Technosols are modified soils affected by human activities. This study investigated genesis, classification and physicochemical properties of four pedons of Technosols developed on refused oil refinery materials and compared them with two unpolluted pedons. Mineralogical studies showed smectite as a dominant clay mineral with other clay minerals. These clay minerals adsorb oil compounds in thei...
The effect of bacterial quorum sensing (QS) signals on the respiration activity of an oil-polluted soil with and without the addition of an alkane-degrading bacterial consortium was investigated. The addition of C4eC12-HSL N-acyl homoserine lactones (AHLs) to the contaminated soil with the bacterial consortium resulted in a significant increase in CO2 evolution rates. Experiments with 1, 10 and...
Surface soils from Guiyu, China (an intense e-waste processing center) were analyzed for persistent organic pollutants (POPs) and variations in composition of the resident bacterial communities. Denaturing Gradient Gel Electrophoresis analysis of bacterial 16S rRNA gene showed that e-waste pollution altered the bacterial community structure by promoting changes in species composition and specie...
