Description
技术领域
本发明涉及微生物技术领域,特别涉及一种缓解结肠炎的发酵乳杆菌XY18及其应用。
背景技术
结肠炎发病机理复杂,具体机制尚未研究清楚,但已有的研究表明结肠炎的发生可能与免疫异常、家族遗传、饮食习惯等因素有关。其中,炎症细胞因子平衡失调、氧化应激、肠道粘膜屏障功能受损都与结肠炎的发病机制密切相关。目前对于轻、中度结肠炎患者来说氨基水杨酸类药物——柳氮磺胺吡啶是治疗结肠炎的首选药物,但其治疗效果欠佳且易复发,还可能引起恶心、呕吐、头痛等不良反应,对患者的健康有一定的损害。因此,寻找和开发一种安全有效、毒副作用小的途径来实现对结肠炎的预防和缓解作用已成为一个热门研究内容。
益生菌是通过定殖在人体内,改变宿主某一部位菌群组成的一类对宿主有益的活性微生物。益生菌在人体中具有多种生理生化功能,如:调节宿主黏膜与系统免疫功能、调节肠道内菌群平衡、促进营养吸收、保持肠道健康等。乳杆菌属在发酵食品中均占有优势地位,也是应用最早、研究较多的益生菌菌属。使用益生菌预防或治疗结肠炎已成为一种重要的新途径,因此,筛选具有益生作用的乳酸菌,并对其功能、分子机制进行深入研究,进而将其用于生产,具有重要的科学意义及社会价值,还可以丰富我国具有自主知识产权的菌种库。

采自新疆新源县那拉提镇阿克吾孜尼草原的牧民家中的传统自然发酵酸奶,无菌勺子充分搅匀酸奶后,用无菌注射器吸取50mL到已灭菌的离心管中,装入低温食品采样箱内带回实验室冷冻保藏于-80℃的超低温冰箱中备用。
1.2乳酸菌的分离鉴定
分别取1mL酸奶样品,用无菌生理盐水进行10倍梯度稀释至10-6,然后取10-4、10-5、10-6 3个梯度的菌液100μL进行平板涂布,37℃培养24h~48h,观察并记录菌落形态。挑取平板上不同形态的菌落进行划线分离,经37℃培养48h后,再次挑取平板上不同形态的单菌落进行划线分离,如此重复多次,直至得到形态一致的纯的单菌落。
1.3乳酸菌的初步鉴定
挑取平板上的纯菌落接种于5mL MRS液体培养基中,37℃培养24h。取上述含菌培养基1mL于无菌离心管中,4000r/min离心10min后弃去上层培养基,菌体沉淀重悬于无菌生理盐水并进行革兰氏染色镜检。
在100倍油镜下,乳酸菌菌株细胞形态如图1所示,细胞形态为长杆,且不存在出芽生殖。
1.4乳酸菌的分子生物学鉴定
(1)提取DNA:将已纯的疑似目标菌株接种于MRS肉汤中,37℃培养18h~24h后,采用细菌基因组DNA提取试剂盒进行DNA提取。将提取完成的DNA做好编号,放于-20℃冰柜保藏备用。

1.5乳酸菌体外抗性检测
(1)耐受0.3%胆盐的能力:在MRS-THIO培养基(含0.2%巯基乙酸钠的MRS肉汤)中添加猪胆盐使其浓度为0.3%,121℃灭菌15min,将活化好的5mL菌种以2%(v/v)的接种量分别接入不含胆盐(0.0%)的MRS-THIO培养基和含0.3%胆盐的MRS-THIO培养基中,以空白培养基(未接菌的MRS-THIO培养基)为对照,37℃培养24h后,分别测定上述不同培养基的OD600值,按下式计算菌株对胆盐的耐受力:
经检测,发酵乳杆菌XY18在0.3%胆盐中生长效率为31.23%。
(2)人工胃液耐受性:
人工胃液的配制:人工胃液由0.2% NaCl和0.35%胃蛋白酶组成,按照对应的质量体积比分别称取试验所需NaCl和胃蛋白酶进行配制,用1mol/L的HCl将配制好的人工胃液pH调整为3.0,再用0.22μm的滤膜过滤除菌备用。

经检测,发酵乳杆菌XY18在pH=3.0的人工胃液中的存活率为94.55%。
实施例2发酵乳杆菌XY18的活化、发酵
2.1发酵乳杆菌XY18的活化
将发酵乳杆菌XY18以2%的接种量在MRS液体培养基中活化2次,37℃培养14h~18h,5000rpm离心5min,使用生理盐水洗涤两次后收集菌体,再次5000rpm离心5min,备用。
2.2发酵乳杆菌XY18的发酵
配置12%的脱脂乳于95℃灭菌5min,冷却至42℃后以5%接种量加入发酵乳杆菌XY18。混合后于42.0℃±1.0℃发酵12h。发酵后发酵乳杆菌XY18的菌体浓度为3.02×106CFU/g。
实施例3
50只雄性7周龄Balb/c小鼠饲养于温度为(25±2)℃,湿度为30%~40%,12h/12h的光/暗循环的环境中,自由摄入AIN-93G标准的饮食和纯净水。适应性喂养一周后将50只Balb/c小鼠随机分成组为五组:正常组、DSS(葡聚糖硫酸钠)组、柳氮磺胺吡啶组、纯奶组和LF-XY18(发酵乳杆菌XY18)组,每组10只小鼠。正常组外的其他组小鼠在第一周内饮用含2.5% DSS(w/v)的水溶液诱导结肠炎模型,随后自由饮用纯净水。整个实验周期中,柳氮磺胺吡啶组每日按浓度500mg/kg·bw进行灌胃;纯奶组和LF-XY18组每日按照45mL/kg·bw分别灌胃纯奶和发酵酸乳;正常组和DSS组按相同体积灌胃生理盐水。每日称取小鼠体重,每三天对疾病活动指数(DAI)进行测定。第21d小鼠禁食不禁水12h后腹腔注射1%水合氯醛0.02mL/g麻醉小鼠,采用眼眶取血,断颈处死。收集小鼠血液,于4000rpm冷冻离心10min取血清,保存于-80℃。同时,测量小鼠结肠长度并保存于-80℃,待后续指标测定。
3.1小鼠体重分析
小鼠的体重变化如图2所示。由图2可以明显的看出,在整个实验周期中,正常组小鼠的体重始终保持上升的状态;而除正常组外的小鼠均在第一周自由饮用2.5%的DSS水溶液后体重有明显的下降趋势,其中DSS组下降最为明显,纯奶组次之。一周后,小鼠体重开始恢复。LF-XY18发酵酸乳和柳氮磺胺吡啶都能缓解由DSS诱导结肠炎导致的小鼠体重下降,且LF-XY18发酵酸乳组的小鼠体重恢复趋势优于柳氮磺胺吡啶组小鼠。
3.2疾病活动指数(Disease activity index,DAI)测定
DAI指数按照表1和以下公式进行计算:
DAI=体重下降分值+粪便性状分值+便血分值
表1 DAI评分表
小鼠的DAI分值如图3所示。由图3可以看出,在第一周内,除正常组外的所有小鼠DAI值均显著上升,DSS组小鼠DAI指数上升最为明显,最高DAI值达到9.75±0.25分。一周后,所有小鼠DAI指数开始缓慢下降,LF-XY18组小鼠的DAI值下降速度最显著,且DAI最高值为7.00±0.23分,是除正常组外DAI分值最低的组别,显著优于柳氮磺胺吡啶组和纯奶组的DAI值。
结合3.1的体重分析表明,LF-XY18发酵酸乳可以明显缓解结肠炎小鼠的临床症状,使小鼠体重回升,减轻便血程度,且LF-XY18发酵酸乳效果优于柳氮磺胺吡啶效果次之,纯奶并无明显作用。
3.3小鼠结肠长度分析
小鼠结肠长度分析如图4,正常组小鼠的结肠平均长度为9.0cm±0.8cm,结肠长度最长,DSS组小鼠结肠平均长度最短,为6.6cm±0.6cm;LF-XY18组、柳氮磺胺吡啶组和纯奶组小鼠结肠长度分别为8.3cm±0.4cm,7.5cm±0.3cm,6.9cm±0.3cm。与DSS组相比,LF-XY18组小鼠的结肠长度增加了25.7%。
3.4小鼠结肠组织病理学切片检测
取小鼠结肠组织于多聚甲醛溶液中固定过夜,经过脱水、透明、浸泡、包埋、切片以及苏木精-伊红(H&E)染色后,于光学显微镜下观察结肠的组织形态。
从小鼠结肠组织的切片能发现(图5),正常组小鼠结肠组织上皮细胞完整,黏膜层连接紧密,未见明显的炎症细胞浸润,杯状细胞和隐窝结构清晰可见;而DSS组的结肠组织中有大量的炎性细胞浸润,肠壁黏膜层脱落,腺体排列紊乱,杯状细胞大量减少;与DSS组相比,柳氮磺胺吡啶组、LF-XY18组小鼠结肠黏膜损伤有所改善,杯状细胞数量有所恢复,但纯奶组小鼠结肠组织中仍可以观察到明显的炎性细胞浸润;除此之外,与DSS组相比,纯奶组结肠组织的恢复情况并不明显,肠壁黏膜层受损与炎性细胞浸润清晰可见。
3.5小鼠血清和结肠组织中细胞因子的测定
将收集的小鼠血清和结肠组织从-80℃冰箱取出,待解冻后,结肠于组织提取液中匀浆后,5000rpm离心15min获得上清液,将血清与结肠匀浆上清液按照Elisa试剂盒中的说明书进行实验,测定小鼠血清和结肠组织中IL-1β、IL-6、IL-10、IL-17、TNF-α和IFN-γ含量。
表3小鼠血清和结肠组织中细胞因子的测定结果
注:不同字母表示各组之间在P<0.05水平上具有显著差异,相同字母表示无显著差异,下同。
小鼠血清和结肠组织中细胞因子的测定结果如表3所示。由表3可以看出,正常组血清和结肠组织中促炎因子IL-1β、IL-6、IL-17、TNF-α和IFN-γ的含量最低,抑炎因子IL-10含量最高。与正常组相比,所有DSS诱导的小鼠血清和结肠组织中IL-1β、IL-6、IL-17、TNF-α和IFN-γ均显著升高,IL-10显著下降(p<0.05),其中DSS组促炎因子含量最高,抑炎因子含量最低。与DSS组相比,柳氮磺胺吡啶、LF-XY18发酵酸乳均显著降低小鼠血清和结肠组织中的促炎因子的含量(p<0.05),而纯奶组促炎因子含量与DSS组并无明显差异。不仅如此,灌胃柳氮磺胺吡啶、LF-XY18发酵酸乳可以显著增加小鼠血清中IL-10的含量(p<0.05),且LF-XY18发酵酸乳的炎症调节作用最显著。这表明LF-XY18发酵酸乳可以显著调节小鼠血清中炎症因子的水平,缓解结肠炎。
3.6小鼠血清和结肠组织中氧化酶活性的测定
取小鼠血清和结肠匀浆上清液按照生化试剂盒中的说明书进行实验,测定小鼠血清和结肠组织中SOD、GSH-Px和CAT的活性。
小鼠血清和结肠组织中氧化酶活性的测定结果如表4所示。如表4所示,DSS组小鼠血清中的SOD、GSH-Px、CAT活性最低,正常组则表现出相反趋势(p<0.05)。LF-XY18组和柳氮磺胺吡啶组小鼠血清和结肠组织中抗氧化酶的活性显著高于(p<0.05)DSS组,且LF-XY18组酶活性高于柳氮磺吡啶组。但纯奶组小鼠血清和结肠中抗氧化酶活性与DSS组无显著性差异。
SOD,CAT和GSH-Px是重要的抗氧化酶,可以平衡生物体内自由基的平衡。LF-XY18发酵酸乳显著增加了血清中CAT、SOD和GSH-PX的活性,表明LF-XY18发酵酸乳可以通过抑制氧化应激来缓解结肠炎,而纯奶并无明显作用。
表4小鼠血清和结肠组织中氧化酶活性的测定结果
3.7小鼠结肠组织中E-cad、Occludin、ZO-1、CLDN3水平的测定
将100mg结肠组织加入1.0mL的RNAzol中提取RNA。然后将RNA浓度调整为1μg/μL,反转录生成cDNA后,配制1μL cDNA、10μL SYBR Green PCR Master Mix、7μL无菌蒸馏水和上下游各1μL引物的混合溶液。在定量PCR仪中进行反应,反应条件为95℃、60s;95℃、15s,40循环;55℃、30s;72℃、35s;95℃、30s;55℃、35s。引物及内参(GAPDH)的序列如表2所示,并按2-ΔΔCt法对其相关基因进行分析。
表2引物序列表
小鼠结肠组织中E-cad、Occludin、ZO-1、CLDN3水平的测定结果如图6所示。从图6可知,与正常组相比,DSS组结肠组织中E-cad、Occludin、ZO-1、CLDN3的表达水平显著下降(p<0.05)。与DSS组相比,柳氮磺胺吡啶和LF-XY18发酵酸乳可以显著上调E-cad、Occludin、ZO-1、CLDN3(p<0.05)的表达水平,其中LF-XY18组相应基因的表达水平均略高于柳氮磺胺吡啶组。E-cad在维持上皮细胞形态稳定、调节细胞间黏附连接以及抑制细胞间离散等方面起着重要作用。Occludin又称封闭蛋白,分布于肠道、血管等组织的上皮细胞内。有研究表明,当肠道通透性增加,Occludin的表达水平就会降低。ZO-1为紧密连接支架蛋白,其结构两端分别可以与Occludin和Claudins相连,进而构成稳定的紧密连接结构。CLDN3是Claudins成员之一,也是跨膜蛋白的主要成员,负责调控紧密连接的通透性和维持细胞极性等作用。这表明LF-XY18发酵酸乳可以显著提高肠道紧密连接蛋白的表达,维护上皮结构的完整性,从而缓解结肠炎症状。
3.8LF-XY18发酵酸乳LC-MS成分分析
取100mg液氮研磨的组织样本,置于EP管中,加入500μL的80%甲醇水溶液。涡旋震荡,冰浴静置5min,12000rpm、4℃离心20min。取上清加质谱级纯水稀释至甲醇含量为53%,15000g、4℃离心20min,收集上清,进样LC-MS进行分析。
扫描范围选择m/z 100-1500;ESI源的设置如下:喷雾电压(Spray Voltage):3.5kV;鞘气流速(Sheath gas flow rate):35psi;辅助气流速(Aux Gas flow rate):10L/min;离子传输管温度(Capillary Temp):320℃;离子导入射频电平(S-lens RF level):60;辅助气加热器温度(Aux gas heater temp):350℃;极性(Polarity):positive,negative;MS/MS二级扫描为数据依赖性扫描(data-dependent scans)。
从LF-XY18发酵酸乳和纯奶LC-MS成分分析可以看出(图7),LF-XY18发酵酸乳和纯奶中总共检测出402种物质,其中有显著性差异的占160种(|log2FC|>0.01)。在具有显著性差异的160种物质中,显著上调的有96种,下调的有64种。上调最显著的化合物有3-吲哚乙酸(indole-3-lactic acid)和胞嘧啶(cytosine);主要下调的化合物有利血平(reserpine)、泰乐菌素3-醋酸酯(tylosin)和1-甲基鸟酐(1-methylguanosine)。160种差异代谢产物主要富集于ABC转运体、维生素消化和吸收、苯丙氨酸代谢、嘧啶代谢、癌症中的胆碱代谢、赖氨酸降解等KEGG通路上。
综上所述,发酵乳杆菌XY18可以调节炎症因子、改善氧化应激,保护肠粘膜屏障功能,通过发酵改变纯奶中的化学成分进一步缓解结肠炎。同时,LF-XY18发酵酸乳还能通过影响氨基酸和维生素的代谢,以及调控ABC转运蛋白来减缓DSS诱导导致的小鼠结肠炎。也就是说,LF-XY18发酵酸乳可以作为一个潜在的功能性食品或药品来缓解结肠炎,为解决当前药物治疗带来的不良反应提供新的思路。
