The trials of adventive bud regeneration directly and callus induction was conducted to select out the optimal explants and formula. The results revealed that double scale can produce 13~16 adventive buds per centimeter in MS medium added 10.0 mg/L 6-BA, 1.0 mg/ L NAA, 40 g/L sugar and 7.5 g/L agar. Scale, leaves, scape and different tissue of flower can be induced to produce callus in appropriate medium, but the filament with anther was the optimized explant.

In this study, we isolate, purify and characterize endo-β-glucanase by Ascomycete Xylaria regalis. The cellulose-containing medium is used to induce the production of the cellulose-degrading enzymes. When these enzymes are produced at maximum level, we harvest and filtrate the culture medium. The filtrate is purified by anion exchanger column and hydrophobic interaction column (phenyl-650M). The purification fold of endo-β- glucanase increases 4.3 times, the specific activity approaches 3.7 unit/mg, and the recovery is 27.6%, respectively.
