lactis, Leuconostoc mesenteroides, L. casei, Lactobacillus rhamnosus, L. 乳,明串珠菌,属干酪,干酪乳杆菌,属 plantarum and Lactobacillus delbrueckii did not seem to possess the 植物乳杆菌和乳酸似乎并没有拥有 same aptitude to liberate encrypted bioactive peptides from caseins 资质解放加密的生物活性肽的酪蛋白 (Fuglsang et al., 北京世博翻译公司2003; Pihlanto-Leppa¨ la¨ et al., 1998). In agreement (fuglsang 等人。,北京世博翻译公司2003;pihlanto-leppa¨拉¨等人。,1998)。在协议 with data reported in literature regarding strains belonging to the 报告中的数据文献关于株的 same species (Jauhiainen et al., 北京世博翻译公司2005; Leclerc et al., 北京世博翻译公司200北京世博翻译公司2; Nakamura 同一物种(乌希艾宁等人。,北京世博翻译公司2005;勒克莱尔等人。,北京世博翻译公司200北京世博翻译公司2 村; et al., 1995), goats’ milk produced with L. helveticus PR4 alone 等人。,1995),山羊奶制作属瑞士 pr4 孤独 (FM6) showed an ACE-inhibitory activity that was the highest (fm6)显示 ACE 抑制活性,是最高的 (P < 0.01) among FMs produced with a single-starter culture. (<0.01)之间的柔性制造系统生产与 single-starter 文化。 Furthermore, by comparing the ACE-inhibitory activities of pH 4.6此外,通过比较 ACE 抑制活性的 PH 值 4.6— soluble fractions from goats’ milk fermented with a mixed-starter 可溶性组分山羊'牛奶发酵的 mixed-starter culture (FM1–3), it is noticeable that the highest ACE-inhibitory 文化(FM 1–3),值得注意的是,最高 ACE 抑制 
activity (P < 0.01) was shown by the FM1, in which one of the lactic 活动(<0.01)所表现出的简化,其中乳酸 acid bacteria used was L. helveticus PR4. In a previous study 细菌是属瑞士 pr4。在先前的研究 a partially purified proteinase from the same strain of L. helveticus 部分纯化的蛋白酶来自同一菌株属瑞士 proved capable to generate ACE-inhibitory peptides from goats’ 证明有能力产生 ACE 抑制肽的山羊 sodium caseinate (Minervini et al., 北京世博翻译公司2003). 酪蛋白酸钠(梅诺菲尼等人。,北京世博翻译公司2003)。 The highest concentration (P < 0.01) of GABA (30.86 mg kg  1) 最高浓度(<0.01)γ-氨基丁酸(30.86 毫克公斤 1) was found in FM北京世博翻译公司2 manufactured with S. thermophilus CR1北京世博翻译公司2, L. casei 被发现在 fm北京世博翻译公司2 生产嗜热链球菌 L 型,干酪 LC01 and L. plantarum 1北京世博翻译公司288 (Table 北京世博翻译公司2). Except for FM7 (1北京世博翻译公司2.84 mg lc01 和植物乳杆菌 1北京世博翻译公司288(表 北京世博翻译公司2)。除了 fm7(1北京世博翻译公司2.84 毫克 kg  1) produced with L. plantarum 1北京世博翻译公司288 alone, all the other FMs 1 公斤)产生与植物乳杆菌 1北京世博翻译公司288 孤独的,所有其他的柔性制造系统 contained GABA at lower concentrations (0.06–5.90 mg kg  1). 包含氨基丁酸在低浓度(0.06–5.90 毫克公斤 1)。 GABA is mainly synthesized by the a-decarboxylation of L-glutamic 氨基丁酸合成主要是由 a-decarboxylation 的 L -谷氨酸 acid catalyzed by the enzyme glutamate decarboxylase (GAD) 酸酶催化谷氨酸脱羧酶(总装) 
(Narayan and Nair, 1990). Several reports (Komatsuzaki et al., 北京世博翻译公司2005; (纳拉扬和头发,1990)。几份报告(komatsuzaki 等人。,北京世博翻译公司2005; Nomura et al., 1998, 1999; Park and Oh, 北京世博翻译公司2007) showed the presence 野村等人。,1998,1999;公园和哦,北京世博翻译公司2007)表明存在 of GAD in lactic acid bacteria, but the capacity to synthesize GABA 谷氨酸脱羧酶在乳酸菌,但能力合成丁酸 was different. Under our experimental conditions, only when 是不同的。根据我们的实验条件下,只有当 L. plantarum 1北京世博翻译公司288was used as a starter alone, the resulting FM7 had 植物乳杆菌 1北京世博翻译公司288was 用作起动的,由此产生了 fm7 a concentration of GABA significantly higher (P < 0.01) than all 一个显着较高浓度的氨基丁酸(<0.01)比所有 others FMs (FM4–8) manufactured with a single-starter culture 其他的柔性制造系统(fm4–8)制造的一个 single-starter 文化 (0.06–1.9北京世博翻译公司2 mg kg  1). The capacity of L. plantarum 1北京世博翻译公司288 to produce (0.06–1.9北京世博翻译公司2 毫克公斤 1)。能力的植物乳杆菌生产 1北京世博翻译公司288 GABA during milk fermentation was also higher than those previously 丁酸发酵奶也高于以前 found for other lactic acid bacteria in skim milk (Nomura 发现的其他乳酸菌在脱脂牛奶(野村证券 et al., 1998, 1999). Different strains of L. plantarum had proven 等人,1998,1999)。不同株植物乳杆菌的证明 capable to synthesize as much as 16.0 mg kg  1 of GABA during 能够合成高达 16 毫克公斤 1 丁酸在 
a 北京世博翻译公司24 h fermentation of reconstituted skim milk, even though this 北京世博翻译公司24 小时的发酵脱脂奶,虽然这 capacity was markedly strain-dependent (Siragusa et al., 北京世博翻译公司2007). In 能力明显应变(席拉哥沙等人。,北京世博翻译公司2007)。在 this study, the capacity of L. plantarum 1北京世博翻译公司288 to synthesize GABA 本研究的能力,1北京世博翻译公司288,植物乳杆菌合成丁酸 during fermentation of goats’ milk was even exalted when it was 在发酵的山羊'牛奶甚至高位时 used as a component of the mixed-starter culture comprising S. 作为一个组成部分,包括美国的 mixed-starter 文化 thermophilus CR1北京世博翻译公司2 and L. casei LC01 (manufacturing of FM北京世博翻译公司2). It may 热型和 Llc01(干酪制造 fm北京世博翻译公司2)。它可能 be hypothesized that, under our experimental conditions, a higher 推测,根据我们的实验条件下,较高的 concentration of L-glutamate, the precursor of GABA, results from 浓度的 L -谷氨酸,γ-氨基丁酸的前体,结果 metabolic activities of the two other starter lactic acid bacteria. 代谢活动的其他乳酸菌发酵。 3.北京世博翻译公司2. Characterization of the potentially functional 3.北京世博翻译公司2。表征的潜在功能 fermented goats’ milk 发酵山羊奶 A potentially functional FM using S. thermophilus CR1北京世博翻译公司2, L. casei 一个潜在的功能调频使用嗜热链球菌 L 型,干酪 
LC01, L. helveticus PR4 and L. plantarum 1北京世博翻译公司288 was manufactured lc01,属瑞士 pr4 和植物乳杆菌 1北京世博翻译公司288 制造 according to the protocol described in Section 北京世博翻译公司2. The choice of these 根据协议,在 北京世博翻译公司2 节。选择这些 lactic acid bacteria was based on the fact that FM1, obtained 乳酸菌是基于事实,简化,获得 through the use of S. thermophilus CR1北京世博翻译公司2, L. casei LC01 and L. helveticus 通过使用嗜热链球菌 L 型,lc01,属瑞士干酪 PR4, had shown the highest ACE-inhibitory activity. Since pr4,显示了最高 ACE 抑制活性。自 the use of L. plantarum 1北京世博翻译公司288 had resulted in the highest synthesis of 利用植物乳杆菌 1北京世博翻译公司288 导致最高的合成 GABA, we hypothesized that this microorganism, in combination γ-氨基丁酸,我们推测这种微生物,结合 with the three aforesaid lactic acid bacteria, could have guaranteed 与上述三个乳酸菌,能保证 for a high GABA concentration in the final product. 一个高 γ-氨基丁酸浓度在最终产品。 After incubation at 37   C until pH 4.6 was reached (ca. 3 h), cell 孵化后,在 37 摄氏直至达到 4.6(约 3 小时),细胞 counts of different starters were in the range 7.84–8.77 log cfu g  1 计数的不同首先范围在 7.84–8.77 日志祖 1 克 (Table 3). Over-acidification was observed after 45 days of storage (表 3)。over-acidification 观察后 45 天的存储 
at 4   C, the pH of the FM being 4.0. On the whole, all lactic acid 在 4,值的调频 4。总体上,所有乳酸 bacteria resulted viable after 45 days of refrigerated storage, at cell 细菌是可行的后 45 天的冷藏,在细胞 counts (Table 3) not lower than the minimum value (7.0 log cfu g  1) 计数(表 3)不低于最低值(7 日志祖克 1) recommended by the International Dairy Federation (IDF, 199北京世博翻译公司2). In 建议由国际乳品联合会(,199北京世博翻译公司2)。在 details, presumptive S. thermophilus cells remained viable at count 详细资料,推定嗜热链球菌细胞仍然可行伯爵 of 8.61 log cfu g  1. This finding agreed with a previous study that 8.61 日志祖 1 克。这一调查结果同意先前的研究 showed similar values of viable cells in fermented goats’ milk after 相似价值观活细胞在山羊'牛奶经过发酵 3 weeks of storage at 4   C (Mart?`n-Diana et al., 北京世博翻译公司2003). Overall, 3 周的存储在 4 摄氏(沃尔玛 ?`n-diana 等人。,北京世博翻译公司2003)。整体的, streptococci seemed to have higher survival than lactobacilli during 链球菌似乎有较高的生存比乳酸菌在 prolonged refrigerated conditions (Tamime et al., 1999).
