a long-term study was conducted between 1985 and 2003 on rehabilitation trials at sishen ironore mine, south africa, to identify grass species that would survive in the artificial growth medium appliedto the sites, and to determine the most suitable medium for sustainable vegetation growth. vegetationestablishment was tested at slopes of 18° and 34° and with five different cover materials. afte...

a combination of an acidification reactor and an up-flow staged sludge bed (ussb) reactor wasapplied to treatment of molasses wastewater. the ussb, equipped with three gas solid separators, wasselected because of superior organic removal by means of good retention of granular sludge. the combinedsystem was continuously operated at mesophilic (35°c) conditions for 600 days. the ussb achieved a h...

in this study, oxic and anoxic microcosms were constructed with aquifer sediment collected from the vicinity of a municipal solid waste composting site.phenanthrene was used as a model pah compound. the changes of bacterial and archaeal communities in microcosms were characterized with terminal restriction fragment length polymorphism. 16s rrna gene clone library analysis was also used to inves...

background and objective: urinary tract infection (utis) is one of the most common diagnosed infectious diseases. in order to determine the spectrum of bacterial etiology and antibiotic resistance pattern of the uropathogens that cause community acquired uti, a retrospective study was performed in research center of reference laboratories of iran on urine samples of referred patients during a 4...

the objective of this study was to explore the microbial community diversities and the relationships between microbial community compositions and hydrochemical factors in nitrate contaminated groundwater of hun river alluvial plain. the method of polymerase chain reaction (pcr)-denaturing, gradient gel electrophoresis (dgge) gene fingerprints combined with canonical correspondence analysis（cca）...

Changes in the microbial community in response to catastrophic oil spills in marine and fresh water environments have been well documented. Molecular methods provide tools for analyzing the entire bacterial community, covering also those bacteria that have not been cultured in the laboratory. In this study, four different microcosms were set up containing sediments collected from the Persian Gu...
