Bacteria elaborate iron chelators that scavenge iron from the environment, including their human and animal hosts, and iron acquisition is a determinant of pathogenicity. One such iron chelate, the siderophore ferric enterobactin, enters Gram-negative bacteria through the FepA protein of the outer membrane. The ferric enterobactin transport process is a high-affinity, multi-specific, multi-comp...

A previous investigation using the Fur titration assay system showed that Vibrio parahaemolyticus possesses a gene encoding a protein homologous to IutA, the outer-membrane receptor for ferric aerobactin in Escherichia coli. In this study, a 5.6 kb DNA region from the V. parahaemolyticus WP1 genome was cloned and two entire genes, iutA and alcD homologues, were identified which are absent from ...

backgrounds and aims: aluminum and in particular its compounds make up a large proportion of the pollutants coming from the aluminum foundry. in several studies conducted on the harmful effects of aluminum in recent decades, it has been identified as a neurotoxic metal. chronic occupational exposure through inhalation of dust is a common problem in aluminum foundries. investigation of the expos...

The focus of this study was to improve the Reverse Osmosis Cooling (ROC) process by using CaCO3 for neutralization and selective recovery Fe(OH)3 at pH 3.5. By a specific inhibitor, ferric hydroxide recovered separately from gypsum other metals present in mine water. Ferric processed pigment, product that is imported used as colorant paints tiles. In addition pigment recovery, aluminum calcium ...

Background & Aims of the Study: The wastewater created as a result of stone cutting industries enters some pools for re-consumption so that its suspended solids settle by gravity. By taking to account the high volume of water and sludge, treatment of wastewater and removal of sludge cause many problems for stone cutting units. The objective of this study was to determine the quality of wast...

The California ground squirrel (Spermophilus beecheyi) is widely distributed throughout California. It causes serious damage to agricultural crops. Tests were conducted to evaluate the fumigant aluminum phosphide (Phostoxin®) and to compare it to the commonly used gas cartridge. Treatments consisted of applying either a single-dose (two 3-gm tablets) or double-dose (four 3-gm tablets) of alumin...

background: untreated leachate is being discharged into the environment in many countries worldwide. leachate treatment methods have not been unified so far due to the variable composition of leachate. moreover, the lack of appropriate treatment and disposal of leachate causes environmental pollution. this study aimed to compare removal efficiency of chemical oxygen demand (cod) and total suspe...
