Description
技术领域
本发明涉及一株降低血浆氧化三甲胺和盲肠三甲胺水平的长双歧杆菌及其应用,属于微生物技术领域。
背景技术
心血管疾病是世界范围内致病率和致死率主要的原因,动脉粥样硬化(AS)是心血管的病理基础。动脉粥样硬化是一种慢性炎症性疾病,公认的AS的始动因素为动脉壁内皮损伤及脂质的沉积;危险因子为高血压,血脂升高,炎症,氧化高胆碱,肥胖,抽烟等。
肠道微生物基因组与人体基因组一起,通过与环境因素的相互作用,影响宿主的食物消化和新陈代谢、免疫反应和炎症、神经活动等多种重要的生理功能。肠道菌群及其代谢产物与宿主之间的相互作用,对于维持宿主的健康是必要的。肠道微生态的紊乱与许多疾病相关,包括糖尿病、肥胖症、炎性肠病、神经退行性疾病和肿瘤等。
有研究表明,肠道微生物主要通过细菌感染、调节胆固醇和脂质代谢、食物及微生物代谢产物三种途径对动脉粥样硬化产生影响。经膳食-肠道微生物-肝脏-氧化三甲胺(TMAO)途径产生的TMAO可以促进心血管疾病的发生发展。依赖微生物的三甲胺(TMA)/TMAO途径被证明与心血管疾病的发病机制相关,是心血管疾病的重要诊断和治疗靶点。益生菌作为膳食补充剂,已被消费者广泛接受。干预肠道菌群代谢,或许可以成为预防和治疗心血管疾病的方法之一。

实施例5:长双歧杆菌CCFM1218用于降低盲肠Ruminococcaceae UCG-009属的丰度
C57BL/6J小鼠分组、造模及处理方法同实施例2。
试验结束时,小鼠禁食禁水12h,腹腔注射10%的水合氯醛溶液麻醉后,取盲肠,按照粪便DNA试剂盒的方法提取盲肠DNA,利用二代测序仪对盲肠的V3-V4区进行16S rDNA菌群分析。
实验结果如图5所示。胆碱饲料组小鼠盲肠Ruminococcaceae UCG-009属的相对丰度显著高于对照饲料组,与胆碱组小鼠相比,灌胃长双歧杆菌CCFM1218显著降低盲肠Ruminococcaceae UCG-009属的相对丰度。
实施例6:比较不同长双歧杆菌对胆碱饲料喂养的小鼠的血浆TMAO的影响
小鼠造模及处理方法同实施例2,分别用16株不同株的长双歧杆菌灌胃胆碱饲料喂养的小鼠,检测血浆TMAO,如图6所示,只有CCFM1218具有显著的降低胆碱饲料喂养的小鼠血浆TMAO的能力,相比胆碱组下降了30.89%,其它长双歧杆菌均未显著降低胆碱饲料喂养的小鼠血浆的TMAO。
实施例7:利用本发明长双歧杆菌CCFM1218制造含该菌的发酵食品
选用新鲜蔬菜洗净后榨汁,接着进行高温瞬间灭菌,在温度140℃下高温热杀菌2秒后,立即降温至37℃,再接入本发明制备的长双歧杆菌CCFM1218菌剂发酵剂,使其浓度达到108CFU/mL以上,在温度4℃下冷藏保存,于是得到含有本发明长双歧杆菌CCFM1218活菌的果蔬饮料。
利用本发明的长双歧杆菌CCFM1218发酵生产制备其他发酵食品,所述发酵食品包括固态食品、液态食品、半固态食品。所述发酵食品包括乳制品、豆制品、果蔬制品,所述乳制品包括牛奶、酸奶油、干酪;所述果蔬制品包括黄瓜、胡萝卜、甜菜、芹菜、圆白菜制品。
虽然本发明已以较佳实施例公开如上,但其并非用以限定本发明,任何熟悉此技术的人,在不脱离本发明的精神和范围内,都可做各种的改动与修饰,因此本发明的保护范围应该以权利要求书所界定的为准。
