Description
技术领域
本发明涉及一种植物乳杆菌及其在制备保健食品、保健品和药品中的应用。
背景技术
当前肥胖的发生呈逐年上升趋势,世界卫生组织定义肥胖不是简单的体重过而是一种疾病。每年有超过260万超重或肥胖的病人遭受与肥胖相关的生理性疾病,如高血脂症,心血管疾病,糖尿病,骨质疏松等。随着社会的发展,生活水平的提高,人们的生活方式及膳食结构发生改变。高热量食物的摄入和运动量的减少,导致了肥胖发生率逐年上升。肥胖的发病机制尚不明确,肥胖的发生可能与遗传、内分泌失常、代谢异常及营养不平衡等因素相关。目前治疗肥胖的主要措施有调整饮食结构和类型、行为疗法;对于严重肥胖患者来说,还有服用减肥药物、肥胖外科手术等手段,但这些手段会降低病人的生活质量,例如长期出现腹泻,营养代谢紊乱等副作用。因此寻求安全、有效的预防肥胖发生的天然物质是研究的热点。
乳酸菌是可以产生乳酸的革兰氏阳性菌。酸奶,泡菜及人和动物的胃肠道、阴道中通常存在乳酸菌。由于其能促进肠道中有益菌的生长而被定义为有益菌。在乳酸菌中,乳杆菌具有很多生物学效应,它们可以干扰肠道菌群,非特异性激活人和动物宿主免疫系统,并且具有抗炎作用。乳酸菌可以通过一些机制来改善肥胖、炎症和相关的代谢并发症,包括黏附、定植在肠道表面,分泌抑菌物质,与致病菌形成竞争;上调黏附蛋白的表达,调节肠道菌群,与肠粘膜共同形成天然的保护屏障。
某些特定益生菌能有效地改善高脂饮食所引起的脂代谢紊乱、炎症、肠道微生态紊乱等现象,进而缓解肥胖的形成,将具有抑制脂肪沉积的益生菌开发为功能性制剂具有广阔的前景,值得深入研究。

2 实验方法
2.1 乳酸菌的分离纯化
将取回的泡菜水进行10倍梯度稀释,依次稀释至10-7。选择4个适宜稀释度(稀释度为10-4、10-5、10-6、10-7)分别取100μL涂布在MRS固体平板上,37℃培养48h后,选取形态各异的单菌落采用平板划线法分离菌株。重复上述步骤直至得到纯化菌株,通过革兰氏染色进行形态学观察。
2.2 PCR扩增16S rDNA序列
采用细菌基因组DNA提取试剂盒提取纯化菌株的DNA。采用25μL反应体系进行PCR扩增:模板DNA 1μL、上游引物(10μM)1μL、下游引物(10μM)1μL、2×Taq PCR MasterMix12.5μL,用无菌超纯水补足至25μL。PCR扩增条件:94℃预变性5min;94℃变性1.5min,55℃退火1min,72℃延伸1.5min,共30个循环;72℃末端延伸10min。最后委托华大基因科技有限公司对检测合格的PCR扩增产物进行双向测序,测序结果通过NCBI中的BLAST程序进行同源性比对分析。
2.3 API试剂盒鉴定
分离菌株在37℃培养18h,于3000r/min、15min的条件下离心收集菌体,用无菌生理盐水洗涤菌体后重悬为菌悬液。参考API试剂盒说明书进行操作。
3 结果与分析
3.1 分离菌株的菌落形态和细胞形态
菌株纯化后在MRS培养基中形成单菌落,菌落形态几乎一致,大多数呈圆形,白色,表面光滑湿润。革兰氏染色后在显微镜下观察到紫色细胞形态,判定为革兰氏阳性菌(G+)。菌株的菌落形态和革兰氏染色结果见图1。

注:“+”代表反应阳性;“-”代表反应阴性。
二、植物乳杆菌S58对小鼠肥胖的缓解作用
1 实验材料
实验菌株为植物乳杆菌S58(Lactobacillus plantarumS58),保藏编号为CCTCCNo:M2019595。
实验动物为8周龄雄性C57BL/6J小鼠,购自重庆恩斯维尔生物科技有限公司。饲养于室温25±2℃、相对湿度50±5%、12h光照/12h黑暗的标准化实验室中,适应性喂养一周后开始实验。
2 实验方法
2.1 实验动物分组及处理
将小鼠随机分成正常组(NC)、模型组(HFD)、植物乳杆菌S58(HFD+LP.S58)三组,每组10只。实验周期12周,NC组摄入基础饲料,HFD组和HFD+LP.S58组摄入高脂饲料,各组动物均自由饮水。NC组与HFD组每天灌胃10ml/kg·BW生理盐水,HFD+LP.S58每天灌胃1010CFU/kg·BW植物乳杆菌S58菌液。实验期间每7天称量一次体重,调整灌胃量。12周末,收集各组小鼠粪便,所有小鼠禁食不禁水18h,摘眼球取血,于4℃、3000r/min离心10min收集血清,-80℃保存备用;取血后脱颈椎处死,解剖取出肝组织、结肠组织、附睾脂肪组织,迅速称量肝组织、附睾脂肪组织重量;剪取适量大小肝组织、附睾脂肪组织,立即放入10%福尔马林溶液中固定48h;然后将所有组织置于液氮中冷冻,最终放入-80℃保存。
2.2 组织切片观察
固定好的组织经脱水、透明、浸蜡、包埋、切片后进行HE染色,最后在光学显微镜下观察组织形态变化。
2.4 血清指标的测定
按照试剂盒说明书对小鼠血清中TC、TG、LDL-C、HDL-C、AST、ALT、AKP、ADP、LEP、GLP-1、PYY、LPS、IL-6、IL-1β、TNF-α、IFN-γ含量进行测定。

表2 实验中用到的引物序列
3 实验结果与分析
3.1 植物乳杆菌S58对肥胖小鼠体重的影响
造模过程中体重变化直观的反映了小鼠肥胖状况,高脂膳食小鼠体重每周平稳增长如图3(a)所示。12周末HFD组小鼠体重高于NC组体重20%,提示肥胖模型造模成功。HFD+LP.S58组小鼠体重增长得到很好的抑制。
12周末体重增加量更直观地显示了各组小鼠体重的变化,如图3(b)。高脂膳食造模后,HFD组(10.82±2.19g)体重增量比NC组(4.13±1.16)增加了61.85%。LP.S58干预治疗后,HFD+LP.S58(7.15±1.23)组体重增量比HFD组(10.82±2.19g)下降了33.92%。
3.2 植物乳杆菌S58对肥胖小鼠肝指数、脾指数、附睾脂肪指数的影响
脏器指数可以反应动物的生理状态。长期的高脂膳食会导致机体出现应激反应,肝脏脂质堆积导致导致肝肿大。另外,还会使脾脏胸腺等免疫器官发生变化。如图4(a)、4(b)所示,与HFD组(5.27±0.23)相比,HFD+LP.S58组(4.07±0.25)的肝指数下降了22.96%,而脾指数HFD+LP.S58组(0.29±0.07)则比HFD组(0.84±0.13)下降了65.48%。
衡量动物肥胖程度,不能单单依靠于体重的变化,还要依据于其体内脂肪的含量。附睾脂肪指数是小鼠附睾脂肪重量与体重的比值,更直观的反应了动物的脂肪积累程度。长期高脂膳食诱导小鼠形成肥胖,会使小鼠脂肪重量增加。如图4(c)所示,HFD组(4.80±1.38)附睾脂肪指数显著高于NC组(2.36±0.57),而经过LP.S58干预后,HFD+LP.S58组(2.81±0.97)附睾脂肪指数则比HFD组低41.46%。
3.3 植物乳杆菌S58对肥胖小鼠脂肪组织形态的影响
脂肪组织脂肪泡直径的大小能直观的反应小鼠的肥胖程度,由图5可知,HFD相较于NC组来说,脂肪泡直径增大,而HFD+LP.S58组相比于HFD组来说则减小。
3.4 植物乳杆菌S58对肥胖小鼠肝脏组织形态的影响
研究发现肥胖和脂肪肝的发生密切关联,肥胖机体常常会引起肝功能损伤。在正常肝组织内,肝细胞脂质的合成与排泄是保持动态平衡的,一般没有脂质堆积,不会有脂滴形成,然而当脂质在胞浆内,就会形成大小不等的脂滴,破坏肝细胞正常结构,影响肝脏功能。如图6所示,NC组小鼠肝细胞无脂肪变性等异常改变,肝组织结构清晰、完整,肝小叶结构正常,细胞界限清楚,细胞核位于中央。而HFD组肝组织小泡性脂肪变性,肝组织的脂肪含量增多,有大量脂肪空泡,细胞内容物流出,细胞肿胀,细胞壁完整性破坏。经过植物乳杆菌S58干预后,肝组织脂肪变性程度较HFD组显著减轻,肝细胞脂肪空泡更小更少,形态与NC组相似。
3.5 植物乳杆菌S58对肥胖小鼠血清TC、TG、LDL-C、HDL-C的影响
当机体长期摄入高脂膳食,机体脂肪分解会加速,抑制脂质合成,产生过多的脂肪酸,使血清甘油三酯(TG)、总胆固醇(TC)水平增加。同时机体肥胖时,肝脏脂肪酶加速清除HDL-C(高密度脂蛋白胆固醇),使HDL-C含量降低,LDL-C(低密度脂蛋白胆固醇)含量升高。如图7所示,小鼠饲喂高脂膳食后血清TC、TG、LDL-C均显著升高,HDL-C显著降低,LP.S58能显著降低血清中TC、TG、LDL-C含量,显著升高HDL-C水平。
3.6 植物乳杆菌S58对肥胖小鼠血清ALT、AST、AKP的影响
肝脏是人体最大的解毒器官和脂代谢中心,谷丙转氨酶(ALT)、谷草转氨酶(AST)和碱性磷酸酶(AKP)是肝脏功能诊断的重要指标,能够反映肝脏异常的程度。ALT和AST主要分布于肝细胞中,肝细胞坏死时ALT与AST便会释放于血液循环中,使血清酶上升,其上升的水平和肝组织异常的程度呈正相关。由图8可知,NC组中ALT、AST、AKP含量最低,而HFD组中ALT、AST、AKP含量最高,LP.S58作用后,ALT、AST、AKP含量相比于HFD组来说显著下降。
3.7 植物乳杆菌S58对肥胖小鼠血清LEP、ADP的影响
瘦素(LEP)是由白色脂肪组织分泌的蛋白质激素,其可以进入血液循环以调节饱腹感,能量消耗,炎症和免疫反应,研究已发现肥胖患者的血清LEP水平会增加,脂联素(ADP)是脂肪细胞分泌的一种内源性生物活性多肽或蛋白质,脂联素是一种胰岛素增敏激素,能改善小鼠的胰岛素抗性和动脉硬化症。如图9所示,与NC组相比,HFD组LEP含量显著上升,而ADP含量显著下降。而经过LP.S58干预后,LEP含量下降,ADP含量上升。
3.8 植物乳杆菌S58对肥胖小鼠血清GLP-1、PYY的影响
胰高血糖素样肽1(GLP-1)具有多种生物学效应,包括促进胰岛素分泌、控制食欲和抑制胃排空等作用;PYY与食物摄入、肠道蠕动和胰岛素分泌有关,作为一种肠道激素,PYY也有助于减轻肥胖。由图10可知,高脂膳食会使GLP-1、PYY含量显著下降,而补充益生菌后,GLP-1、PYY含量显著上升,且与NC组相当。
3.9 植物乳杆菌S58对肥胖小鼠血清LPS的影响
致病性肠道菌群刺激肠道上皮细胞的内毒素(LPS)产生和释放,同时,肠道菌群的紊乱造成了肠粘膜屏障受损,肠道通透性增加,从而使LPS轻松通过肠道粘膜层进入血液,随后LPS可以与细胞因子受体结合,从而引发促炎细胞因子的释放。通过消耗益生菌可以改变肠道菌群结构,从而改善肠屏障功能,减少肠上皮细胞分泌LPS,导致血液中促炎细胞因子的产生减少。如图11所示,NC组LPS含量最低,而HFD组LPS含量最高,益生菌能使LPS水平显著下降。
3.10 植物乳杆菌S58对肥胖小鼠血清IL-6、IL-1β、TNF-α、IFN-γ的影响
IL-6、IL-1β、TNF-α、IFN-γ是肥胖发生与发展中几种至关重要的促炎因子。IL-1β主要由单核巨噬细胞产生,可以引起肠道炎症和局部并发症。IL-6是一种由单核细胞、巨噬细胞、T细胞等多种细胞产生的多效性细胞因子,具有趋化白细胞,调节T细胞分化等多种功能。TNF-α可以通过NF-κB通路进一步激活其他促炎因子如IL-1β、IL-6等的表达,致使免疫应答紊乱。IFN-γ的主要生物学活性是免疫调节。由图12可知,相比较于NC组,HFD组IL-6、IL-1β、TNF-α、IFN-γ含量显著升高。LP.S58能减轻高脂膳食对小鼠造成的影响,使IL-6、IL-1β、TNF-α含量显著下降,但LP.S58对IFN-γ却无明显作用。
3.11 植物乳杆菌S58对肥胖小鼠肝组织中mRNA表达的影响
过氧化物媒体增殖物激活受体(PPAR)是调节目标基因表达的核内受体转录因子超家族成员,PPAR分为α,β,γ三种类型,其中PPAR-γ主要表达于脂肪组织中,与脂肪细胞的过度分化,脂肪细胞生成等分子机制相关,PPAR-γ不仅能调控脂代谢相关基因的表达,也是脂肪细胞基因表达和胰岛素细胞信号传导的主要调节者。C/EBP-α是脂肪细胞分化过程中起重要作用的转录因子,直接调节脂肪细胞分化。此外,C/EBP-α和PPAR-γ之间还具有协同作用,PPAR-γ的激活能引发C/EBP-α基因的表达,而C/EBP-α对PPAR-γ具有正反馈作用。SREBP-1c是脂质代谢相关蛋白的重要转录因子,包括脂肪酸合成酶(FAS)和硬脂酰辅酶A去饱和酶1(SCD1),另外,SREBP-1c还受PPAR-γ调控。CPT1是脂肪酸氧化过程中重要的一种限速酶,CPT1的水平变化与高脂血症疾病的发生有着密切的关系。LPL是一种蛋白水解酶,是脂代谢途径中的关键酶,其主要功能是催化血浆中的乳糜微粒和极低密度脂蛋白中TG分解为游离脂肪酸,并促进蛋白、磷脂和载脂蛋白的转运,从而促使HDL水平升高,因此,又称为TG水解酶。在肝组织中,HLS基因的高表达表明菌和糖可以减少脂肪酸摄入并且增强脂解作用,并因此缓解肥胖。
图13表示LP.S58对肝脏中PPAR-γ、C/EBP-α、SREBP-1c、FAS、SCD1、LPL、HLS、CPT1表达的影响,由图可知,与NC组相比,HFD组小鼠肝组织PPAR-γ、C/EBP-α、SREBP-1c、FAS、SCD1、LPL的表达量均显著增加,HLS、CPT1的表达显著降低,而LP.S58处理组则可以显著降低PPAR-γ、C/EBP-α、SREBP-1c、FAS、SCD1、LPL的表达,提高HLS的表达,且对CPT1的表达没有影响。
3.12 植物乳杆菌S58对肥胖小鼠结肠组织中mRNA表达的影响
肠道紧密连接蛋白主体是跨膜蛋白(claudin、occludin)和膜周蛋白(ZO)的复合体,其中ZO-1、Claudin和Occludin共同作用确保肠上皮紧密连接的功能正常。
图14示出了LP.S58对结肠中紧密连接蛋白ZO-1、Occludin、Claudin-5、Claudin-7表达的影响,由图可知,与NC组相比,HFD组中ZO-1、Occludin、Claudin-7的表达量均显著下降,经过LP.S58干预后,Occludin、Claudin-7的表达量有所上升,但ZO-1与HFD组相比没有显著变化;NC、HFD、HFD+LP.S58三组Claudin-5基因的表达量没有显著变化。
最后说明的是,以上实施例仅用以说明本发明的技术方案而非限制,尽管通过参照本发明的优选实施例已经对本发明进行了描述,但本领域的普通技术人员应当理解,可以在形式上和细节上对其作出各种各样的改变,而不偏离所附权利要求书所限定的本发明的精神和范围。
