[Objective] A novel β-glucosidase encoding gene bgl17, which was functional screened from a metagenomic library constructed from the gut of Globitermes brachycerastes, was expressed in Escherichia coli BL21 and its characteristic were studied. [Methods] The recombinant enzyme Bgl17 was purified, and the stability and kinetic were identified. And the hydrolysates were analyzed by thin layer chromatography. [Results] Bgl17 was belong to glycoside hydrolase family 1(GH1), and the optimal temperature and p H of...
