¹³C metabolic flux analysis-guided metabolic engineering of Escherichia coli for improved acetol production from glycerol.

ABSTRACT:

Background

Bioprocessing offers a sustainable and green approach to manufacture various chemicals and materials. Development of bioprocesses requires transforming common producer strains to cell factories. ¹³C metabolic flux analysis (¹³C-MFA) can be applied to identify relevant targets to accomplish the desired phenotype, which has become one of the major tools to support systems metabolic engineering. In this research, we applied ¹³C-MFA to identify bottlenecks in the bioconversion of glycerol into acetol by Escherichia coli. Valorization of glycerol, the main by-product of biodiesel, has contributed to the viability of biofuel economy.

Results

We performed ¹³C-MFA and measured intracellular pyridine nucleotide pools in a
