Escherichia coli is a non-carotenogenic bacterium that could synthesize farnesyl pyrophosphate precursor through the isoprenoid pathway. Carotenoid production in E. coli requires heterologous expression of carotenoid synthesis genes. The carotenoid synthesis operons are assembled from genes isolated from carotenogenic bacterial
