Ethylene glycol metabolism in the oleaginous yeast Rhodotorula toruloides.

ABSTRACT: The agro-food chain produces an impressive amount of waste, which includes not only lignocellulosic biomass, but also plastic, used for both protective films and packaging. Thanks to advances in enzymatic hydrolysis, it is now possible to imagine an upcycling that valorizes each waste through microbial fermentation. With this goal in mind, we first explored the ability of the oleaginous red yeast Rhodotorula toruloides to catabolize ethylene glycol (EG), obtained by the hydrolysis of polyethylene terephthalate (PET), in the presence of glucose in batch bioreactor experiments. Secondly, we focused on the physiology of EG catabolism in the presence of xylose as a sole carbon source, and in a mixture of glucose and xylose. Our results show that EG is metabolized to glycolic acid (GA) in all t
