Characterization of bacterial communities in lithobionts and soil niches from Victoria Valley, Antarctica.

abstract：:Terrestrial sites contaminated with 2,4,6-trinitrotoluene (TNT) are a widespread and persistent problem and often contain non-vegetated areas with TNT concentrations well in excess of 1000 mg kg(-1). In this study, we examined the effect of TNT on denitrification activity in field soils, and compared the sensitivity o...
