Biosynthesis of an unusual copolyester (10 mol % 3-hydroxybutyrate and 90 mol % 3-hydroxyvalerate units) in Alcaligenes eutrophus from pentanoic acid

Abstract

Bacterial poly(3-hydroxybutyrate-co-3-hydroxyvalerate) esters with a wide range of compositions (0–90 mol % 3-hydroxyvalerate units) have been isolated from Alcaligenes eutrophus grown in nitrogen-free culture media containing pentanoic acid and glucose.
