Abstract
Disclosed is the production by fermentation of poly D-lactic acid (PDLA) and poly L-lactic acid (PLLA). In particular, there is provided engineered (prokaryotic or eukaryotic) cells for the direct synthesis of PLLA polymers and engineered eukaryotic cells for the direct synthesis of PDLA polymers starting from a carbon source, including residual biomasses of the different production chains.
