摘要: 为了筛选能发酵牛乳产生较强抗高血压活性肽的乳酸菌,本研究通过发酵乳的抑制ACE活性试验,从二种干酪制品的混合样品中分离筛选出能发酵牛乳产生较强抗ACE活性的乳杆菌1002、1004和1006。经糖发酵、生长温度、精氨酸发酵产氨、产硫化氢试验及细胞壁中二氨基庚二酸(DAP)成分分析,确认它们均为瑞士乳杆菌。

Abstract: Anti- angiotensin- I-converting enzyme (ACE) were screened for obtaining the lactic acid strains which could ferment milk produce fermented milk conducting for the anti-ACE activity. 3 strains have been isolated and purified from the mixed cheese samples. These strains could ferment milk to produce anti-ACE activity significantly, and is identified as Lactobacillus helveticus.

Key words: fermented milk, angiotensin-I-converting enzyme (ACE), Lactobacillus helveticus
