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.

为了分离且纯化此株菌产生在培养基中的endo-β-glucanase，先将此菌在cellulose液态培养基中大量培养，在此酵素达到最高峰时，利用滤纸过滤将菌丝及菌液分开，收集粗酵素液，再经过阴离子交换树脂及疏水性层析管柱(Phenyl-650M)等步骤予以纯化，所得到最终酵素纯度为 4.3倍，比活性为3.7 unit/mg，回收率为27.6%。

To study the expression, purification and bioactivity of human augmenter of liver regeneration in Pichia Pastoris, the expression plasmid pPICZαA- ALR was constructed and transformed into P. Pastoris by the method of electroporation transformation. Induced with 0.5% methanol, the 30 kD protein in the culture supernatant of recombinant P. Pastoris was confirmed to be rhALR by SDS-PAGE and Western blot. Quantitative analysis showed that the target protein was in a level of 66% of the total protein of the culture supernatant, with a yield of 40mg/L.we had performed DEAE anion exchange chromatography two times with excessive and regular adsorption quantity consecutively, and then the rhALR above 95% purity and 52% protein recovery could be obtained by G75 molecular sieve chromatography at last step. The bioactivity assay of the purified product showed that rhALR could stimulate the proliferation of HepG2, SMMC-7721 and NIH-3T3 in vitro.
