  Order Description       Explain what is oil contamination and when it happened and what are the causes. Also add why it is considered as a big problem. Also add what are the biggest oil spills happened. biodegrdation and bioremediation. Add the defenetion of both terms and why it is important to speed the degrdation of hydrocarbons in comparison to natural methods. Surfactant structure Explained what are the surfactants and what do they consist of and add pictures and make sure to site those pictures. Biosurefactant description Explain what are bisorefactant and what are there types. Also add what are the best type of BS and why? Biosurfactant properties and function Try to explain BS molleular weight, criticle micelle concentration, micelle formation, and foaming. Also add figures if possible.   Explain the role of bisorefactant in biodegrdation and bioremediation You need to explain how does the bacteria remove hydrocarbons contaminants. Try to use images and figures that will help understanding the process and make sure to cite the figure and refere to it in the text. State where this technology has been applied and what were the results and in which countries also does it have any negative impact on the environment.
