Abstract: | Oil is the world’s primary source of non-renewable energy, and it has also contaminated ocean coastlines due to spills. It
is therefore important to have remediation treatments that are both effective, and ecologically not harmful. Current in situ
bioremediation methods consist primarily of biostimulation, through addition of nutrients, and bioaugmentation, the addition
of hydrocarbon degrading microorganisms. The purpose of this article is to discuss successful and unsuccessful remediation
through the use of biostimulation, bioaugmentation, or a combination of both. As microbial treatments are capable of enhancing
coastal oil remediation in temperate and tropical settings, the success of a particular remediation approach will be determined
based on the type and amount of oil, type of soil and/or sediment, microbial inoculants and the often changing physical, chemical
and biological environmental conditions. Environmental factors and limitations will be discussed as to why certain bioremediation
events were successful while others were not. |
