonas fluorescens
1990Heterogenous in both phenotype and genotype species, Pseudomonas fluorescens is presented by 5 biovars in Bergey’s Manual. In spite of their belonging to saprophytic organisms the strains of Pseudomonas fluorescens are frequently isolated from clinical specimens (5).

Inducible catalase in Pseudomonas fluorescens
Biochimie, 1981The catalase activity of a non-proliferating suspension of Pseudomonas fluorescens doubled after six hours incubation in a 50 mM phosphate buffer medium (pH 7.3). The same effect was observed in a peptone medium. The increased activity was due to induced enzyme synthesis, and not to activation of preexisting catalase.

Thermophilic mutants of Pseudomonas fluorescens
Archiv f�r Mikrobiologie, 1973A series of heat tolerant mutants of Pseudomonas fluorescens were obtained which can grow at temperatures up to 54°C, in contrast to a maximum growth temperature of 37°C for the wild type. The minimum temperatures allowing growth of the mutant strains increased to the same extent as their maximum temperatures.

Phospholipase C from pseudomonas fluorescens
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1971Abstract Phospholipase C found in the growth medium of Pseudomonas fluorescens was purified 2500-fold by (NH 4 ) 2 SO 4 fractionation and successive chromatography on Sephadex G-100, Sephadex G-200 and DEAE-Sephadex A-50 columns. Phosphatidyl ethanolamine rather than phosphatidyl choline was hydrolyzed extensively under our experimental conditions.

Transport of maltose by Pseudomonas fluorescens W
Archives of Microbiology, 1976The system for uptake of maltose in Pseudomonas fluorescens W was inducible. Using a mutant strain unable to hydrolyze maltose, it was shown that maltose was taken up unaltered against a concentration gradient. Uptake of 14C maltose was only significantly inhibited by nonradioactive maltose or maltotriose. These were the only sugars that could displace

The Gac regulon of Pseudomonas fluorescens SBW25.
Environmental microbiology reports, 2013Transcriptome analysis of Pseudomonas fluorescens SBW25 showed that 702 genes were differentially regulated in a gacS::Tn5 mutant, with 300 and 402 genes up- and downregulated respectively. Similar to the Gac regulon of other Pseudomonas species, genes involved in motility, biofilm formation, siderophore biosynthesis and oxidative stress were ...

Adhesion of Pseudomonas fluorescens on magnetic surfaces
Colloids and Surfaces B: Biointerfaces, 2004The adhesion of Pseudomonas fluorescens (ATCC 700830) to perpendicularly polarized magnetic surfaces was recently discovered. The findings have found that the magnetic free surfaces from different magnetic polarities have different profound effects on the P. fluorescens bacterial adhesion to its surfaces. These phenomena can be explained by the surface

In sterile vermiculite P. fluorescens 2137gus colonized 80???90% of barley roots surface. The essential fluctuation of colonization intensity of the roots by 2137gus was established. In F. culmorum presence the intensity of root colonization by 2137gus could be decreased. It is evidence that F. culmorum can influence P.

Cesium Stress and Adaptation in Pseudomonas fluorescens
Bulletin of Environmental Contamination and Toxicology, 1996Industrialization and acid rain have led to a marked increment on the bioavailability of numerous metals. These metallic pollutants pose a serious threat to the ecosystem due to their ability to interact negatively with living organisms. Thus, considerable effort has been directed towards the development of environmentally-friendly technologies ...

Styrene Catabolism by a Strain of Pseudomonas fluorescens
Systematic and Applied Microbiology, 1983A strain of Pseudomonas fluorescens, capable of growing on styrene as the sole C source was isolated from enrichment cultures. From the Pseudomonas cultures supplied with styrene, phenylacetic and o-hydroxyphenylacetic acids were isolated and identified, o-Hydroxyphenylacetic acid was also isolated from the cultures supplied with phenylacetate ...
