How microbes limited the damage and helped clean up the Deepwater Horizon oil spill

How the US Department of Energy facilitated bioremediation with emulsified soybean oil

At sites where soil and groundwater were identified as contaminated with volatile organic compounds, scientists and engineers at the Office of Legacy Management used microbes to safely clean them up without more invasive methods, such as pump-and-treat. Treatment zones created at one location by injecting oil to help microbes spread quickly.

An overview of bioremediation, which can help clean up oil spills, mining waste, and some plastics

The umbrella term refers to a variety of techniques that use organisms to remove harmful substances from an environment or break them down into nontoxic compounds. Because the availability of certain resources can limit the growth of these organisms and impair bioremediation efforts, nutrients such as fertilizers can be deployed to accelerate cleanup.

Learn about unconventional ways to clean up crude oil, including using moss and chickens

Studies show that microorganisms in chicken manure can break down the hydrocarbons in crude oil without producing toxic by-products. Scientists have also explored avoiding the environmental risks of chemical dispersants and synthetic adsorbents by using human hair and peat moss to adsorb crude oil, which can be taken up by their cuticles and porous structures, respectively.

Why bacterial bioremediation may help counter the negative effects of past chemical solutions

Molecules such as DDT, a synthetic insecticide, and PFAS—"forever" chemicals used to make products resistant to heat, water, and grease—have historically been used across various industries but are now known to be harmful. Microbes that can convert some of these substances into nontoxic products, such as water and carbon dioxide, have already been identified, with ongoing research to find others.

View how cleanup crews respond to oil spills to minimize lasting damage

Oil floating on the surface can be pushed into booms with water hoses to contain the spill before being suctioned by vacuums, set on fire, or picked up by absorbent materials. In some environments, chemical cleaners can be used to disperse oil into smaller droplets that can dilute in the water, evaporate in the sunlight, or be consumed by oil-eating microbes.

Learn about historical uses of bioremediation, the oldest cleanup method on Earth

Biochemical reactions that decompose complex molecules into simpler ones have occurred on Earth for as long as life has existed and have gradually transformed the planet into a celestial body that is increasingly habitable to greater biodiversity. Along the way, modern, human-made bioremediation techniques began to take shape in Santa Maria, California, in the 1960s.

How the Supreme Court established biotechnology patent law with an oil-eating microbe

While working at General Electric, microbiologist Ananda Chakrabarty engineered a strain of Pseudomonas that could break down multiple types of hydrocarbons and filed a patent on the bioremediation organism. Despite challenges over whether living things could be patented, the 5-4 decision held that genetically modified organisms could be patented because they were human-made inventions.

Why the bioremediation of plastic and other synthetic materials is challenging

Ideonella sakaiensis, a bacterium found in recycling plant sludge in 2016, was the first organism seen to possess enzymes that could break down PET, a type of plastic. Researchers continue to search for microbes to expand bioremediation efforts to other types of plastic, but weakening the chemical bonds in many of these materials requires temperatures lethal to most microbes.

How microorganisms transformed into crude oil over millions of years

Despite the misconception that oil comes from dinosaurs, the nonrenewable resource forms when tiny organisms are subjected to high pressure and high temperature while buried under layers of sediment over tens to hundreds of millions of years. During this time, they become a mixture that is almost entirely hydrocarbons, which can be harnessed and refined.

How a polluted New York City waterway created extremophiles hungry for 'black mayonnaise'

In the 19th century, coal processing plants, oil refineries, a tannery, and other industries lining the Gowanus Canal contaminated its waters with coal tar, sewage, and other pollutants, forming the toxic sludge. Samples taken from the site before clean-up efforts revealed over 450 species of microbes with metabolisms adapted to break down these contaminants.

The 1969 Santa Barbara oil spill galvanized the modern environmental movement

In January 1969, an oil platform off the coast of Santa Barbara ruptured, releasing roughly 3 million gallons of crude into the Pacific. The spill killed over 10,000 seabirds, dolphins, and seals, coating 35 miles of coastline.

Find out how decommissioned oil rigs can be repurposed into artificial reefs

A 2014 paper analyzing drilling structures found many had become nursery habitats for fish, corals, sponges, and other invertebrates in the decades since their installation. Oil companies responsible for bringing these rigs to shore to salvage them can more affordably transport only the oil rig's deck on a barge, leaving the remaining rig to maintain the established biodiversity.

Research has shown that bioengineered algae can help remove microplastics

Scientists at the University of Missouri found that, like microplastics, some algae are particularly hydrophobic—they repel water—and that both can clump together to form a microplastic-algae sludge, which can then be collected to remove microplastics from water. Researchers believe this algae provides a scalable solution for microplastic removal that can be employed in wastewater treatment processes.

The use of fungi to detoxify land and water—a process known as mycoremediation—has been used to clean up natural resources affected by the 2025 California wildfires.

The number of annual oil spills has dropped dramatically since the 1970s

Oil spills from oil tankers—which can have a sharp, short-term impact on oil prices—have become increasingly rare over the decades in part because of stricter regulations.

What revisiting a 1979 experiment reveals about ecosystem recovery after deep-sea mining

A 2023 study co-led by the National Oceanography Centre and the Natural History Museum, London, found that tracks made by the mining vehicle remained largely unchanged since 1979. Small animals, such as amoeba-like xenophyophore, were seen in the cleared areas, but sightings of larger animals known to live in the region were much rarer. (Some readers may experience a paywall.)

Solutions of bioluminescent bacteria can create FOMO-inducing living art

A 2002 exhibition at Montana State University-Bozeman placed the bacteria onto petri dishes that served as macroscopic pixels to create images. Once the bacteria finished eating all the food in the sealed dishes, the light slowly faded away, ending the exhibit.

The history of Earth's breathable atmosphere, made possible by photosynthetic bacteria

Between 3.2 billion and 2.8 billion years ago, threadlike microorganisms called cyanobacteria began consuming available water vapor, carbon dioxide, and sunlight to produce oxygen. However, molecules released from Earth's interior by volcanoes consumed this oxygen via chemical reactions, preventing it from accumulating until volcanism had sufficiently decreased about 2.4 billion years ago.

BP only makes up about 1% of global oil production after many missteps

BP’s market cap has never recovered from the dive it took following the 2010 Deep Water Horizon oil spill. This video details some of BP’s corporate missteps along the way.

Microbial research suggests shifts in diverse populations may help an invasive species establish itself

In 1958, English ecologist Charles Elton suggested that diverse ecosystems should be more resistant to invasive species because gaining a foothold would be more challenging when resources are more thinly spread. However, in lab-grown microbial ecosystems with greater biodiversity, population volatility opened more ecological roles that invasive species could easily fill.
