For years, the response to major offshore oil spills has proven not adequate enough because oil often spreads rapidly to enormous areas and is deposited over broad coastal regions. Even when containment and spill response systems can be mobilized in time, they are usually insufficient to deal with the very large volumes of the spilled oil.
After oil spills by allowing natural weathering to degrade the oil as a possible choice under certain situations. Researchers had frequently documented that the adding of the nutrients in the form of fertilizer to native microorganisms has demonstrated to be effective in improving the biodegradation and is environmentally safe at the same time.
It has furthermore has been observed, that microbes with the ability to degrade oil are existing in almost all coastal environments and that the environmental parameters besides nutrients will disturb the actual degradation rates. Thus the applications of the nutrients are still to some degree affected by temperature, water runoff, substrate, and other environmental limitations that are neither completely understood nor easily measured.
Nevertheless, there still remains a part for the bioremediation in marine oil spills cleanup since knowledge has revealed that no solo method will ever be suitable for all the occurrences demanding response after the oil spills.
Lastly, there are several advantages to be gained from a fast cleanup of an oil spill, some of which do not relate to the marine ecosystem, but to other worries. These consist of economic influences from the loss of shorelines for recreation, legal liabilities and settlement of claims, and aesthetic considerations.
