Carrot Discard as a Promising Feedstock to Produce 2,3-Butanediol by Fermentation with DSM 365.

The valorization of fruit and vegetable residues (such as carrot discard) and their microbial conversion into 2,3-butanediol (BDO) can be considered as a very interesting way to reduce food waste and sustainably originate high value-added products. This work analyzes the valorization of carrot discard as feedstock for 2,3-butanediol (BDO) production by DSM 365. The influences of stirring and the presence of tryptone (nitrogen source) are studied.
