the iranian thymus daenensis subsp. daenensis is rich in monoterpene phenols (especially thymol and carvacrol). this research was conducted to isolate and characterize the plant growth promoting rhizobacteria (pgprs) from rhizosphere of t. daenensis. pgprs were screened based on some physiological traits including iaa production, phosphate solubilization, and siderophore compounds production ab...

Background: Aeromonas species are Gram-negative ubiquitous bacteria, facultative anaerobic rods that infect both invertebrates and vertebrates. Various fish species develop hemorrhagic disease and furunculosis due to Aeromonas spp. Aeromonas strains generate certain active compounds such as siderophores, which are the final products of non-ribosomal peptide synthetase (NRPS) activity. The prese...

Six fungal isolates were selected from the rhizosphere of black pepper (Piper nigrum L.) plants and were tested in vitro for their plant growth promoting (PGP) abilities in the soil. The species of Aspergillus selected were tested for the siderophore production, indole acetic acid (IAA) production, catalase enzyme activity and biological control of pathogens through antagonism. The results indi...

An analysis of siderophores produced by Magnaporthe grisea revealed the presence of one intracellular storage siderophore, ferricrocin, and four coprogen derivatives secreted into the medium under iron depletion. Structural analysis showed that the compounds are coprogen, coprogen B, 2-N-methylcoprogen and 2-N-methylcoprogen B. Siderophore production under low and high iron conditions was quant...

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Urinary tract infection is one of the most common bacterial infections of human. The most common agent of urinary tract infection is Escherichia coli . This study aims to determine the prevalence of uropathogenic E. coli urinary infection in human with different antimicrobial resistance, and quantitive and qualitative study of siderophore production and their association with the ability to cau...
