n ‐Amyl alcohol was examined as a source for the synthesis of the 3‐hydroxyvalerate (3HV) unit of the biopolyester, poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (P(3HB‐co‐3HV)), by Alcaligenes sp., Pseudomonas sp. and several methylotrophic bacteria. A. eutrophus and Ps. lemoignei synthesized P(3HB‐co‐3HV) from glucose and n ‐amyl alcohol under nitrogen‐deficient conditions. Many of methylotrophic bacteria grown on methanol synthesized the copolyester from methanol and n ‐amyl alcohol under nitrogen‐deficient conditions. The content and composition of the polyester varied from strain to strain. Paracoccus denitrificans differed from all others in having a higher content of 3‐hydroxyvalerate units in the copolyester synthesized.
