| 摘要: |
| 以胆固醇为惟一碳源和能源，从食肉动物肠道的19份样中筛选出有胆固醇降解酶活性的菌株40株；通过比较，选出了在培养液中速度较快和产 酸能较强的4株菌，进而选出胆固醇降解活性较高的菌株T12－1，菌株T12－1发酵上清液应用在蛋白黄胆固醇降解中，作用显著，经动物试验，T12－1菌株在食品中应用安全、无毒。 |

| Isolation and Application of Cholesterol Degrading Strain(T12-1) from Carnivorous Animal Intestines |
|
|
|
| Abstract: |
| bacterial strains that utilized cholesterol as sole carbon and energy source were isolated from carnivorous animal intestines. A strain of Bacillus , No.T12 1 was selected for degradation of cholesterol. The action of degrading cholesterol in egg yolk was obvious and it was safety without any toxicity to apply in food processing. |
| Key words: cholesterol,Bacillus,cholesterol degrading enzymes |
