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.
Claims14
A method for degradation of a pectin-rich plant biomass, comprising:
- providing a composition consisting essentially of an isolated enzyme having arabinanase activity to a pectin-rich plant biomass, and
- reacting said composition and said plant biomass at a temperature of between 35° C. and 60° C.;
- wherein said arabinanase activity comprises the activity of
- endohydrolysis of (1-5)-α-arabinofuranosidic linkages in (1-5)-α L arabinans (EC 3.2.1.99);
- wherein the enzyme has an amino acid sequence at least 99% identical to SEQ ID NO 02.
