Petroleum contamination in cold environments, as Arctic and Antarctic regions, represents a huge challenge since management of contaminated sites and bioremediation effectiveness in these regions depend on several factors influencing oil degradation under cold conditions facing intrinsic limiting factors. Bioremediation is considered one of the most control, marine oil spill control, biostimulation, sustainable clean-up techniques but the potential has not bioaugmentation, microbial remediation and been fully exploited in the field because it is too slow to hydrocarbon compounds. It is suggested that bioremediation should now take its place among the many techniques available for the treatment of oil spills, although there is still a clear need to set operational limits for its use.
