Production levels are currently low, but researchers hope the method could one day mean pharma doesn’t have to rely on animals for this essential medicine

Scientists in China have genetically engineered yeast to turn methanol into heparin. The work is a step towards a sustainable production process for the essential anticoagulant that could mean drug makers no longer need to source it from animals.
