A new player in the biorefineries field: Phasin PhaP enhances tolerance to solvents and boosts ethanol and 1,3-propanediol synthesis in Escherichia coli
The microbial production of biofuels and other added-value chemicals is often limited by the intrinsic toxicity of these compounds. The phasin PhaP from the soil bacterium Azotobacter sp. strain FA8 is a polyhydroxyalkanoate granuleassociated protein that protects recombinant Escherichia coli agains...

The microbial production of biofuels and other added-value chemicals is often limited by the intrinsic toxicity of these compounds.

PhaP enhances growth and poly(3-hydroxybutyrate) synthesis in polymerproducing recombinant strains and reduces the formation of inclusion bodies during overproduction of heterologous proteins. In this work, the heterologous expression of this phasin in E. coli was used as a strategy to increase tolerance to several biotechnologically relevant chemicals.
