Description
Roderick van Roosmalen, Cormac Murphy, and Joseph Sweeney engineer bacteria that report the two mirror forms of lactic acid in grass juice. Their 2026 paper serves green biorefineries, which ferment grass silage liquid into products and need cheap, fast quality checks. The sensor strains carry genes for handling one lactic acid form each, while their own eating of rival compounds is switched off.
Building that clean background took many gene deletions, since the bacteria had to ignore sugars, other acids, alcohols, and more. One stubborn compound, succinate, required removing five separate transporter genes. Tested on Austrian and Irish silage liquids with an oxygen probe, the sensors matched a commercial enzyme kit. The approach suits small, scattered plants that cannot afford lab gear.
