摘要：

Copolymers of 3-hydroxybutyrate (3HB) and 3-hydroxypropionate (3HP) were synthesized in Alcaligenes latus from mixed carbon substrates of sucrose and 3-hydroxypropionic acid. The composition of copolyesters varied from 0 to 26 mol% 3HP, depending on the fraction of carbon substrates. The microbial copolyester was characterized by H-1 and C-13 nuclear magnetic resonance (n.m.r.) spectroscopy, gel permeation chromatography and differential scanning calorimetry. The copolymers were shown to have a random sequence distribution of 3HB and 3HP units by analysis of the 125 MHz C-13 n.m.r. spectra. The biosynthetic pathway of copolymers has been discussed.
