Recent advances in techniques for microplastic detection, microbial biodegradation and its genomic insights: a review.
Nadekar JS, Fulke AB
Soil Health
Microplastics are now found in garden soil, tap water, and the vegetables you eat — and understanding how to detect and biodegrade them is the first step toward reversing that contamination.
Tiny plastic fragments called microplastics have spread everywhere — soil, rivers, and oceans — and scientists are racing to figure out how to find them and get rid of them. This review rounds up the best new ways to spot microplastics, from advanced microscopes to chemical sensors. It also highlights specific microbes — bacteria, fungi, and algae — that can actually eat and break down common plastics, and explains which of their genes make that possible.
Key Findings
Multiple detection technologies are now available for microplastics, ranging from traditional microscopy and infrared spectroscopy to cutting-edge hyperspectral imaging, atomic force microscopy, and electrochemical biosensors.
Specific bacterial, fungal, and algal species have been identified as capable of degrading the four most common plastics: polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), and polystyrene (PS).
Genomic research has pinpointed the specific genes, enzymes, and metabolic pathways microbes use to break down plastics, opening the door to engineered or optimized biodegradation strategies.

Scientists have reviewed the latest tools for finding microplastics in the environment and the bacteria, fungi, and algae that can break them down. This work maps out both the detection challenge and a biological path toward cleaning up plastic pollution.
Abstract Preview
The rapid increase in plastic production and use has caused a large buildup of microplastics (MPs) in land, freshwater, and ocean environments. This situation poses serious risks to ecosystems, bio...

Phytoremediation uses living plants to clean up soil, air, and water contaminated with hazardous substances. This approach is significant for plant science because it demonstrates plants' remarkable ability to absorb and metabolize pollutants, revealing key mechanisms of plant physiology and
