Effects of pre-exposure on the indigenous biodegradation of 14 C-phenanthrene in Antarctic soils.
The aim of this study was to investigate the biodegradation of phenanthrene in five Antarctic soils over 150 days at various temperatures and under slurry conditions. The development of catabolic activity was measured over time (1, 30, 60, 150 days) by the addition of 14C-phenanthrene and measuring...
