4-Hydroxybutyrate-3-hydroxypropionate-lactate terpolymer was prepared according to the method of example 2 except that the collected cells was anaerobically cultured for 3 days in MR medium further containing 2 g/L of 4-hydroxybutyrate (4-HB), 2 g/L of 3-hydroxypropionate (3-HP), 100 mg/L of ampicillin and 30 mg/L of chloramphenicol instead of MR medium further containing g/L of 4-HB, 100 mg/L of ampicillin and 30 mg/L of chloramphenicol. —As a result of the analysis, methyl-4-hydroxybutyrate, methyl-3-hydroxypropionate and methyl-lactate were detected in E. coli Top10/pPs619C1300-CPPCT/pMCSPtbBuk transformant, which meant that new 4-hydroxybutyrate-3-hydroxypropionate-lactate terpolymer [poly(4-hydroxybutyrate-co-3-hydroxypropionate-co-lactate)] was prepared by the recombinant E. Coli. 1H-NMR and GC-MSD results of the obtained 4-hydroxybutyrate-3-hydroxypropionate-lactate terpolymer were shown in FIGS. 6 and 7, respectively.
