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...
The bioremediation of polluted groundwater and toxic waste sites requires that bacteria come into close physical contact with pollutants. This can be accomplished by chemotaxis. Five motile strains of bacteria that use five different pathways to degrade toluene were tested for their ability to detect and swim towards this pollutant. Three of the five strains (Pseudomonas putida F1, Ralstonia pi...
Pseudomonas has the highest number of species out of any genus of Gram-negative bacteria and is phylogenetically divided into several groups. The Pseudomonas putida phylogenetic branch includes at least 13 species of environmental and industrial interest, plant-associated bacteria, insect pathogens, and even some members that have been found in clinical specimens. In the context of the Genomic ...
Pseudomonas putida is a metabolically versatile saprophytic soil bacterium that has been certified as a biosafety host for the cloning of foreign genes. The bacterium also has considerable potential for biotechnological applications. Sequence analysis of the 6.18 Mb genome of strain KT2440 reveals diverse transport and metabolic systems. Although there is a high level of genome conservation wit...
Phenol is one of the organic pollutants in various industrial wastewaters especially petrochemical and oil refining. Biological treatment is one of the considerable choices for removing of phenol present in these wastewaters. Identification of effective microbial species is considered as one of the important priorities for production of the biomass in order to achieve desirable kinetic of biolo...
Contaminated phosphorus in aquatic environments is a critical problem. This research studied on removal of phosphorus from domestic wastewater by using Echinodorus cordifolius augmented with Pseudomonas putida and Flavobacterium oryzihabitans. Plants treated phosphorus from domestic wastewater for 20 test runs continuously, the effect of phosphorus treatment by microorganisms in domestic wastew...
The objective of this study is to investigate the efficiency of calcium carbonate bioprecipitation by Lysinibacillus sphaericus, Bacillus subtilis and Pseudomonas putida, obtained from the Coleção de Culturas do Instituto Nacional de Controle de Qualidade em Saúde (INCQS), as a first step in determining their potential to protect building materials against water uptake. Two culture media were s...
The recombinant plasmid RP4-TOL was transferred into Caulobacter crescentus at a high frequency, and the plasmid was maintained for at least 50 generations. C. crescentus cells which contained RP4-TOL grew on all the aromatic compounds that the plasmid normally allowed Pseudomonas putida to grow on. Reciprocal transfers from C. crescentus donor to P. putida or Escherichia coli recipients were l...
Aegle marmelos is a medicinal herb that has variety of biological constituents. “Catechins” are class phenolic compounds have therapeutic value. The present study employs batch extraction with methanol as solvent to extract the catechins from pulp fruit. Box–Behnken design response surface methodology (RSM-BBD) used optimize operational parameters impacting catechin extraction, such concentrati...
