title: Genetic engineering of Escherichia coli for biofuel production.
abstract: In order to mitigate climate change without adversely affecting global energy supply, there is growing interest in the possibility of producing transportation fuels from renewable sources via microbial fermentation. Central to this challenge is the design of biocatalysts that can efficiently convert cheap lignocellulosic raw materials into liquid fuels. Owing to the wealth of genetic and metabolic knowledge associated with Escherichia coli, this bacterium is the most convenient starting point for engineering microbial catalysts for biofuel production. Here, we review the range of liquid fuels that can be produced in E. coli and discuss the underlying biochemistry that enables these metabolic products. The fundamental and technological challenges encountered in the development of efficient fermentation processes for biofuel production are highlighted. The example of biodiesel is a particularly illustrative case study and is therefore discussed in detail.
