Introduction

Lactic acid monomer polymer (PLA), which is completely biodegradable in the natural environment, is an idealreplacement of plastics. To address the lack of new strains and the gap in fermentation production technology, thistechnology breeds a high-yield new strain of lactic acid monomer with complete independent intellectual propertyrights, and develops a new technology suitable for large-scale production using starch, glucose and sucrose as rawmaterials. The product meets the processing reguirements of degradable polylactic acid materials, with controllable costand world-leading production efficiency.
