PROCESSES FOR REDUCING LACTIC ACID IN A BIOFUEL FERMENTATION SYSTEM

The present invention relates to a process for reducing and/or preventing an increase in lactic acid levels in a fermentation product production process, such as especially ethanol production, wherein a lytic polysaccharide monooxygenase (LPMO) or an enzyme composition comprising an LPMO is added be...

Beschreibung
Zusammenfassung:	The present invention relates to a process for reducing and/or preventing an increase in lactic acid levels in a fermentation product production process, such as especially ethanol production, wherein a lytic polysaccharide monooxygenase (LPMO) or an enzyme composition comprising an LPMO is added before or during saccharification and/or fermentation, or before or during propagation, to reduce and/or prevent an increase in lactic acid levels. La présente invention concerne un procédé pour la réduction et/ou la prévention d'une augmentation des niveaux d'acide lactique dans un procédé de production de produit de fermentation, tel que notamment la production d'éthanol, comprenant l'ajout d'une monooxygénase polysaccharidique lytique (LPMO) ou d'une composition enzymatique comprenant une LPMO avant ou pendant la saccharification et/ou la fermentation, ou avant ou pendant la propagation, pour réduire et/ou empêcher une augmentation des niveaux d'acide lactique.
