Development of Bioremediation for Oil Spill Cleanup in Coastal Wetlands

摘要

Bioremediation for oil spill cleanup in the coastal wetland environment is the focus of this study. A multi-disciplinary experimental program was conducted to evaluate the use of various bioremediation products, including microbial seeding, inorganic fertilizer, and soil oxidant, as a means of enhancing oil biodegradation in coastal salt marshes. Four experiments were conducted in a controlled environment and the overall goal was to determine (1) the toxicity and ecological safety of some common biodegradation agents, (2) the effect of these bioremediation agents on crude oil degradation under the most common marsh inundation environments, (3) the effect of biostimulants on crude oil degradation as a function of soil texture, and (4) the comparative efficacy of bioremediation and phytoremediation of oil.
