ABSTRACT

Despite many studies, the “check points” of metabolic regulation of citric acid (CA) secretion by the yeasts Y.lipolytica still remain unknown. In this manuscript, some possible aspects of strain dependent secretion as well as CA metabolism regulation were discussed. Keys enzymes’ activities, substrate concentration, affinity of the uptake systems, intracellular CA concentration and strains abilities were the main points taken into consideration. The direction for the future studies emerged from this review, mainly connected to cellular and mitochondrial citrate transport systems and cellular substrates transporters (glucose, fructose, glycerol, ethanol and acetate), give promising starting point for future efficient strain development.

Key words: Yarrowia lipolytica, citrate synthase, intracellular CA, glucose consumption, RAPD.
