Abstract
Provided is a method of preparing polylactate (PLA) or a copolymer thereof using a mutant microorganism in which a gene participating in a coenzyme A (CoA) donor- and lactate-producing pathway is genetically manipulated to increase the productivity of a CoA donor and lactate. Amounts of the CoA donor and the lactate are simultaneously increased in a microbial metabolic pathway to enable effective biosynthesis of PLA and a hydroxyalkanoate-lactate copolymer having a high content of lactate, which is industrially useful.
