Polylactic acid, also known as polylactide, has attracted attention as an alternative material to petroleum-based plastics, but the material is brittle and difficult to mold and dissolve. A type of polylactide with enhanced degradability, known as LAHB, has already been developed, but it is difficult to produce in bulk. To address such shortcomings, the team utilized a bacteria known as lactate dehydrogenase capable of producing plastic, and through its genetic modification, the team managed to mass-produce LAHB. LAHB by itself is cloudy white in color, but the team achieved a typical transparent appearance by adding a small amount of LAHB to conventional polylactic acid. The Japanese government hopes to increase the country's use of bioplastics to approximately 2 million tons by 2030.
