Application

EC Number Application Comment Organism
3.2.1.177 synthesis utility of enzyme AxlA from Aspergillus niger in supplementation of CTec2/HTec2 from Trichoderma reesei for enhancing release of free Glc and Xyl in combination with commercial enzyme cocktails from dicotyledonous and monocotyledonous plants, overview. AxlA supplementation also improves Glc yields from corn stover treated with the commercial cellulase Accellerase 1000 Aspergillus niger
