DOIAbstract
Rhodococcus opacus PD630 accumulates significant amounts of triacylglycerols (TAG), but is not able to de novo synthesize wax esters (WE) from structural unrelated carbon sources, such as gluconate. In this study, strain PD630 was engineered to produce WE by heterologous expression of maqu_2220 gene, which encodes a fatty acyl-CoA reductase for the production of fatty alcohols in Marinobacter hydrocarbonoclasticus. Recombinant cells produced ca. 46% of WE and 54% of TAG (of total WE + TAG) from gluconate compared with the wild type, which produced 100% of TAG. Cell growth was not affected by the heterologous expression of MAQU_2220. Several saturated and monounsaturated WE species were produced by cells, with C18:C16, C16:C16 and C16:C18 as...
