Abstract
The invention relates to the use of an isolated arabinanase enzyme comprising the activities of (1-5)-α-arabinofuranosidic linkage endohydrolysis in (1-5)-α-L-arabinans (EC 3.2.1.99), and hydrolysis of (1-5)-α-arabinofuranosidic linkages at the non-reducing end of α-L-arabinans or α-L-arabinose-oligomers (EC 3.2.1.55), particularly an arabinan-degrading enzyme isolated from Arxula adeninivorans as feed additive in livestock breeding. Furthermore, the invention relates to the application of the arabinanase in the production of fruit juices or biofuels.
Claims16
Use of an isolated enzyme having arabinanase activity for the degradation of plant biomass, in particular pectin-rich plant biomass, or for the preparation of a feed additive, wherein said arabinanase activity comprises the activities of
- a. endohydrolysis of (1-5)-α-arabinofuranosidic linkages in (1-5)-α-L-arabinans (EC 3.2.1.99), and
- b. hydrolysis of (1-5)-α-arabinofuranosidic linkages at the non-reducing end of α-L-arabinans or α-L-arabinose-oligomers (EC 3.2.1.55).
The use of an isolated enzyme having arabinanase activity for the manufacture of a single component enzyme preparation for the degradation of plant biomass, or for the preparation of a feed additive, wherein said arabinanase activity comprises the activities of
- a. endohydrolysis of (1-5)-α-arabinofuranosidic linkages in (1-5)-α-L arabinans (EC 3.2.1.99), and
- b. linkages at the non-reducing end of α-L-arabinans or α-L-arabinose-oligomers (EC 3.2.1.55).
