Fuel-Eating Bacteria Could Be Living Under Your Gas Cap
Fuel-Eating Bacteria Could Be Living Under Your Gas Cap-July 2024
2024-02-19 EST 22:12:06

A dirty gas cap may no longer be a source of shame, but an ecosystem of friendly fuel-eating bacteria.

Scientists have discovered fuel-eating bacteria living under the gas cap of a car that could help clean up . This was found among a community of bacteria strains known to eat, or degrade, diesel fuel. And since it was found under the gas cap of a , one of the scientists it should be called “Isoptericola toyotensis.”

is just one of the authors of the paper that details the discovery, and you should go read this interview about it. Porcar and his team are from , a microbiology research firm based in Valencia, Spain.

The researchers stumbled into the fuel-eating bacteria in a parking lot, but it wasn’t really an accident. In the past, scientists have searched for bacteria able to degrade stubborn carbon sources, like diesel or gasoline, in the places they’d likely be: in sea water and sand after an oil spill. A case of following the food (or energy) source.

The idea behind these bacteria searches was that , or the removal of chemical contaminants from the ocean and soil, could benefit from the targeted use of bacteria to degrade pollution. These bugs degrade carbon sources like I degrade pizza.

But the researchers from Darwin Bioprospecting realized no one had bothered to look in places that are closer to home, and, crucially, somewhat removed from the of an oil spill.

This new discovery followed after a survey of ten cars, split evenly among five gasoline and five diesel-burning vehicles. One of these was Manuel Porcar’s beloved , and another was Juli Peretó’s .

The bacteria was — gently, I hope, for these friendly bugs — from under the gas cap of the Yaris, found within the fuel-soaked dirt that collects around the mouth of the gas tank. The researchers then bred the bacteria in the lab and “fed” it a carbon source: diesel, since gasoline is hard to use even in a controlled environment. The hungry bacteria broke down the diesel in two weeks and were thriving. Porcar says that the bacteria eating the gasoline from the Toyota Yaris hybrid suggests an adaptation, which goes to show how hearty the bugs are.

Manuel Porcar and his team are onto something here. Not just with the notable discovery in the unassuming Yaris, but also with the scientific name for the new fuel-eating bacteria. I really, really hope it inspires Toyota to make a special edition Isoptericola. That’d be one fast petri dish, rife with fuel-eating bacteria that could one day be our allies during awful oil spills. So the next time you’re angry at dirt and grime around your gas cap, think twice before wiping it.
