摘要:

对草芽孢杆菌HB-32分批发酵过程中菌体细胞生长、3-羟基丁酮的形成以及葡萄糖的消耗随发酵时间的变 化规律进行研究。基于Logistic方程和Luedeking-Piret方程,建立3-羟基丁酮分批发酵过程中细胞生长、产物合成以 及基质消耗随时间变化的数学模型。对动力学模型的拟合曲线进行分析,发现模型的计算值能与实验值较好地拟 合,拟合模型R2均大于0.98,表明建立的动力学模型能较好地反映3-羟基丁酮分批发酵过程。

Abstract:

Objective: To explore the effect of Bacillus subtilis JS01 on lipid metabolism in hyperlipidemic mice. Methods:
Ninety Kunmng mice were randomly divided into normal control group (Group Ⅰ), high-fat model group (Group Ⅱ) and highfat
+ Bacillus subtilis group (Group Ⅲ). Ten mice were selected from each group and killed on the 15th (D15), 30th (D30) and
45th (D45) days of the experiment, respectively. Triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol
(LDL-C) and high-density lipoprotein cholesterol (HDL-C) in serum and hormone-sensitive lipase (HSL) activity level in liver
were detected. Results: 1) At the three time points, serum TC, LDL-C, HDL-C and LDL-C/HDL-C ratio in Group Ⅱ were
higher than that in Group Ⅰ (P < 0.05, P < 0.01). 2) At D15 and D30, serum TG in Group Ⅱ was higher than that in Group
Ⅰ and Group Ⅲ. At D30 and D45, serum HDL-C in Group Ⅲ was higher than that in Group Ⅱ (P < 0.05). 3) At D45, liver
HSL activity in Group Ⅲ was higher than that in Group Ⅰ and Group Ⅱ (P < 0.01). Conclusion: Bacillus subtilis JS01 has
hypolipidemic effect to some extent by improving HDL-C in serum and HSL activity in liver, while reducing TG, TC and
LDL-C in serum of hyperlipidemic mice.
