Application of the yeast Yarrowia lipolytica for food additives production

Abstract

[Excerpt] Introduction: Yarrowia lipolytica is a nonconventional, aerobic and dimorphic yeast with many biotechnological applications due to the wide range of substrates that can use as carbon source and the ability to produce a large variety of metabolites with industrial interest. It can usually be found in environments containing hydrophobic substrates, such as alkanes and fats. It can also be isolated from cheeses, yoghurts, kefir, soy sauce, meat and shrimp salads. Y. lipolytica has been proved to be a robust cell for the biotechnological production of compounds that can be used as additives in food industry, such as organic acids (citric acid), enzymes (such as proteases and lipases), biosurfactants, sweeteners (such as erythritol and mannitol), and aroma and fragrances compounds.
