Pilot-scale production of fatty acid ethyl esters by an engineered escherichia coli strain harboring the p(Microdiesel) plasmid

Abstract

Fatty acid ethyl esters (FAEEs) were produced in this study by the use of an engineered Escherichia coli p (Microdiesel) strain. Four fed-batch pilot scale cultivations were carried out by first using glycerol as sole carbon source for biomass production before glucose and oleic acid were added as carbon sources. Cultivations yielded a cell density of up to 61 ± 3.1 g of cell dry mass (CDM) per liter and a maximal FAEE content of 25.4% ± 1.1% (wt/wt) of CDM.
