Our work has focused on the determination of physiological traits that may facilitate in situ degradation of xenobiotic compounds by indigenous microorganisms. For this our interests center on the following questions: What are the ambient conditions in a benzene, toluene, ethylbenzene, and xylene (BTEX)-contaminated aquifer? What is the behavior of indigenous bacteria under these conditions? Wh...

The present study describes the behavior of a natural phenanthrene-degrading consortium (CON), a synthetic consortium (constructed with isolated strains from CON) and an isolated strain form CON (Sphingobium sp. AM) in phenanthrene cultures to understand the interactions among the microorganisms present in the natural consortium during phenanthrene degradation as a sole carbon and energy source...

Background : Phenol and it’s derivatives were removed by physicochemical methods in the past but nowadays biological treatment has priority. Bacteria with the rapid proliferation in the presence of phenol and it’s derivatives can remove them in a good manner. The aim of this project is isolation and identification of bacteria that degrade phenol from water and sediment of Kor river and also inv...

conclusions phoma glomerata pg41 strain sharing natural substrate with toxigenic a. flavus secretes metabolites possessing a significant aflatoxin-degrading activity. the activity is associated mainly with a protein-enriched high-molecular-weight fraction of extracellular metabolites and appears to be of enzymatic origin. results the afb1-degrading activity of protein-enriched fractions, isolat...

Accurate constitutive models of the constituent materials in a reinforced concrete (RC) section, namely, unconfined concrete, confined concrete and reinforcing steel are necessary in fiber-based discretization of RC components for use in nonlinear analysis of RC structures. This paper examines the sensitivity to different constitutive models in predicting the inelastic seismic behavior of RC fr...
