Oil Biodegradation and Bioremediation: A Tale of the Two Worst Spills in U.S. History
Ronald M. Atlas*
University of Louisville, Louisville Kentucky 40292, United States

Terry C. Hazen
Lawrence Berkeley National Laboratory, Berkeley, California 94720, United States ABSTRACT: The devastating environmental impacts of the Exxon Valdez spill in 1989 and its media notoriety made it a frequent comparison to the BP Deepwater Horizon spill in the popular press in 2010, even though the nature of the two spills and the environments impacted were vastly di erent. Fortunately, unlike higher organisms that are adversely impacted by oil spills, microorganisms are able to consume petroleum hydrocarbons. These oil degrading indigenous microorganisms played a signi cant role in reducing the overall environmental impact of both the Exxon Valdez and BP Deepwater Horizon oil spills.

’ INTRODUCTION TO BIODEGRADATION OF PETROLEUM HYDROCARBONS Petroleum hydrocarbons in crude oils, such as those released into marine ecosystems by the Exxon Valdez and BP Deepwater Horizon spills, are natural products derived from aquatic algae laid down between 180 and 85 million years ago. Crude oils, composed mostly of diverse aliphatic and aromatic hydrocarbons, regularly escape into the environment from underground reservoirs. Because petroleum hydrocarbons occur naturally in all marine environments, there has been time for numerous diverse microorganisms to evolve the capability of utilizing hydrocarbons as sources of carbon and energy for growth. Oil-degrading microorganisms are ubiquitous, but may only be a small proportion of the prespill microbial community. There are hundreds of species of bacteria, archaea, and fungi that can degrade petroleum. Most petroleum hydrocarbons are biodegradable under aerobic conditions; though a few compounds found in crude oils,

Bp Oil Spil

...Ethics in the Workplace Case Study:   BP Oil Spill On April 20, 2010 off the Gulf of Mexico, there was a blowout of the Macondo well which is owned by British Petroleum also known as BP. When the blowout took place it got immediate media attention because aspects of the event were known over the world. Within events transpiring it was discovered how limited the resources and reaction to the disaster was going to be. This paper will detail aspects of the event from symptoms of the problem, the root cause, important unresolved issues, roles of the organization’s key players and stakeholders, and explain the focus of specific ethical systems. Also discussed in this paper are relevant strategies and alternatives, the effect of globalization on the choice of preferred alternatives, the most valid alternative and resolution recommendations, and an example of a successful implementation of the solution. Symptoms of the Problem Natural disasters or any disaster of any kind is hard to manage just for the purpose that these is no real planning for the situation and there is no real way to say who is in charge when a disaster happens. Concerning the oil spill with British Petroleum (BP) symptoms for the situation was that there was a delayed response, the impact on the environment and the citizens, federal regulations were lax, and the recovery efforts were not adequate. According to Griggs (2011), OPA 90 is a federal statute that holds all the responsible parties in containment, clean-up...

Bp Oil Spil

...The oil in a slick detected in the Gulf of Mexico last month matched oil from the Deepwater Horizon spill two years ago, the Coast Guard said Wednesday night, ending one mystery and creating another. “The exact source of the oil is unclear at this time but could be residual oil associated with the wreckage or debris left on the seabed from the Deepwater Horizon incident,” the Coast Guard said. The Coast Guard added that “the sheen is not feasible to recover and does not pose a risk to the shoreline.” One government expert said the thin sheen, just microns thick, was 3 miles by 300 yards on Wednesday. Some oil drilling experts said it was unlikely that BP’s Macondo well, which suffered a blowout on April 20, 2010, was leaking again given the extra precautions taken when it was finally sealed after spilling nearly 5 million barrels of crude into the gulf. BP declined to comment. But a BP internal slide presentation said the new oil sheen probably came from the riser, a long piece of pipe that had connected the drilling rig to the well a mile below the sea surface. The presentation said that the size and persistence of this slick, the persistent location of the oil slick origin point, and the chemistry of the samples taken from the slick ... suggest that the likely source of the slick is a leak of Macondo….oil mixed with drilling mud that had been trapped in the riser of the Deepwater Horizon rig. But Ian MacDonald, a professor of oceanography at Florida State University...

Mcdonald's Trans Fat Lawsuit

...McDonald’s for failing to reduce the amount of trans fat the company used in its cooking process. In 2002, McDonald’s had publicly announced that, by February 2003, they would voluntarily begin using an “improved cooking oil” to prepare their fried foods. Do so would significantly reduce the amount of trans fat in their products by 48% ("Mcdonald's exposed for," 2004). McDonald’s withdrew their promise and did not switch over to a cooking oil with less trans fat, nor did they reveal to consumers that the conversion did not take place. The company claims that they changed their minds when customers began complaining that they did not want the taste of McDonald’s food to change (Horovitz, 2007). BTF accused McDonald’s of false advertising, deceiving consumers, and not taking the health of their consumers into consideration. In their lawsuit, BTF claimed that “McDonald's failed to make clear to customers that the type of oil used to fry its foods (which contains TFAs) had not been changed” ("Responsible shopper," 2005). BTF did not seek monetary damages, they only asked that McDonald’s publicize their failure to switch over to the healthier cooking oil and make that conversion as soon as possible. McDonald’s claimed that it was taking longer than expected to change to a new oil, but they were working on implementing the exchange. They did not provide any information as to how long they expected this to take. The company’s Chief Operating Officer stated that, "While speedy implementation...

Types of Oil

...Organic oils Organic oils are produced in remarkable diversity by plants, animals, and other organisms through natural metabolic processes. Lipid is the scientific term for the fatty acids, steroids and similar chemicals often found in the oils produced by living things, while oil refers to an overall mixture of chemicals. Organic oils may also contain chemicals other than lipids, including proteins, waxes and alkaloids. Lipids can be classified by the way that they are made by an organism, their chemical structure and their limited solubility in water compared to oils. They have a high carbon and hydrogen content and are considerably lacking in oxygen compared to other organic compounds and minerals; they tend to be relatively nonpolar molecules, but may include both polar and nonpolar regions as in the case of phospholipids and steroids.[6] Mineral oils Crude oil, or petroleum, and its refined components, collectively termed petrochemicals, are crucial resources in the modern economy. Crude oil originates from ancient fossilized organic materials, such as zooplankton and algae, which geochemical processes convert into oil.[7] The name is a misnomer, in that minerals are not the source of the oil - ancient plants and animals are. Mineral oil is organic. However, it is classified as "mineral oil" instead of as "organic oil" because its organic origin is remote (and was unknown at the time of its discovery), and because it is obtained in the vicinity of rocks, underground...

Make Children Healthy Using Oregano Oil

...Make Children Healthy using Oregano Oil An Investigatory Project Submitted by: Aaliyah Maxine Rochelle Pangan Grade 4 St. Catherine Submitted to: Ms. Casiñas II. Rationale Your community is where you live in with your neighbors, so you got to keep it safe and healthy. By observing your community, you may get to know about it, get to know its problems and investigate the source of the problems. It is exciting to investigate because you can help your community to solve the problem. The researcher observed that children don’t like to eat vegetables that much.

Aromatherapy Research Paper

...Essential oils have a long history in the practice of aromatherapy as well as other applications from health to cleaning around the home. Having a few essential oil recipes handy for certain applications around the home and in your life can be a smart move. Not only are natural solutions to certain problems cheaper but they are also a lot healthier too which is why more and more people are drawn to them. Dual Purpose Natural Solutions The best thing about essential oil recipes is that while they may be touted for one application, they can also work wonders for something else as well. Natural air fresheners created from essential oil recipes are one example because they not only make your home smell better, but they can also end up improving your overall well-being. For instance, using a homemade air freshener with sage, lime and lavender will not only make your home smell light and airy but also calm the senses, particularly after a stressful time. Carpet deodorizers created from essential oil recipes are often mixed with baking soda to absorb the essential oils and prevent staining as many types of oils tend to do if you are not careful. Baking soda is a natural deodorizer but adding essential oils makes the carpet smell fresh and clean as well as kills certain germs causing the original odor you are trying to banish. Essential oil recipes are...

Why They Are Called: Essential Oils

...Why They Are Called, “Essential Oils” and Where They Get Their Individual Names Also known as ethereal oils, volatile oils, aetherolea, and oil of the plant, essential oils get their individual names from their source, for example, Rose essential oil is named after the Rose Bush it is extracted from, and Eucalyptus essential oil is named after the Eucalyptus tree it originates from. They call it “essential” because extracting oil captures the essence of its source and shares its scent and flavor. How Essential Oils Are Used Throughout history, many different cultures and religions have utilized essential oils for a vast array of valuable properties that they contain– physically, mentally, and spiritually. Used on its own, just one drop of an essential oil is fully loaded with an abundance of important benefits. Thus, combining these essential oils can produce powerful compelling remedies that can help with everything from skin and hair enhancement to household cleaners and room deodorizers.

Sea Buckthorn Seed Oil Research Paper

...The aroma of sea buckthorn oil is reminiscent of wet wood and just a little herbal. This oil is rarely used for its aroma, but it has many therapeutic benefits. Sea buckthorn seed oil is a very unusual essential oil in that it is almost always taken internally. This oil offers phenomenal benefits as a dietary supplement for enhancing the immune system; supporting cardiovascular, brain, and liver health; and for fighting many diseases. Sea buckthorn seed oil is rich in vitamin E and omega-3, which are only found in minute traces in the sea buckthorn berry oil. On the other hand, sea buckthorn berry oil has many topical uses and is rarely used internally.
