| 摘 要： | 筛选到一株泡木贼镰刀菌(Fusarium equiseti)90-9菌株,它能转化石胆酸(Lithocholic acid)为熊去氧胆酸(Ursodeoxycholic acid).该菌转化0.1%(W/V)石胆酸96h,熊去氧胆酸重量收率为38.1%.经各项理化性质,包括熔点、比旋值、红外光谱、核磁共振谱、质谱和元素分析等项鉴定,证明产物为熊去氧胆酸.

| Abstract: | Fusarium equiseti 90-9 was screened for microbial production ofursodeoxycholic acid from lithocholic acid. The weight yield was 38.1% in the presenceof 0.1% lithocholic acid (W/V) within 96h of cultivation. Determination of severalphysical-chemical characteristics including melting point, specific rotation, infraredabsorption spectrum, nuclear magnetic resonance, mass spectrum and elementcomposition etc indicated that the main product was ursodeoxycholic acid. |
