文摘

An endo-xylanase from Aspergillus tamarii Kita was purified using CM-cellulose. The derivative glyoxyl-agarose demonstrated an important hiperactivation (2.4-fold). There was an increased thermostability of the enzyme upon multipoint immobilization. The immobilization of xylanase enabled to successfully produce xylooligosaccharides.
