Process design and modeling for the production of triacylglycerols (TAGs) in Rhodococcus opacus PD630
The oleaginous microorganism Rhodococcus opacus PD630 was used to study the characteristics and kinetics of the accumulation of triacylglycerols (TAGs) in cells. In this process, accumulation of TAG is stimulated when a carbon source is present in the medium in excess and the nitrogen source is …

Investigations of lipid metabolism in Yarrowia lipolytica
… lipolytica was conducted. Yarrowia is an oleaginous ascomycete that is capable of growing on many different substrates, which derives its name from its high efficiency of growth on lipids. Once the exogenous lipids are converted into free fatty acids and internalized by the yeast, the …
