Construction of an Antibiotic-Free Vector and its Application in the Metabolic Engineering of Escherichia Coli for Polyhydroxybutyrate Production

Frontiers in Bioengineering and Biotechnology, 2022
An antibiotic- and inducer-free culture condition was proposed for polyhydroxybutyrate (PHB) production in recombinant Escherichia coli. First, antibiotic-free vectors were constructed by installing the plasmid maintenance system, alp7, hok/sok, and the ...

Production of polyhydroxybutyrate in sugarcane

Plant Biotechnology Journal, 2006
SummaryWe report here the production of the bacterial polyester, polyhydroxybutyrate (PHB), in the crop species sugarcane (Saccharum spp. hybrids). The PHB biosynthesis enzymes of Ralstonia eutropha [β‐ketothiolase (PHAA), acetoacetyl‐reductase (PHAB) and PHB synthase (PHAC)] were expressed in the cytosol or targeted to mitochondria or plastids.
