LLNL grows methane-eating bacteria in 3D-printed hydrogel walls to make succinate

Lawrence Livermore researchers say a 3D-printed bioreactor turns methane into succinate over 10 times better than liquid systems while using less power. The account does not define the tenfold metric, and at 1 liter the reactor is still a lab device meant eventually for small landfill and wastewater sites.
