Abstract Endophytic bacteria have been reported to roles as biocontrol agents and plant growth promoters. The application of endophytic in the form mixed culture [consortia] will provide better effectiveness than when applied alone. This study aimed obtain a consortium that is effective biological control for purple blotch [ Alternariaporri ], promote yield shallots. research was arranged compl...

We show that the disease tomato foot and root rot caused by the pathogenic fungus Fusarium oxysporum f. sp. radicis-lycopersici can be controlled by inoculation of seeds with cells of the efficient root colonizer Pseudomonas fluorescens WCS365, indicating that strain WCS365 is a biocontrol strain. The mechanism for disease suppression most likely is induced systemic resistance. P. fluorescens s...

poor packaging and improper management causes fruits get bruised and squeezed, allowingfor different types of rots to develop when the necessary favorable growth conditions available.tomato fruit is beset with problems of both field and storage rot. throughout the presentstudy, two biocontrol bacteria pseudomonas fluorescens utpf68, and bacillus subtilis utb96the large scale production of which...

In this study we observed the proliferation of Pseudomonas fluorescens (P. fluorescens) in mouse organ homogenates at 4 degrees C. P. fluorescens secreted a protease possessing properties different from those of the mammalian tissue proteases. The specificity of this protease required a basic amino acid residue at the P1 position at a pH optimum of 6.0. The specificity of the protease was simil...

BACKGROUND Despite the proven relevance of Pseudomonas fluorescens as a spoilage microorganism in milk, fresh meats and refrigerated food products and the recognized potential of bacteriophages as sanitation agents, so far no phages specific for P. fluorescens isolates from dairy industry have been closely characterized in view of their lytic efficiency. Here we describe the isolation and chara...

Different bacterial species and, particularly Pseudomonas fluorescens, can produce gamma-aminobutyric acid (GABA) and express GABA-binding proteins. In this study, we investigated the effect of GABA on the virulence and biofilm formation activity of different strains of P. fluorescens. Exposure of a psychotropic strain of P. fluorescens (MF37) to GABA (10-5 M) increased its necrotic-like activi...

Biofertilizers containing living organisms are attractive because of their potential positive impact on plant growth and reduced environmental effect compared to mineral fertilizers. Many studies have reported the growth-promoting rhizobacteria (PGPR) cyanobacteria, applied singly or in combination. In present study, combined PGPR cyanobacteria Triticum aestivum L. was examined a hydroponic sys...

drought tolerances of 55 indigenous strains of pseudomonas fluorescens were evaluated. to assess the tolerance rate of the strains to various levels of water deficit, their growth rate in nb medium containing concentrations of 40.587, 438.838 and 548.838 g of polyethylene glycol 6000 per liter of medium were utilized. water potentials of aforesaid levels were estimated as 0, - 10, - 20 and -30 ...

to study of biological control of charcoal rot of melon caused by macrophomina phaseolina, 187 isolates of fluorescens pseudomonas isolated of rhizosphere and soil of melon plants. then 12 isolates belong to i, iii and v biovars of p. fluorescens and b biovar of p. putida were selected for greenhouse experiments based on inhibition amount. pseudomonas isolates inhibited mycelial growth signific...
