海洋拟诺卡氏菌株HY-G及其产生的β-葡萄糖苷酶
摘要：
本发明是一种海洋拟诺卡氏菌株HY-G(Nocardiopsis sp.HY-G)CCTCCNO：M 2010126。本发明还公开了海洋拟诺卡氏菌株HY-G CCTCC NO：M2010126产β-葡萄糖苷酶的方法及产品；所产的β-葡萄糖苷酶属于胞内酶，其分子量为43～45kDa；该酶在以p-NPG为底物时，测得在pH 6.0-9.0有酶活力，其中在pH 7.0-8.0时酶活力强；该酶在40-60℃下具有有酶活性；Fe2+、Mg2+、pb2+、Na+、Fe3+对该酶活性有促进作用，其中Fe2+、Fe3+促进作用强，Ca2+、Zn2+、Ag+、Cu2+、K+对该酶活性有抑制作用，其中Zn2+、Ag+、Cu2+抑制作用强。
摘要（英）：

The invention relates to a marine nocardiopsissp.HY-G CCTCC NO: M 2010126. The invention also discloses a method for producing beta-glucosidase with the marine nocardiopsissp.HY-G CCTCC NO: M 2010126 and a product. The produced beta-glucosidase belongs to entoenzyme with a molecular weight of 43-45 kDa. When the beta-glucosidase uses p-NPG (Neopentyl Glycol) as a substrate and is measured to haveenzyme activity in case of a pH value of 6.0-9.0, the beta-glucosidase has the strongest activity in case of a pH value of 7.0-8.0 and has enzyme activity at 40-60 DEG C; the enzyme activity is stimulated by Fe2+, Mg2+, pb2+, Na+ and Fe3+, wherein the Fe2+ and the Fe3+ have strong acceleration; and the enzyme activity is inhibited by Ca2+, Zn2+, Ag+, Cu2+ and K+, wherein the Zn2+, Ag+ and Cu2+ have strong inhibition.
