Pablo Iván Nikel Mayer says “How do we stop global warming and pollution of water and soil? The two most immediate actions needed are cutting the emission of greenhouse gases and limiting production of plastics from fossil resources. What if we can tackle these two problems simultaneously? Biotechnological approaches can be used to design microbes that grow on C1 substrates efficiently (an unresolved challenge in spite of decades of intense research in that area). In addition, smart microbial engineering can be deployed towards accumulation of biodegradable bioplastics. TARGET · Sustainable production of novel biopolymers by engineering efficient C1 feedstock assimilation in Pseudomonas putida combines these concepts by providing microbial cell factories that can efficiently transform formic acid (the soluble form of gaseous CO2) into novel biomaterials with applications in the packaging, biomedical, textile, agriculture and electronics industries. As such, TARGET promotes a true circular bioeconomy—both in DK and globally.”
