Abstract

A biosynthetic pathway for poly(3-hydroxybutyrate) [P(3HB)] was developed in Escherichia coli and Corynebacterium glutamicum by an acetoacetyl-coenzyme A (CoA) synthase (AACS) recently isolated from terpenoid-producing Streptomyces sp. strain CL190. Expression of AACS led to significant productions of P(3HB) in E. coli (10.5 wt %) and C. glutamicum (19.7 wt %).
