乳酸菌

Then,the test about their physiological and physiochemical characteristics and a acidophilous milk fermentation test were done for the 6 lactic acid bacterium strains.

对这6株乳酸菌进行生理生化鉴定和酸奶发酵实验。

The result showed,the acidophilous milk had a good apparent quality when the 6 lactic acid bacterium strains were used as ferment.

结果表明，6株乳酸菌作为发酵剂生产酸奶感官性能优良。

Twenty-five Wistar rats were divided into three groups: lactic acid bacteria feeding group; alcohol feeding group and control group.

5只Wistar大鼠，分为乳酸菌保护组、酒精攻击组和对照组，共服用 5天。

This paper introduces the technology of developing rich dietary fiber biscuits by using flour as the main raw material,and mixing it with highly active bamboo-shoot dietary fiber obtained through Lactobacillus bulgaricus and Streptococcus thermophilus fermentation and soluble dietary fiber.

高膳食纤维饼干是一种重要的营养保健食品。介绍了以面粉为主要原料，辅以乳酸菌发酵制备的竹笋膳食纤维和可溶性膳食纤维等成分制作高纤维饼干的工艺，并对影响饼干品质的主要因素进行了研究。

The experiment optimized the culture medium and conditions for PV 1 to yield the highest GABA: sucrose as carbon source,peptone and beef extract as complex nitrogen source,initial pH at 7.0,temperature at 30~34 ℃.The content of GABA was over 4 g/L in the optimum culture conditions.Thereby,i...

实验还对酸菜1号菌株的培养基和培养条件进行了优化：用蔗糖为碳源、蛋白胨和牛肉膏作为复合氮源、培养基初始pH为6.0、培养温度为30~34℃时该菌株发酵产GABA的量最多，发酵过程中的振荡培养(100 r/min)和静置培养对GABA的产量无明显影响；在最佳培养基组合和发酵条件下，发酵液中GABA含量可达4 g/L以上，表明利用乳酸菌进行富含GABA食品的生产是可行的。

Effects of low pH, bile salt and heat on the survival of strain L5 and L7 were studied.

研究了分离自仔猪肠道的乳酸菌L5和L7对低pH值、胆盐的耐受性。

Skimmed milk showed significantly protection against low pH and bile salt conditions,with survival counts significantly higher than the control.

体外研究表明，1％脱脂乳对乳酸菌在不同pH值和不同浓度胆盐下的存活具有显著保护作用。

Daidzein with 50 mg/L enhanced the survival counts of lactic acid bacteria under bile salt conditions, but decreased the survival counts under low pH conditions.

添加50 mg/L的大豆黄酮也明显提高乳酸菌在胆盐条件下的存活，但不能保护该菌在低pH下的存活。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
