Abstract
本发明公开了一株植物乳杆菌新菌株及其应用。所述的植物乳杆菌新菌株,命名为581,保藏于中国微生物菌种保藏管理委员会普通微生物保藏中心,其微生物保藏号是CGMCC No.13121,保藏日期为2016年10月18日。该菌株可适用于多种果蔬汁的发酵,提高果蔬汁中有机酸、游离氨基酸、维生素等有益物质含量,对部分果蔬汁的不愉悦风味也具有改善作用。同时该菌株具有良好的耐酸、耐胆盐特性,对小肠上皮细胞具有良好的黏附特性,可以顺利到达肠道、与肠道上皮细胞发生黏附。体内小鼠实验结果表明,该菌株具有肠道改善功能,对便秘模型小鼠具有良好的润肠通便功效。
Description
技术领域
本发明涉及生物技术领域,具体涉及一株植物乳杆菌新菌株,涉及该植物乳杆菌新菌株在改善肠道功能中的用途,以及该菌株为发酵剂在果蔬发酵中的应用,包括在饮料、保健食品开发中的应用。
背景技术
果蔬汁是时下年经人以及关注健康的中老年人热衷选择的一种饮品,因其具有丰富的营养、新鲜健康而备受青睐。采用益生菌生物发酵技术,对果蔬汁进行深加工,除了可以增加果蔬汁的风味或改善一些蔬菜汁的不良风味外,更可以提升果蔬汁的保健功能,提高果蔬制品的附加值。益生菌通过代谢果蔬汁中的碳水化合物、蛋白质等物质,产生有机酸、肽类、酶类等有益物质,同时,果蔬汁中本身含有的维生素、膳食纤维等营养物质仍然存在,结合益生菌株本身的功能特性,将为消费者提供更多的有益因素。
随着现代人饮食结构的变化、心理因素和社会因素的影响,便秘的发病率有逐渐增高的趋势。严重便秘可导致电解质和酸碱平衡紊乱,引起痔疮、下肢静脉曲张等疾病,影响人们生活。此外,由于肠道排便不畅导致的毒素或有害代谢物的积累与多种慢性疾病的发生发展息息相关。早在1908年,诺奖获得者梅切尼科夫就提出了慢性疾病肠源性假说,近年来的研究更证实了这一观点。益生菌在发挥其润肠通便等肠道调节功能时,具有安全、无副作用的明显优势。植物乳杆菌在肠道中通过代谢产生的乳酸等有机酸,能够维持肠道的生态平衡、抑制有害细菌的生长,并能促进肠道蠕动,增加粪便含水量,作用温和,对维持肠道正常的生理功能具有重要作用。
适用于果蔬汁发酵的益生菌株除需具备益生功能外,还需具备一定的发酵特性。果蔬汁相比常作为益生菌发酵基料的乳类制品,营养组成相对贫瘠或存在缺失。此外,一些果蔬汁或浓缩果蔬汁还存在pH环境偏低、渗透压环境偏高等特性,果蔬汁发酵专用菌株还需具备一定的耐酸、耐高糖或耐盐特性。
发明内容
本发明的目的在于提供一种可用于果蔬发酵的植物乳杆菌新菌株,且所述菌株具有改善肠道功能的益生作用,可以顺利到达肠道、与肠道上皮细胞发生黏附,并发挥润肠通便功能。
本发明的另一个目的在于提供上述植物乳杆新菌株在发酵果蔬汁,以及其他食品、饮料、保健食品、药品、饲料中的应用。
为了达到上述目的,本发明采用了以下技术手段:
本发明菌株分离自四川泡菜样品,经MRS接种培养、分离纯化后分离获得的一株乳酸菌株,经鉴定其属于植物乳杆菌(Lactobacillus plantarum),命名为581,分类命名为植物乳杆菌(Lactobacillus plantarum),保藏在中国微生物菌种保藏管理委员会普通微生物中心,其微生物保藏号是CGMCC No.13121,保藏日期为2016年10月18日。
该菌株的生物学性质如下:
(1)形态学特征:在MRS培养基上形成明显的圆形、乳白色菌落,边缘整齐,***,不透明,表面光滑湿润,直径在0.2-2mm之间。革兰氏染色典型阳性,显微镜观察下细胞形状为杆状,无鞭毛,不产芽孢,不运动。
