Duckweed biomanufacturing: longstanding promise, decade-long lag, recent renaissance.

Biomanufacturing
Those green mats carpeting your neighborhood pond could one day grow the vaccines and antibodies that stock your local pharmacy — if researchers can finally clear the hurdles keeping this surprisingly capable little plant out of the factory.
Duckweed is a tiny floating plant that doubles its mass faster than any other flowering plant and packs in nearly half its dry weight as protein. Scientists have spent 20 years using it to make drugs and vaccines in the lab, but none have made it to store shelves. This article explores why duckweed keeps getting called 'the next big thing' without ever becoming it — and whether a wave of recent advances might finally tip it over.
Key Findings
Duckweed has the fastest biomass doubling time of any flowering plant and contains up to 45% crude protein, making it a uniquely productive biomanufacturing platform.
Monoclonal antibodies and edible vaccines have been successfully expressed in duckweed at research scale for over 20 years, yet no duckweed-derived biomolecule has reached commercial production.
Duckweed can grow on wastewater and produces human-compatible sugar attachments on proteins (N-glycosylation), two advantages that most competing plant systems cannot match.

Duckweed — the tiny floating plant that blankets ponds — can produce medicines and vaccines faster and more cheaply than most crops, yet no commercial product has ever reached market. This article asks why the technology keeps stalling and whether recent breakthroughs might finally change that.

Lemnoideae is a subfamily of flowering aquatic plants, known as duckweeds, water lentils, or water lenses. They float on or just beneath the surface of still or slow-moving bodies of fresh water and wetlands. Also known as bayroot, they arose from within the arum or aroid family (Araceae), so oft...
