Effect of Microbial Polymers on the Sorption and Transport of Phenanthrene in a Low-Carbon Sand

Bacterial extracellular polymers are analyzed for their effect on the sorption, transport and mineralization of phenanthrene in porous media. Column experiments revealed a decrease in the retardation factor of phenanthrene by approximately 40% in the presence of an extracellular polymer produced by...

Zusammenfassung:	Bacterial extracellular polymers are analyzed for their effect on the sorption, transport and mineralization of phenanthrene in porous media. Column experiments revealed a decrease in the retardation factor of phenanthrene by approximately 40% in the presence of an extracellular polymer produced by a Gram-negative motile rod isolated from a coal tar waste site.
