Is Crude Oil Bioremediation Affected by Changes in Ambient Ultraviolet Radiation?

摘要

Biodegradation of Iranian light crude oil using an oleophilic fertilizer (F1) was investigated in two 30-day runs in a mesocosm simulation of a typical Mediterranean shore in the winter and spring periods of 1996 and 1997. At the end of the 30-day periods alkane biodegradation was dramatic (70%) and statistically significant only in the first run (November-December). Given that the fluctuations in all other parameters were minimal, the notable reduction in biodegradation efficiency during the second run is thought to be related to the nearly three-fold increase in total dose of solar UV-B radiation.
