determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...

Salinity stress is an important challenge for wheat production in the world. Plant growth promoting rhizosphere bacteria, isolated from halophytic plants, can increase the tolerance of crop plants to salinity by direct and indirect mechanisms. In this study, plant growth-promoting traits of bacterial strains (Bacillus safensis, Bacillus pumilus and Zhihengliuella halotolerans), isolated from th...

  Background: Urinary Tract Infection (UTI) is the second most common infection in human. Most of UTIs are due to Escherichia coli ( E.coli) and Klebsiella pneumoniae ( K.pneumoniae) . These bacteria are relevant opportunistic pathogens that account for nosocomial infections. Prevalence of Extended-Spectrum Beta-lactamase (ESBLs) in pathogenic bacteria leads to antibiotic resistance and mortali...

Although there are many health advantages assigned to different live bacteria such as probiotics, some health threatening effects have also been reported. For example, live bacteria can transfer antibiotic resistance genes to other commensal and opportunistic bacteria of gastrointestinal tract. Recently, it was shown that using killed bacteria have some advantages over live ones. In this resear...
