Production of the sweetener erythritol by Yarrowia lipolytica strains

  • Mestrado em Biotecnologia, 2018

Abstract

Nowadays, the demand for alternatives to sugar has become a priority. Erythritol is a sugar alcohol with nearly 70 % of sucrose sweetness, with zero calories, non-cariogenic and non-glycemic. This sweetener is produced through fermentation from glucose mostly by osmophilic microorganisms. The osmotolerant yeast Yarrowia lipolytica can produce erythritol from crude glycerol, a by-product of biodiesel industry. The production of erythritol by this yeast can be affected by several parameters, such as yeast strain, medium composition and operating condition. The main objective of the present work ...
