Detailed overview of innovation with sample startups and prominent university research
What it is
Precision fermentation utilizes microorganisms, such as bacteria, yeast, or fungi, as tiny factories to produce specific proteins. This process involves genetically engineering these microbes to express target proteins that are identical to those found in animals or plants. Instead of raising animals or cultivating vast fields of crops, precision fermentation harnesses the power of biology to create proteins in a controlled and efficient manner.
Impact on climate action
Precision Fermentation revolutionizes livestock farming by creating lab-grown animal feed, slashing methane emissions. This innovation minimizes reliance on traditional feed production, reducing deforestation and methane output from livestock digestion. It marks a significant step towards sustainable agriculture, mitigating climate change’s impact and fostering a greener future.
