热激修饰瑞士乳杆菌对Cheddar干酪成熟的影响（Effects of Heat-shock Lactobacillus helveticus on Cheddar Cheese Ripening）
热激 修饰性菌株 瑞士乳杆菌
2009/11/3
研究了瑞士乳杆菌Lactobacillus helveticus6024经热激修饰后，与干酪成熟相关的生化性质变化及其对Cheddar干酪成熟的影响。结果表明：瑞士乳杆菌经70℃、10 s的热激处理后，在10%脱脂乳中经32℃、6 h培养后，其产酸能力仅为6.4%，而与干酪成熟密切相关的平均氨肽酶活力，仍有约25%的保留。热激处理后的菌株加入到干酪中对其组分没有显著影响，但对干酪可溶氮水平有不...
瑞士乳杆菌Lactobacillus helveticus ND-01是一株分离、筛选自新疆酸马奶中的乳酸菌,并且在发酵牛乳的过程中能产生较高的ACE-Ⅰ抑制活性和γ-氨基丁酸。实验通过对L.helveticus ND-01培养基的组分进行优化,从而得出L.helveticus ND-01优化培养基配方为：乳糖25 g/L,大豆蛋白胨14.1 g/L,酵母粉14.1 g/L,醋酸钠15.3 g/L...
热激法修饰瑞士乳杆菌的参数优化与特性研究（Parameters Optimization and Properties for Lactobacillus helveticus by Heat-shock Treatment）
瑞士乳杆菌 热激处理 特性
2009/9/11
采用不同热处理温度(67、70℃)与时间(10、15、20s)对瑞士乳杆菌（Lactobacillus helveticus）进行热激修饰，研究处理前后与干酪加工相关的菌体特性，同时对热激修饰条件参数进行优化。研究结果表明，菌体经70℃、10?s热激处理后，菌体存活率、动态产酸能力、蛋白水解能力等指标符合热激要求，经修饰后的菌株适宜作为干酪促熟酶源。采用扫描电镜对细菌表面微观结构的观察结果表明，热...
