The use of chemical fertilizers has resulted in the depletion soils mineral elements and telluric microorganisms. Thus, for an improvement crop growth, exploitation microorganisms such as Pseudomonas can be alternative. Laboratory work made it possible to isolate strains from rhizospheres tomato, eggplant onion. These were also tested presence different concentrations certain metals (CuSO4 ZnSO...

In this research, effect of vermicompost and plant growth promoting rhizobacteria (PGPR) on physiological traits of lemon balm under drought stress condition was investigated in year 2012 at Karaj Research Institute of Forest and Rangelands. Experiment was conducted as split-split plot in a randomized complete block design with three replications. irrigation (normal: irrigated to field capacity...

The consumption of bottled mineral water has significantly increased in Brazil so that it is in the interest of public health to determine the parasitological and microbiological status of some brands of Brazilian mineral water available in the town of Campinas, São Paulo, Brazil. For this purpose, detection of protozoa by direct immunofluorescence technique and microbiological parameters were ...

The selective toxicity of the respiratory inhibitor Tinopal AN (1,l-bis (3,N-5dimethylbenzoxazol-2-yl) methine p-toluene sulphonate) towards phytopathogenic bacteria was investigated further and in general was confirmed using more than 160 additional strains of Pseudomonas spp. The mechanism(s) of the resistance shown by saprophytic fluorescent pseudomonads were studied to elucidate the differe...

Two seven-gene phenazine biosynthetic loci were cloned from Pseudomonas aeruginosa PAO1. The operons, designated phzA1B1C1D1E1F1G1 and phzA2B2C2D2E2F2G2, are homologous to previously studied phenazine biosynthetic operons from Pseudomonas fluorescens and Pseudomonas aureofaciens. Functional studies of phenazine-nonproducing strains of fluorescent pseudomonads indicated that each of the biosynth...

Examination of some previously isolated bile acid-utilizing Pseudomonas strains showed that Pseudomonas sp. ATCC 31752, together with other fluorescent strains, can be assigned to Pseudomonas putida biotype B, whereas Pseudomonas sp. ATCC 31753, like most other nonfluorescent strains, is an unrecognized phenotype. A study was made of the growth of these two species at 25 degrees C and pH 7.0 in...
