To determine whether expressing the phasin PhaP improves tolerance to toxic solvents and enhances the biosynthesis of ethanol and 1,3-propanediol in recombinant Escherichia coli.
Expressed Azotobacter sp. strain FA8 phasin PhaP in wild-type and groELS mutant Escherichia coli challenged with ethanol, butanol, and 1,3-propanediol.
Quantified bacterial fitness, cell biomass accumulation, and chemical production titers in recombinant E. coli strains overexpressing phaP or the groEL chaperone.
Heterologous expression of PhaP improved bacterial fitness and survival during exposure to ethanol, butanol, and 1,3-propanediol.
Strains overexpressing phaP or groEL exhibited greater cell growth, resulting in higher final biomass and increased product titers for both ethanol and 1,3-propanediol compared to controls.
