Beneath the ocean’s surface, bacteria have evolved specialized enzymes that can digest PET plastic, the material used in bottles and clothes. Researchers at KAUST discovered that a unique molecular signature distinguishes enzymes capable of efficiently breaking down plastic. Found in nearly 80% of ocean samples, these PETase variants show nature’s growing adaptation to human pollution.
The bacteria release carbon during the decomposition process. So this isn’t a “solution” in any meaningful respect. It’s an instance of evolution at work, as a surplus resource becomes a food source for innovative organisms.
Also, we look at this as some kind of “clean-up”. In reality, this is a threat to one of our most useful durable materials. It’ll likely lead to the development of antiseptics to kill these bacteria colonies, as the last thing anyone with a hard plastic shell on their vehicle or appliance or equipment wants is a colony of plastic-eaters deteriorating it.
