Scientists find way to remove polluting microplastics with bacteria

Sticky property of bacteria used to create microbe nets that can capture microplastics in water to form a recyclable blob

Microbiologists have devised a sustainable way to remove polluting microplastics from the environment – and they want to use bacteria to do the job.

Bacteria naturally tend to group together and stick to surfaces, and this creates an adhesive substance called “biofilm” – we see it every morning when brushing our teeth and getting rid of dental plaque, for example.
