Abstract

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.
