A study from Kobe University bioengineers announced the successful biosynthesis of pyridinedicarboxylic acid (PDCA), a biodegradable alternative to petroleum-based plastics such as polyethylene terephthalate (PET), using genetically engineered Escherichia coli. The engineered strain converts glucose efficiently to PDCA with high yields and minimal byproduct formation, presenting a sustainable bioproduction platform. This breakthrough represents a milestone in the development of environmentally friendly plastics and aligns with growing global efforts to reduce plastic pollution.
