-Biofilm is communities of microorganisms attached to the surface and is able to concentrate metal species within their cell structure. Therefore, the aim of this study was to produce Escherichia coli biofilm on zeolite (clinoptilolite) and evaluate its ability for nickel (Ni) and chromium (Cr) adsorption from aqueous solutions. A laboratory-scale batch model was used for biodsorption assay. Th...

Objective(s): Staphylococcus aureus is an important bacterial pathogen responsible for a variety numbers of nosocomial and community acquired infections. Biofilm formation is regarded as an important factor in the establishment of S. aureus infection. The contribution of the genetic background of S. aureus to biofilm formation is poorly understood. The aim of the present work was to genotype S....

Microbial biofilm layer could grow on bed surfaces and affect the normal sediment properties following polluting of water resources. However, limited research is done to measure the effects of biofilm in the long run. The objective of this study was to investigate the erosion-deposition phenomena considering factors such as sediment concentration, flow velocity and bed surface along the flum...

The present study was focused on supply chain analysis of fresh guava in order to evaluate existing marketing supply chains (SC1: Producer - Consumer, SC2: Producer - Retailer - Consumer, SC3: Producer - Commission agent - Retailer - Consumer, SC4: Producer - Commission agent - Wholesaler - Retailer - Consumer) for two variety (allahabad safeda and apple guava) of guava. The gross marketing pri...
