摘要

β-葡萄糖苷酶可将大豆异黄酮苷转化为苷元，在大豆培养基中培养时，枯草芽孢杆菌Miyagino菌株的活性明显低于枯草芽孢杆菌168菌株。在枯草芽孢杆菌Miyagino菌株中发现了β-葡萄糖苷酶相关基因bglH的失活。本研究表明，bglH表达降低显著影响枯草芽孢杆菌Miyagino菌株β-葡萄糖苷酶活性降低。

Inactivation of bglH, a key β-glucosidase gene involved in isoflavone aglycone production, in Bacillus subtilis strain Miyagino.

β-Glucosidase converts soybean isoflavone glucosides to aglycones, and Bacillus subtilis strain Miyagino shows remarkedly lower activity than B. subtilis strain 168, when cultured in soybean-based medium. The inactivation of bglH, a key β-glucosidase-related gene, was found in B. subtilis strain Miyagino. This study indicates that the decreased bglH expression significantly affects the low β-glucosidase activity of B. subtilis strain Miyagino.
