High production of polyols using crude glycerol by wild-type safe yeasts

Utilization of crude glycerol generated as a by-product from biodiesel production process, for the production of high value-added products, represents an opportunity to overcome the negative impact of low glycerol prices in the biodiesel industry. In the present investigation, alternative ways of valorization of crude glycerol have been provided, by using this renewable material as substrate by natural yeasts of the Generally Recognized As Safe (GRAS) species Yarrowia lipolytica.
