An Australian team from James Cook University has identified a type of red alga, Asparagopsis taxiformis, which reduced methane production by 99% when tested on artificial cow stomachs in laboratory conditions. This species of seaweed is effective because it produces a compound called bromoform (CHBr3) that reacts with vitamin B12 in ruminant stomachs to block methane production. Trials are ongoing in Queensland.
