进一步的,按植物乳杆菌菌液的重量百分比计,包括如下成分:
脱脂乳粉 10-12份;
乳糖 8-10份;
甘油 2.5-3.5份。
进一步的,按植物乳杆菌菌液的重量百分比计,包括如下成分:
脱脂乳粉 11.37份;
乳糖 8.27份;
甘油 3.06份。
进一步的,将植物乳杆菌菌液与复合冻干保护剂液体按1:2比例进行冷冻干燥,冻干存活率达到71.88%。
本发明的有益技术效果:按照本发明的植物乳杆菌复合冻干保护剂,本发明提供的植物乳杆菌复合冻干保护剂,既可以优化配方,又可以发现保护剂彼此间作用关系,大幅度提高菌种冻干存活率。
附图说明
图1为按照本发明的植物乳杆菌复合冻干保护剂优化方法的一优选实施例的流程图。
具体实施方式
为使本领域技术人员更加清楚和明确本发明的技术方案,下面结合实施例及附图对本发明作进一步详细的描述,但本发明的实施方式不限于此。
实施例1:
本实施例1提供的一种植物乳杆菌复合冻干保护剂,按植物乳杆菌菌液的重量百分比计,包括如下成分:
脱脂乳粉 11.37份;
乳糖 8.27份;
甘油 3.06份。
进一步的,将植物乳杆菌菌液与复合冻干保护剂液体按1:2比例进行冷冻干燥,冻干存活率达到71.88%;比不使用该复合冻干保护剂可以提高70.03%,与其他比例体积比相比提高30%左右。
如图1所示,本实施例1提供的一种植物乳杆菌复合冻干保护剂优化方法,包括如下步骤:
步骤1:从脱脂乳粉,乳糖,半乳糖,蔗糖,海藻糖,甘露醇,侧金盏花醇,甘油,脯氨酸,甘氨酸,精氨酸,乙酸钠,硫酸亚锰,氯化钙中选出可以提高植物乳杆菌冻干存活率的物质,其中脱脂乳粉,乳糖,海藻糖,蔗糖,甘油,侧金盏花醇可以有效的提高植物乳杆菌的冻干存活率;
步骤2:采用单因素试验,对脱脂乳粉,乳糖,海藻糖,蔗糖,甘油,侧金盏花醇浓度进行优化,选出最佳单因素比例,分别是脱脂乳粉12g/100g,乳糖9/100g,海藻糖6g/100g,蔗糖6g/100g,甘油3g/100g,侧金盏花醇3g/100g;
步骤3:采用析因试验进一步筛选最适保护剂,析因试验中保护剂的梯度设计如表1所示:
表1析因试验中保护剂的梯度设计
根据显著性分析,筛选出最好的保护剂为脱脂乳粉、乳糖和甘油;
步骤4:采用登高试验选出三种保护剂共同作用的最佳优化中心,登高试验保护剂的梯度设计如表2所示:
表2登高试验保护剂的梯度设计
脱脂乳粉g/100g 乳糖g/100g 甘油g/100g
1 9 7 2
2 10 8 2.5
3 11 9 3
4 12 10 3.5
5 13 11 4
采用上述表格的梯度设计,以菌种存活率为指标,得出最佳设计为3;
步骤5:以登高试验3的结果作为优化中心点,进行响应面试验,设计试验梯度为脱脂乳粉10g/100g,11g/100g,12g/100g;乳糖8g/100g,9g/100g,10g/100g;甘油2.5g/100g,3g/100g,3.5g/100g;以植物乳杆菌存活率为指标,得出最佳的冻干保护剂的优化比例为脱脂乳粉11.37g/100g,乳糖8.27g/100g,甘油3.06g/100g。
此种方法优化,其冻干存活率达到71.88%。比不使用冻干保护剂可以提高70.03%。
综上所述,在本实施例中,按照本实施例的植物乳杆菌复合冻干保护剂,本实施例提供的植物乳杆菌复合冻干保护剂,既可以优化配方,又可以发现保护剂彼此间作用关系,大幅度提高菌种冻干存活率。
以上所述,仅为本发明进一步的实施例,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明所公开的范围内,根据本发明的技术方案及其构思加以等同替换或改变,都属于本发明的保护范围。
