In the second stage, lactic-acid molecules are linked into long chains, or polymers, in chemical-reaction vessels, to produce PLA. What Dr Lee and his colleagues have succeeded in doing, as they report in Biotechnology and Bioengineering, is to produce PLA directly, in a one-stage process, in bacteria.
