researchers of csiro land and water in griffith in australia have found a way to repeatedly reuse drainage water to grow crops. in the process the system will concentrate the salt in the water to a manageable level which can then be used or stored in an environmentally friendly manner. the process, known as sequential biological concentration, is based on a novel system for land, based treatmen...

results the results revealed the formation of spherical silver nanoparticles with an average size of 10 nm. moreover, concentration of snps in a 25 ml sample containing both snps and plant extract biomass was 2.934 mg/l on average. serial microdilution test showed that snps at the concentration of 50 μg/ml can inhibit growth of the pathogen. conclusions the present study extends the existing li...

background: the presence of chemical compounds has different effects on the rate of degradation of materials and on changing dominant microorganisms in the biological degradation processes. these effects are related to the type and concentration of compounds. this study was to evaluate the effect of different concentrations of glucose as a growth substrate on phenol removal efficiency and micro...

BACKGROUND The objectives of this study were to determine whether a single result for total prostate-specific antigen (tPSA) can be used confidently to guide the need for prostate biopsy and by how much serial tPSA measurements must differ to be significant. tPSA measurements include both analytical and biological components of variation. The European Group on Tumor Markers conducted a literatu...

background: the effect of curcumin as a natural safe compound with different biological activities was examined on fungal growth and aflatoxin production in aspergillus parasiticus nrrl 2999. methods: the fungus was cultured in presence of serial two-fold concentrations of curcumin (125-2000 µg/ml) in yeast extract sucrose broth for 3 days at 28°c. mycelia dry weight was determined as an index ...

this laboratory study simultaneously was conducted to evaluate the resistance to heavy metals, silver, cadmium and a number of commonly used antibiotics. sampling was done in 2014 of the two silver workshops in isfahan, and the inlet of phase 2 of shahin shahr wastewater treatment plant, isfahan. to isolate resistant bacteria to metal silver and cadmium and review multiple resistance to other m...
