제목 Production of aromatic polyester by Escherichia coli using systems metabolic engineering
초록 We engineered Escherichia coli strains by integration and overexpression of Clostridium difficile isocaprenoyl-CoA:2-hydroxyisocaproate CoA-transferase and polyhydroxyalkanoate synthase genes in a D-phenyllactate-producer strain. As a result, poly(52.3 mol% 3-hydroxybutyrate(3HB)-co-47.7 mol% D-phenyllactate) were produced from glucose and sodium 3HB. Various poly(3HB-co-D‐phenyllactate) polymers are produced by expression of Cupriavidus necator phaA and phaB genes. Fed-batch culture of this strain produces 13.9 gL-1 of poly(61.9 mol% 3HB-co-38.1 mol% D-phenyllactate). It is the first attempt for one-step fermentative production of aromatic polyesters from renewable resources.
