Enzymes involved in the manipulation of polyethylene degradation: oxidative attack by invertebrates, microorganisms and algae on microplastics.

Phytoremediation
Microplastics are now found in garden soil, compost, and the food you grow — and the promise of microbes or algae 'eating' the plastic in your backyard is still decades away from being practical.
Scientists have published thousands of studies on tiny organisms that can break down plastic, but a new analysis found most of this research is poorly documented, keeps studying the same handful of bacteria, and is done in lab conditions completely unlike real soil or water. This means we can't yet use these organisms to clean up plastic pollution in parks, farms, or oceans. The research field needs a major reset before any real cleanup tools can be built.
Key Findings
Fewer than 7% of studies reported the kinetic constants needed to assess how fast or efficiently enzymes break down plastic — making most results unreproducible.
65% of bacterial research focused on the same narrow group of species, creating a 'taxonomic echo-chamber' that ignores potentially more effective organisms.
Despite 2,931 bibliometric records analyzed, no scalable or field-ready biodegradation technology has emerged from this body of research.
chevron_right Technical Summary
A large-scale review of nearly 3,000 studies on plastic-eating organisms found that despite enormous research effort, science is far from turning microbe-based plastic breakdown into a real-world solution — largely due to poor data reporting, repetitive focus on the same few microbes, and lab conditions that don't reflect nature.

Research into polyethylene (PE) biodegradation has generated thousands of organism-level studies, yet no scalable, field-ready technology has emerged. By analysing 2931 bibliometric records alongsi...
